Director, Florida Agricultural Experiment Station
Most landscapes are in large measure dependent on tree effects
for dimension, profile and perfection and trees may well be con-
sidered as an indispensable element in landscape composition.
Other plants, of course, are required for completeness but theirs
is the minor role. Without its complement of trees, it is seldom
that a scheme of planting, whether it be a street, roadside,
urban home or farmstead, has achieved its fullest objective.
Through the influence of trees, a residence, street, or other
site is set apart and given an individuality and, since trees are
in themselves the most permanent of plants, they impart to their
immediate surroundings a sense of permanence and stability.
Numerous and varied advantages are derived from ornamental
tree plantings but they are so obvious and so well known that
their further listing is needless. It is mainly a question of
variety and adaptability, for in Florida the number of available
varieties is so great that the choice is not a simple one. The
adaptability of a species for use in a specified location is of para-
mount importance and must be given consideration, for climate
and soils vary so that a tree wholly adapted to one location may
be entirely unsuited to another.
Tender varieties planted in an area subject to low tempera-
tures can but ultimately prove a disappointment as will many
species from colder regions when planted in the most tropical
sections. Soil type, and particularly soil moisture, also has an
important role, since many species naturally adapted to high,
dry lands do not find low, undrained soils conducive to sustained
vigor of growth. Neither can all varieties that in nature are
found on moist soils be expected to thrive in dry sandy locations,
even with regular fertilization and irrigation. However, as a
general rule, plants may be transplanted from moist to drier
locations with much better success than can dry-land plants be
moved to poorly drained areas. For seashore planting the num-
ber of adapted varieties is limited; few species can withstand
the combination of dune sands and exposure to salt spray.
The writer acknowledges his indebtedness to Drs. A. F. Camp and A. S.
Rhoads of the Experiment Station staff for several of the photographs;
to Mr. Erdman West, also of the Station staff, for aid in the identification
of many species; and to Mr. W. M. Buswell for the photographs in Figures
2, 32, 57, and 78, as well as for notes on many trees of the southern area.

Much will depend on the local situation where trees are wanted
as to which of the numerous species is best suited. The great
variation in mature size, habit of growth, and foliage and flower
characters make some especially well suited to street or roadside
planting, some to grouping, and others to specimen planting.
Thick foliaged, spreading types usually are preferred for shade
but because of the difficulty of growing lawn grasses and many
shrubs in densely shaded situations, there are conditions to which
those with more open tops may be better fitted. If planted about
a building, its size and style of architecture will have a bearing
on the kinds chosen. Palms seem to be ideally suited to Spanish
types but not so well to the English, while the reverse is true
with the oaks; tall-growing, narrow-headed trees may be used
to enhance the beauty and perspective of many types of larger
buildings but usually are not so appropriate to small, low cot-
tages or bungalows. There is a wide variety of suitable species
of trees available for most requirements. The range of both
native and exotic species includes palms, conifers, broadleaved
evergreens and deciduous sorts, with an extreme diversity in
size, shape and coloration of foliage, flowers and fruits.
It is difficult if not impossible to differentiate between orna-
mental trees and those of other classes or to choose any select
group and designate its members as ornamentals with the impli-
cation that those not chosen are without beauty or value for land-
scape planting. Differing as they do in size, shape, foliage and
flower, some may have a greater attraction or be better fitted
for specific locations, but there is no tree species that does not
have an individuality and some degree of beauty. Under some
classifications those that do not produce edible fruits or are of
little or no economic worth are termed ornamentals to the ex-
clusion of most fruit and many forest trees. Perhaps the bet-
ter use of the term ornamental would be the broader one that
would include any tree which, because of some character it may
possess, is desirable for inclusion in an ornamental planting.
Another source of some controversy is the indistinct and vaguely
defined dividing line between trees and shrubs, since many
small trees might well be called large shrubs and many large
shrubs appropriately termed small trees. In the list of trees
that follows are included those grown for ornamental effect
regardless of other uses or values. Plants attaining a height
of 12 to 15 feet or more and normally having a single stem are

Ornamental Trees

considered as trees, although in some instances the plant serves
both as a large shrub and a small tree.
The number of native tree species is exceptionally large but
the number of introduced ones quite probably is greater. Many
of the latter are so well adapted that they are now growing
wild in many places as escapes from cultivation. Trees from
all continents have found a congenial environment and there
are doubtless hundreds more of the world's tree species that
would thrive in some parts of Florida were they to be introduced.

SFlorida's varied landscapes owe much of their variety to the
widely divergent types of native trees. It would be anticipated
that with an elevation factor of but slightly over 300 feet, there
would be a monotonous similarity of tree growth throughout the
state. This condition, however, is far from true, as is evidenced
by the panoramic diversity offered by the hardwood hammocks,
open pine forests, cypress, titi and gum swamplands, palmetto-
dotted prairies, mangrove-, seagrape-, and palm-fringed keys
and seashores, oak-clad ridges, and stream banks lined with
numerous varieties of both hard- and soft-wood trees.
Among the native trees of Florida are some indigenous to the
New England, the Appalachian, and the South Atlantic and Gulf
Coastal Plains areas while others are found whose habitat in-
cludes the West Indian and Caribbean islands. Here the plant
life of the temperate zone merges with that of the tropics. Of
marine origin, Florida is both geologically and ecologically
young and of necessity had to draw the most of its plant life
from other regions. In northern Florida the trees are predom-
inantly those of the southern Appalachian region, while in the
southern peninsular portion, where congenial climatic condi-
tions prevail, they are identical or closely allied to those of the
neighboring Indian islands. Through the agencies of the sea
and southerly-coursing rivers, aided in part by birds and ani-
mals, Florida has drawn in past ages on a vast area for its now
native plant life. This situation, together with the probability
of the development of new species within the region, diversity
of soil types, obtaining climatic conditions, and slight difference
in elevation, has given to Florida a greater variety of native
tree species than any like-sized area of the North American
continent north of Mexico. About one-fourth of the species
native to the United States are found in Florida as indigenes.

Florida Cooperative Extension

Throughout the northern sections of the state trees of the
temperate zone are in greatest numbers, there being 50 or more
species in that area that are also native to the Northern and
Northeastern states and some 90 species that grow as natives
in other Southern states. Over half of the latter extend their
range well into the central parts of the state. Tropical trees
are in greatest abundance in favored locations of the extreme
There is appended a list of Florida's native trees, as well as
those from other regions growing as escapes from cultivation,
with notations as to those utilized for ornamental planting and
the general areas in which they grow.

Due to considerable variation in hardiness among tree species
as well as failure of some from colder regions to adapt them-
selves to warmer climates and because of differences in winter
temperature minimums between the northern and southern sec-
tions of Florida, comparatively few are wholly adapted to state-
wide planting. Differences in low temperature extremes within
the state are not great but within that range is a critical point
for many tropical plants that suffer more or less severe damage,
or death, when exposed for several hours to temperatures be-
low freezing. On the other hand, many trees of more temperate
climates apparently require a period of dormancy that is induced
by or coincident with low temperatures and short day length
and consequently do not find congenial environment in the warm
winters of the sub-tropics. Thus, in the choice of trees for a
given locality, climatic adaptability is of first importance.
Normal prevailing winter temperatures have brought about a
definition of regions within the state, designated as northern,
central and southern, to which certain plants are climatically
adapted. These areas are not separated by any distinct or regu-
lar lines of demarcation but have quite irregular boundaries
because of the influence on temperature exerted by elevation,
presence of large lakes, or proximity to the ocean and the Gulf
Stream. Any delineation of the areas according to a specified
temperature minimum would fluctuate from year to year with
seasonal variations so that their boundaries are necessarily
vague and broad rather than sharply defined. As the names
would indicate, the northern area includes generally that part
of the state lying north of a line through Marion County and

Ornamental Trees

subject to the heaviest frosts; the southern, that of the extreme
south having the warmest winter temperatures and extending
northward along the coasts approximately to Palm Beach and
Punta Gorda; and the central, that lying between the northern
and southern sections. In each area some parts have greater
protection on account of local factors and less hardy plants, not
adapted to the region as a whole, may be successfully grown.
The classification of the numerous species according to their
climatic restriction has not been wholly an arbitrary one but is
based on observation of trees growing in the different regions.
It is highly probable that with many, the range has been shown
to be too greatly restricted while with some, too broad a range
may have been indicated. This is due to the few trees of some
species planted, the limited number giving only a very general
idea of their climatic range.

Only vigorous, thrifty specimens, free of destructive parasites,
with attractive qualities unimpaired, can fulfill the exacting
requirements of those chosen for purposes of beautification. For
the most part their thrift can be insured by fertilization, regular
watering when rainfall is inadequate, correct and timely pruning,
and, if needed, control of insect pests and diseases. If a plant is
not worth some cultural attention it is not worth planting.
Because of their permanent character, trees are seldom re-
placed. Most of them, if at all adapted to the location, thrive
with little care; they require and receive less cultural attention,
as a group, than any other type of ornamental plant. In their
native habitat trees grow and thrive in spite of over-crowding,
extended droughts and other adverse conditions. Nevertheless,
the majority of them make a more vigorous growth and assume
a more natural symmetry if given adequate room for full de-
velopment and a regular supply of moisture and plant nutrient
materials. Tree growth is relatively slow and a long period of
time is required for mature development but by supplying the
needed cultural attentions their growth may be materially has-
Often the loss or slow establishment of a newly planted tree
is directly traceable to a lack of proper care in transplanting.
No particular skill or complex methods are required in the re-
moval of small trees from one location to another but too often

Florida Cooperative Extension

the operation is carried out in a manner better fitted to fence
posts than living plants. Since ornamental trees are seldom
planted in large numbers, the extra labor involved in careful
transplanting amounts to little. Adapted trees planted in large
holes with roots well spread and covered with fertile soil and
supplied with ample water rarely fail to grow satisfactorily
provided they are dug with a good root system which has not
been allowed to become dry in transit and the work is done in
a suitable season.
Nursery-grown trees, because their root systems are better
developed and more compact, are generally given preference over
those taken from the woods. In digging many of the wild plants,
it is impossible to secure other than a small proportion of the
root system which may result in a heavy percentage of loss in
transplanting or a slow start into thrifty growth. Since varia-
tion exists in leaf and other growth characters within the same
species of native trees, careful and intelligent selection and
propagation of only the most desirable types enhances the orna-
mental value of numerous species. Nurserymen handling this
type of material are the logical ones to make such selections and
by propagation of none other than the most desirable forms
they can add materially to the use and value of native plants
for ornamental planting.
Soil for filling in about the roots in planting may be enriched
by the incorporation of well-decayed leaf mold, manures or other
litter, and in addition to these, small quantities of muck on light
sands. Tarkage or steamed bone meal also may be added but
complete commercial fertilizers are seldom used until later.
Whether or not any such additions are made, all subsoils from
the holes should be discarded and only topsoil used in planting.
Trees are set at approximately the same depth as they stood
in the nursery row. The soil about the roots should be well
watered at time of planting. Thorough watering tends to com-
pact the soil and to bring the particles in close contact with the
root by elimination of air pockets. A basin-like depression left
about the tree is much better than a mound of soil, as the former
will collect rain or irrigation water while the latter will aid in
its run-off. A mulch of any coarse organic material helps to
conserve soil moisture and on decaying increases soil fertility.
Loss in transplanting many kinds of large trees may be re-
duced by covering the trunk and larger limbs at time of removal
with a 1- to 2-inch layer of sphagnum moss tied in place with

Ornamental Trees

suitable cord. The moss is kept damp for several weeks. Span-
ish moss may be substituted but it does not hold moisture so well
as the sphagnum.
Most deciduous trees are transplanted when bare of foliage
or during the cooler winter months. From early December
through February is generally the most satisfactory season
for transplanting, although some of the more tropical species
are moved at any season but preferably not during dry periods
unless irrigation is available. In summer, losses in small, newly-
set plants may be reduced by partial shading for a few weeks.
Conifers of all kinds, after they have attained some size, are
difficult to transplant with bare roots and are therefore dug and
transported with a ball of soil about their roots or are grown in
boxes or pots. Many broadleaved evergreens are handled in the
same manner, which makes possible their transplanting at nearly
any season and without severe pruning. In planting these "balled
and burlapped" plants it is not necessary to remove the burlap
holding the ball of soil; that part about the stem of the plant
is loosened and turned back so that all of the burlap is covered
with soil in filling the hole.
In many instances cultivated ornamental trees are under a
greater handicap in securing the required plant foods than are
trees growing in the forest. This is due in part to the close
proximity of pavements and to the common practice of remov-
ing from about the trees all fallen leaves or other litter which
would later have a fertilizing value. Scores of exotic as well as
many native trees are transplanted to situations very different
from their natural environments and often on much less fertile
soils. That they may make the wanted vigorous growth, it is
necessary to supply as far as possible those soil constituents
which may be lacking in the new environment.
Both bulky and concentrated forms of fertilizers are used to
advantage, particularly during the early life of the tree. Those
derived from organic sources are favored because of the longer
time required for all of their nitrogen to become available but
the ones made up of inorganic forms are by no means unsuited.
Complete fertilizers, derived from both organic and inorganic
materials, containing 3 to 5 percent nitrogen, 6 to 8 percent phos-
phoric acid, and 4 to 6 percent potash, are perhaps the most
widely used. The number of applications varies from 1 to 3
or more annually, the first being made in early spring and the
others at intervals until late fall. From 1 pound to as high as

Florida Cooperative Extension

50 pounds or more are applied per year, depending on the size
of the tree and the nature of the soil. As the tree increases in
size the area over which the fertilizer is distributed should in-
crease accordingly, the belt extending well beyond the spread
of the branches. Only with very young trees should fertilizers
be placed close to the trunk, since the bulk of the feeding roots
are not there but spread throughout the soil to distances usually
greater than the width of the top.
Trees growing on lawns may be heavily fertilized by making
holes with a crowbar or like tool at some distance from the
trunks and as far out as the spread of the branches. The holes
may be a foot or more in depth, about 2 inches in diameter, and
spaced 2 to 4 feet apart. They are filled with bone meal, tank-
age, dried blood or other not-too-concentrated fertilizer and
then closed with the heel or a small amount of soil. Manures
may be applied to large trees without injury to the grass by re-
moving sections of sod and taking out the soil underneath to a
depth of 10 to 12 inches; the hole is then filled with old stable
manure, firmly packed, and the sod replaced.

Some pruning, judicious in kind and amount, is required in
most trees that they may develop into the general shape wanted.
Nearly all species have a distinctive habit of growth and the
effort should be made to direct the growth to the end that a
natural symmetry will be effected and maintained. By pruning,
branching may in large measure be controlled as to height, the
symmetry of the head initiated, and crowding of main branches
as well as development of weak crotches eliminated. It is pos-
sible in many trees to change materially the growth habits by
severe and continued pruning which ordinarily is not practiced
unless for some unusual and specific reason. There is nothing
exceptionally difficult nor complicated in the pruning of young
trees and a limited amount of pruning will exert a strong in-
fluence on the trend of growth and ultimate shape.
The heavy cutting back common at time of transplanting
often results in the development of a bushy head that later
requires thinning to allow only a limited number of heavy main
branches to develop. Branches left should be fairly equally
distributed about the trunk and leave it at varying heights
rather than in whorls. However, when trees, as Terminalia

Ornamental Trees

catappa, have a distinctive natural tendency to whorl branching
no effort should be made to change it.
It may be necessary occasionally to remove 1 or more larger
branches from older trees. Such trees are more often "butch-
ered" than rationally pruned. If thinning of the head is required
the removal of branches should be so distributed that the shape-
liness of the tree is undisturbed and large limbs as well as smaller
branches are removed close to the trunk so that no protruding
stubs are left. Splitting, which often accompanies the removal
of large branches, may be avoided by first cutting the limb par-
tially through from the under side or, with very large ones,
making 2 separate cuts. In the latter instance the limb is first
cut off 2 to 4 feet from the trunk to remove most of the weight
and the final cut is then made close to the stem.
Protruding stubs often die back to the main trunk and serve
as a mode of entrance for decay organisms which may ultimately
weaken the tree or cause its premature destruction. All prun-
ing should be done with sharp tools so that as smooth a surface
as possible be left and the cut surface then covered with a pro-
tective wound dressing. Several kinds of wound dressings are
available and lead paint alone is quite satisfactory.
Time of pruning will vary with different species but, as a
general rule, the work should not be done when the trees are in
an active flush of growth. Deciduous trees may be pruned late
in their dormant season and evergreens at nearly any time ex-
cept when actively growing. Callous tissue develops slowly
on some dormant deciduous species and for that reason pruning
is deferred with them until just prior to their resumption of
active growth. Ornamental trees are not pruned as severely
as shrubs, so that ordinarily any pruning done will have little
effect on the blossoming of the so-called flowering sorts.

In the following list will be found a majority of those trees,
other than palms and most of those bearing edible fruit, planted
in Florida as ornamentals. A short description of most species
is given, with photographs of many, that will be of some aid
in identification and the choice of varieties suitable for different
parts of the state. Technical botanical descriptions are not
included as they are available from many sources. Owing to
the size of the area covered and the few trees of some species

Florida Cooperative Extension

planted, there is no doubt that many introduced species have
been unintentionally omitted.
Because of the multiplicity of common names and their vari-
able use, arrangement is alphabetical according to botanical
name. Throughout, for each, the genus and species is given

the scientific name. The common names are indexed.

Acacia auriculiformis A. Cunn. Leguminosae. Southern area.
Australia. This species, but recently introduced, shows promise
as an ornamental and windbreak tree in the southern areas. It
is of medium size, symmetrical and thick-foliaged, the leaves
(phyllodia) nearly falcate in shape, 3 to 6 inches long and 11/
to 2 inches broad. The branchlets have 2 or 3 acute or almost
winged angles. Its pods, 2 to 4 inches long, are usually curved
when mature. The tree apparently has few pests and has been
planted considerably in the southeastern area.
Acacia longifolia Willd. Sydney Golden Wattle. Southern and
Central area. Australia. An erect shrub that in some specimens
attains the size of a small tree. Its leaves (phyllodia) are ob-
long-lanceolate or linear and 5 or 6 inches in length. It is seem-
ingly well adapted to dry and exposed locations.
Acacia macrantha, a small tree from Mexico, is found occas-
ionally in the peninsular section. It is low and spreading with
very fine, bipinnate foliage of a somewhat bluish or steely color.
Acer rubrum L. Aceraceae. Red, Scarlet or Swamp Maple.
Southern, Central and Northern areas. Native. Found as a
native almost to the extreme southern parts of Florida, the red
maple is utilized to some extent for ornamental planting but
mainly in the more northern areas. It is not fast growing and
usually does not attain a large size. The tree is upright in
growth habit, forms a rather narrow head and will grow well
in partial shade. Its deciduous foliage is typically 3- or occa-
sionally 5-lobed and turns to bright scarlet and yellow in late fall.
Acer saccharinum L. Aceraceae. Silver or Soft Maple. North-
ern area. Native. The silver maple, found in the Apalachicola
valley, is a large deciduous tree with a heavy, branched head and

5-lobed leaves to 5 inches i
across that are pale green
above and silvery white be-
neath. In combination with
other trees, it is quite striking
when wind exposes the white
undersurface of the foliage.
The chief handicap to its use
in exposed locations is the
brittleness of the branches
which break easily in ordi-
nary windstorms.
Acer floridanum Chapm., Ia
the Florida or Southern sugar
maple, is found as a native in Fig. 3.-Baobab tree, Adanson
the richer soils of the central
and western parts of Florida. It is of decided ornamental worth
and is planted to some extent in the northern sections.
Adansonia digitata L. Bombacaceae. Baobab. Southern area.
Central Africa. Though grown but sparingly in Florida, the
baobab tree is of interest because of the immense diameter of
the trunk in old specimens. Some of the trees in their native
habitat a, said to be among
the oldest living plants and to Fig. 4.-Leaf and flower bud;

have attained a trunk dia-
meter of nearly 30 feet. The
digitately compound leaves
are usually with 5 leaflets, but
some have only 3. For a time
in late spring or early sum-
mer, the tree is without fo-
liage. The flowering season
is in mid-summer, the indi-
vidual blossoms pendant on
heavy peduncles, white, 5 to 6
inches across and lasting but
a very short time. The white
fruits have a hard shell and
contain a mealy or spongy,
acid pulp that is said to be
edible. (Figs. 3 and 4.)

Adenanthera pavonina L. Leguminosae. Red Sandalwood.
Bead Tree. Circassian Bean. Southern area. Africa and
Southern Asia. A moderate-sized, evergreen, quick-growing,
upright tree with small feathery, pinnate foliage. The pods
are 6 to 8 inches long, curling up as they mature and exposing
the hard, brilliant-red seeds which are sometimes used as beads.
The general shape is quite symmetrical and the tree is of de-
cided worth as an ornamental. Its flowers are yellowish in color
and borne in spike-like racemes but are not sufficiently striking
to place among the flowering trees. (Fig. 5.)
Agyneja impubes L. Euphorbiaceae. Southern, Central, and
Northern areas. China. This is a small, deciduous tree excep-
tionally upright in growth habit. It reaches a mature height of
some 25 feet and seems well adapted to sandy soils. Annual
branchlets are produced and may easily be mistaken for pinnate
leaves. The leaves and the very small flowers and fruits are
all borne on these deciduous branches. It is bare of foliage

from about mid-December until March but because of the au-
tumnal coloring of the leaves and its upright growth the tree
is well-fitted for many situations. (Fig. 6.)
Ailanthus glandulosus L. (A. altissima Sw.) Simaroubaceae.
Tree-of-Heaven. Northern
area. China. In adapted
situations this deciduous tree
is large, spreading and of
fairly rapid growth. It is
sparingly planted but in a
few instances is said to have
become naturalized. Its un-
evenly pinnate leaves are
very large, occasionally
nearly 2 feet in length, with
numerous oblong lanceolate
leaflets 4 to 5 inches long.
The leaflets have entire mar-
gins except for the base
which has 1 to 4 pairs of
coarse teeth that are glandu-
lar on the lower surface. The
odor of both the crushed
foliage and the male flowers
is objectionable to most per-
sons. The tree is planted to
some extent in cities of other
states because of its resist-
ance to smoke.

some areas it is becoming locally naturalized. Its chief use has
been as a dooryard shade tree but it probably has advantages
for windbreak use. In late spring, for a few weeks, the tree
assumes a dead appearance when defoliating. The leaves are

about 10 inches long, with 4 to 8 pinnae, each divided into 6 to
18 leaflets 1 to 11/2 inches long. The pods, quite conspicuous
when the foliage is shedding, are straw-colored, leathery, flat,
thin and shiny, 5 to 8 inches long. The greenish-yellow flowers,
borne in globular heads, are not so attractive as those of A.
Julibrissin. (Fig. 7.)

with more fern-like foliage, the leaves being longer and more
finely divided. They may also be distinguished by the small
gland at the base of the rachis in this species. The numerous
globular flower heads are pink with noticeably long stamens
and place the tree in the "flowering" class. In the northern
sections of the state the species is quite common, both as a
dooryard tree and in the wild. (Fig. 8.)

The species are hardy in approximately the order named,
fordi being the only one grown in the northern area. Montana
has reached a mature size in Alachua County but small plants
are injured by ordinary winter temperatures. Both fordi and
montana produce seeds that are a source of the widely used
tung oil or wood oil of the paint and varnish industries, the
former being grown in a commercial way in Florida.
All are of value as ornamental trees. They produce large

flowers in profusion and their foliage is large and abundant.
Other than moluccana, they are deciduous. Fordi's blossoms
usually precede the leaves in spring, while those of other species
appear later. Montana and moluccana often have 2 seasons of
blossoming in 1 year, the second occurring in late summer. Most
of the trees attain a height of about 30 feet and are spreading
in habit, with the exception of montana, which is more upright
in growth. On suitable soils, all are of rapid growth.

freely during winter and spring months. Of species in Florida,
the leaves are leathery, broad and 2-lobed. B. purpurea L. bears
reddish or purplish flowers 3 to 4 inches across; its variety alba
has white flowers. A variety termed Simpson's Pink is early
blooming, the flower pink and somewhat smaller than those of
other varieties. According to late classification it is possible
that many trees that are supposedly purpurea should be placed
under the species variegata. All are partially without foliage
during a part of the late winter. (Fig. 10.)
Bischofia javanica Blume. (B. trifoliata Hook.). Euphor-
biaceae. Southern and Central areas. Asia. A tall, fast-grow-
ing tree with quite distinctive, bronze-appearing foliage. The
leaves are alternate and trifoliate with variable crenate-serrate
leaflets 3 to 5 inches long. The flowers are small and inconspic-
uous; the fruits black and fleshy, about 1/4-inch in diameter.
Rarely seen in Florida but has made a vigorous growth on the
high lands of the central section.
Bixa Orellana L. Bixaceae. Anatto. Southern and Central
areas. Tropical America. A small tree, seldom reaching a
height of 25 feet, best known as the source of a dye, the anatto
of commerce. The large leaves are deciduous, broadly ovate
and long-petioled. Its rose-colored blossoms are borne in term-
inal panicles and are quite attractive. The fruits are globose
spiny capsules, bearing a resemblance to the chestnut bur, and
contain an orange-red pulp about the seeds. From this pulp
is obtained the yellow or orange dye extensively used in coloring
butter, cheese, soups, rice and other foods. In Florida the tree
is grown solely as an ornamental.
Bombax malabaricum DC. (B. Ceiba Burme). Bombacaceae.
Red Cotton-Tree. Southern area and warmer parts of Central
area. India. The red cotton-tree is a large, heavily buttressed
tree, often confused with Ceiba. The digitate leaves are 5- or
7-parted, usually 5, and the blossoms are red. For a short time
in late winter the tree is leafless and during this time it blooms.
Broussonetia papyrifera Vent. (Papyrius papyrifera (L)
Kuntze). Moraceae. Paper Mulberry. Central and Northern
areas. China. The paper mulberry, found growing as an escape
in the northern half of the state, is planted as a shade tree in
that area. The tree is deciduous, to about 40 feet in height, and
on well-grown specimens has a broad, round-headed crown. The
leaves are ovate, 3 to 8 inches long, coarsely toothed, often deeply
3- or 5-lobed, rough and dull-green on the upper surface. Its.

In China the bark is used for paper making but the tree is of
no economic importance in America.
Bucida buceras L. Combretaceae. Black Olive. Bucida.
Jucaro. Southern area. Native. Recently the black olive has
gained much favor because of its high degree of resistance to
wind damage and its potential value for street and windbreak
use. In nature it may have a single straight trunk or several
heavy stems and it reaches a mature height of about 40 feet.
Heavy and spreading branches form a broad head. The leathery
leaves, crowded at the ends of short branchlets, are variable in
shape and size, ranging from spatulate to obovate or oblong-
lanceolate and from 2 to 3 inches in length. Most of the branch-
lets terminate in a short spine. Neither flowers nor fruits are
of particular ornamental value.
Calodendrum capensis Thunb. Rutaceae. Cape Chestnut.
Southern area and warmer parts of Central area. Africa. A
large, evergreen tree, seemingly well adapted but rarely planted
in Florida. The ovate leaves are deep green, parallel-nerved, and
to 5 inches long. Its large lavender-colored flowers are borne
in profusion in large panicles in early spring.
Calophyllum inophyllum L. Clusiaceae. Alexandrian Lau-
rel. Southern area. Tropics.
Widely distributed through the Fig. 11.-Artabotrys uncinatus
tropics, this species is growing
as an exotic in Key West. Its
native habitat is near the coast
and it probably could be in-
cluded to advantage among the
few ornamental trees adapted
to such situations.
The tree is of medium size
with large, oval, shining and
leathery leaves, 3 to 4 inches
wide and about twice as long.
The leaf venation is character-
ized by numerous fine parallel
veins that are at right angles
to the heavy mid-rib. The new
growth of foliage is reddish in
color for a time like that of

the camphor and mango. The

Cassia spp. Leguminosae. Senna. Southern area and warmer
parts of Central area. Of the many species of Cassia, only a
limited few are grown in Florida, among them fistula, nodosa,
grandis, siamea and Beariana. All are small trees with pin-
nate leaves and are prized because of their flowers which are
so freely produced in large masses. Most are quite tropical in
requirement and should be planted only in protected locations.
C. fistula, the pudding pipe or golden shower, has large leaves
and in spring bears long, loose racemes of yellow flowers in
profusion. (Fig. 12.) The flowers of siamea are pale yellow
and in evidence most of the year.
C. nodosa, pink cassia, is also free-flowering, its blossoms
rose-scented, pink in color. The flowers of grandis are a paler
pink and those of Beariana an attractive yellow.
Castanospermum australe Cunn. Leguminosae. Moreton Bay
Chestnut. Southern area and warmer parts of Central area.
Australia. A tall, evergreen, glabrous tree with large pinnate
leaves and producing large yellow flowers in loose racemes. The
leaves are to 18 inches long with 11 to 15 broadly oblong thick

leaflets. Large pods, 7 or 8 inches long and 2 inches broad,
contain the large chestnut-like seeds which are said to be edible
if roasted. The flowering period is in spring and the size and
number of the blossoms places the tree among the truly "flow-
ering" sorts. (Fig. 13.)

utilized extensively for closely clipped hedges, for trimmed and
untrimmed specimens, for windbreaks, and for street and high-
way planting. They thrive on both acid and alkaline soils, mak-
ing a vigorous growth on dune sands, calcareous rocky soils,
the muck of the Everglades and the many other soil types of
the lower peninsula. One species in particular, equisetifolia,
withstands brackish soils and salt spray with no apparent
injury and is planted extensively on the seacoast. In many
places the tree is becoming naturalized through self-seeding
and is able to compete successfully with the native vegetation.
(Fig. 14.)

Fig. 14.-Seashore planting of Australian pine, Casuarina equisetifolia.
The hedge, formally pruned trees, and trees in the background all are of
this species.

There are numerous species but the ones most widely planted
in the state are equisetifolia, Cunninghamiana and lepidophloia,
with glauca, strict and others grown in lesser numbers. All
are tall trees and of exceptionally rapid growth. Cunningham-
iana is considered to be the most resistant to injury by low
The trees of this genus differ materially from others in that
they are leafless except for very minute scales at the nodes of
the branchlets. In appearance the trees resemble the pines to
some extent, the numerous wiry, pendulous branchlets commonly
being assumed to be needle-like leaves. The flowers are uni-

Ornamental Trees

sexual and the fruit is a cone containing numerous transparently
winged seeds. In different species the length and diameter of
the branchlets differ materially, as does the growth habit of
the trees. In equisetifolia the branches are at nearly right
angles to the trunk for the most part and are not closely spaced
on the stem, which gives a quite open top in large specimens.
Lepidophloia has branches which are more upright and a much
thicker "foliage" which probably makes it more desirable for
many ornamental uses as well as windbreak purposes. This
latter species has not been known to seed in Florida and is
propagated by root suckers which sprout freely under the trees,
particularly on rocky soils.
Trees of the genus Casuarina, although non-leguminous, have
nodules on their roots in which fixation of atmospheric nitrogen
occurs. This is worth consideration in the choice of varieties
for economic plantings.
In some localized areas quite serious losses have been experi-
enced in Australian pine plantings due to a disease affecting
the roots. Dr. A. S. Rhoads has isolated the causal organism
of this disease, commonly termed mushroom root rot. A de-
scription of the disease with suggestions for control are con-
tained in Florida Station Bulletin 229, Diseases of Citrus in
Catalpa bignonioides Walt. Bignoniaceae. (C. Catalpa Karst.),
Catalpa. Indian Bean. Central and Northern areas. Native.
The catalpa is a round-headed, spreading tree that may attain a
height of 40 to 50 feet if given adequate room for development.
It is not considered as one of the most desirable ornamental
trees, being deciduous and, with many specimens, unsymmetrical.
The leaves are ovate, occasionally lobed, to 8 inches in length
and have an unpleasant odor. The flowers are white with 2
stripes of yellow within, and purplish-brown splotches in the
throat and on the lower lobes. They are borne in large, com-
pact panicles, the flowering season being in early summer.
Catesbaea spinosa L. Rubiaceae. Southern area. West Indies.
An evergreen, spiny, shrublike tree reaching a height of about
15 feet. The numerous wiry branchlets are armed with sharp
spines about an inch in length which slightly exceeds that of the
small-ovate leaves. It is a profuse bloomer, the creamy white
flowers, with slender funnel-shaped corollas several inches long,
being in evidence for several weeks during the late sum-
mer. The small, ovoid, yellowish fruits are produced in great

Ceiba pentandra Gaert. (Eriodendron anfractuosum DC.
C. Casearia Medic.). Bombacaceae. Kapok. Silk-Cotton Tree.
Southern and warmer parts of Central areas. Tropics. The
kapok, huge, massively buttressed and with its branches in
whorls extending horizontally at nearly right angles to the stem,
is one of the most distinctive trees growing in southern Florida.

Fig. 15.-Catesbaea spinosa.

In youth, the trunk is spiny. The deciduous leaves are digitately
compound, with 5-9 leaflets, usually 7, 4 to 6 inches long. Flow-
ering in summer, the great numbers of mallow-like, greenish-
white or pinkish blossoms are very attractive. Some 2 months
after flowering, the leathery, capsular, cucumber-shaped fruits
ripen, these containing about the seeds a silky, lustrous floss,

as a stuffing for cushions on ships
because of its buoyancy.
This species and Bombax, the
red-cotton tree, are sometimes
confused. The flowers of the lat-
ter are red or crimson, the leaves
with 5 or 7 leaflets, usually 5, and
the trunk and branches spiny.
sBoth are highly ornamental be-
cause of their unusual size and
appearance during the flowering
period. (Fig. 16.)

more under suitable soil con-
ditions. The leaves are small, 2 to 5 inches, ovate to oblong-
lanceolate, oblique at the base, thin, light green in color. The
fruits are small, sweet, globose drupes borne on rather long
pedicels. The tree is planted but sparingly as an ornamental

evergreen, leathery, pinnate leaves. Usually monoecious, it is
necessary that both pistillate and staminate flowering trees be
planted that fruit may be produced. (Fig. 18.)

A white flowered variety, alba, is also available.
Cercis chinensis Bunge, a Chinese species, has been introduced
and reported as making a satisfactory growth in the central
peninsular section.
Chilopsis linearis Don. Bignoniaceae. Desert Willow. North-
ern area. Southwestern United States. Although a native of
arid regions, the desert willow thrives in northern Florida and
is not uncommon as an ornamental plant in that area. The
plant is a small, shrubby, deciduous tree with willow-like foliage,
from which it derives its common name, and is valued for its
flowers and extended flowering season. Appearing first in
early summer, the trumpet-shaped flowers, which are white
to pale purple with yellow splotches in the throat, continue to
give a succession of bloom for several months.
Chionanthus virginica L. Oleaceae. Fringe tree. Old Man's

classed as a shrub, the fringe tree in Florida reaches a height
of 25 to 30 feet. It is not widely planted, perhaps because
of its slow growth and deciduous character. The greenish-

early spring at about the same time the leaves appear. The
oblate to oblong leaves are deep green, leathery, and from 4

areas. China and Japan. The camphor tree is common in the
northern parts of the state, where it seems best adapted, but is
by no means restricted to that area. On adapted soil types, it
is a large, spreading, round-headed tree, reaching a height of
50 feet or more. At best, however, it is slow-growing. Being
an evergreen, the foliage is attractive throughout the greater

part of the year except early spring. The flowers are incon-
spicuous; the fruits black, pea-sized drupes, produced in great
numbers and persistent for several weeks after coloring. The
tree may be adapted to parkway planting but pruning is re-
quired to overcome the low-branching growth habit.
This species is the natural source of camphor, which is dis-
tilled from the wood and leaves. The leaves when crushed
give off the distinct
camphor odor. The
discovery of a meth-
od for the manu-
facture of a syn-

this material has
reduced the demand
for the natural cam-

to ornamental planting but it might be used to advantage as
a windbreak tree. (Fig. 22.)

Colvillea racemosa Bojer. Leguminosae. Southern area and
warmer parts of Central area. Madagascar. A tree as yet
rare in Florida but promising to rival some of the better known
and best of the flowering species. Its leaves are quite large,
bi-pinnate and somewhat fern-like in appearance; there are
some 20 or more pairs of primary leaflets, each further divided
into as many as 28 pairs of secondary ones. The flowers are
borne in great numbers in long, loose racemes, the color bright
scarlet with showy yellow stamens. Those growers who have
flowering trees of the species are very enthusiastic over the
richness of the bloom and its value as a flowering tree. In
its native habitat, it attains a height of 50 feet.

geiger tree is small, slender-trunked, round-topped, with stout
branches and large, deep green leaves. Not widely planted
but of ornamental value for the large, orange colored flowers
borne in large clusters and in evidence most of the year. Sus-
ceptibility to cold restricts its use to the warmest areas.
(Fig. 25.)
Cornus florida L. Cornaceae. Flowering Dogwood. Central
and Northern areas. Native. Throughout the hammocks of the
northern sections, the flowering dogwood when in blossom in
early spring is a tree of rare beauty. The true flower is in itself
inconspicuous but is subtended by 4 involucral bracts or scales
that turn white and appear like petals to form a corolla-like cup
3 to 4 inches across. The tree is deciduous, rarely over 30 feet
high, usually much less, and its branches are more or less in
whorls and extend at right angles from the trunk. Small scar-
let fruits in tight clusters and the color change of the foliage
add to its ornamental value during the fall months. (Fig. 26.)
Couroupita guianensis Aubl. Lecythidaceae. Cannonball
Tree. Southern area. Guiana. This large, erect tree, rare
in Florida, is of interest because of its unusual flowers and
fruits as well as its close relationship with the tree producing
the Brazil-nut of commerce. The flowers are borne on heavy,
woody racemes several feet in length, attached to the trunk or
larger branches. They are large, of an unusual semi-folded

Crescentia Cujete L. Bignoniaceae. Calabash Tree. South-
ern area. Tropical America. The tree is small to medium-
sized with a low crown and wide-spreading horizontal to droop-
ing branches. The leaves are persistent, fascicled, oblanceolate
to spatulate, dark glossy green, 5 to 6 inches in length. Its
flowers develop from buds on the older wood of the trunk and
branches; they are usually solitary, pendulous, dark brownish
purple in color and from 2 to 3 inches in length. The heavy,
hard, indehiscent, gourd-like fruits are quite variable in size
and shape, ranging from ovoid to sub-globose and from 3 to
12 inches in diameter. The shell is smooth and thin but ex-
ceptionally hard and is filled with pulp containing the numerous
thin seeds. In areas where the tree is native, shells of the fruits
are utilized as cups or other vessels and for ornament, the
shell taking a high polish.

Dalbergia Sisso Roxbg. Leguminosae. Southern and Cen-
tral sections. India. This species is well adapted in Lake,
Pinellas and Lee counties; in the last named it has escaped
and is growing wild in a limited area. General appearance
of the tree and foliage is somewhat like the poplar, although
close inspection shows the leaves to be alternately pinnate with
4 or 5 obovate, abruptly acuminate leaflets. The flowers are
white, borne in cymes or panicles, but are too small to be of
much ornamental value. The tree is upright in growth habit
and is said to reach over 75 feet in maturity in its native
habitat and to withstand both severe droughts and flooding
for considerable periods without damage. (Fig. 31.)

Dillenia indica L. Dillenaceae. Southern area. Southeastern
Asia. Although of real value as an ornamental, this species
is seldom seen. The tree is symmetrical and of medium height
with shiny, oblong, serrate leaves 8 to 12 inches in length.
The flowers are pure white, 6 to 8 inches across, and the fruits
round and green, about 4 inches in diameter. The latter are
very juicy and considered edible although quite acid. Their
use is confined to the making of jellies and ades. (Fig. 32.)

blossoming. The flowers are pink, about 2 inches across and
freely borne in quite large, very compact, pendant umbels.
The leaves are usually 3-lobed, palmately nerved, cordate, 9
to 12 inches long and of about the same breadth, with a petiole
as long as the blade. Growth is very rapid.

E. indica Lam., of Asiatic origin, is adapted to the warmer
sections. It blooms in mid-winter, having the peculiar habit
of losing its foliage and shortly thereafter bursting into full
flower. Some of the trees are armed with sharp black prickles.

for avenue plantings as it has been difficult to get uniform
growth in many localities. Being gross feeders with wide-
spread root systems, the trees are seldom planted immediately
adjacent to citrus fruit groves or other fruit trees. However,
they are used in a limited way for windbreak purposes and
more generally as specimen shade trees. A large number of
species have been introduced but of these the following are

hundred species, is well represented among the ornamentals
of Florida. Two species, area and brevifolia, are native.
Nearly all are vigorous growers with handsome foliage. A
typical characteristic of most is the great number of aerial
roots hanging from the branches, many of which ultimately
reach the ground and thus form a tree with numerous trunks.

Florida Cooperative Extension

Among the many species there is a wide variation in size, shape
and texture of the leaves. The fruits, too, vary widely; they
are typical figs ranging in size from that of a pea to that of
the cultivated fig and in color from yellow and purplish to a
bright red, and of most species are inedible.

Fig. 34.-Hinau tree, Elaeocarpus dentata.

Most of the species are tropical or sub-tropical in climatic
requirement and cannot be grown in the cooler portions of the
state, some of the vines and the cultivated fig excepted. Good
soils do not seem essential to a thrifty growth although, with
many, well-drained locations appear better suited.
No attempt is being made to list all of the species in Florida,
since many are present in only small numbers. However, for
those who are interested in the genus, there is a wide field for
trial as the greater majority of the world's species have yet to
be introduced. F. altissima Blume, the lofty fig, is a native of
India and one of the taller growing species. It has thick, shin-
ing, large leathery leaves and comparatively few aerial roots.

Ornamental Trees

The main trunk is quite heavy and the tree is well suited to
street or parkway planting. (Figs. 37 and 43.) F. area
Nutt., the native Florida strangler fig, is a rapid-growing tree
of the hammocks in southern areas. Seeds dropped by birds
in crotches or crevices of other trees sprout there and the roots,
reaching the ground, are entwined about the trunk of the tree
on which they grow. These roots, as well as the tree top, grad-
ually increase in size with the result that the supporting tree is
finally killed. When planted in the open, the tree has numerous
trunks like the banyan and covers a large area. The leaves are
3 to 4 inches long, leathery and dark green; the fruit small, ses-
sile and reddish purple. The tree is not well suited for orna-
mental planting unless ample room is available. (Fig. 38.)

F. benghalensis L., another Indian native, is the banyan
tree which is noted particularly for its size and numerous sec-
ondary trunks. The ovate leaves are to 8 inches long and the
small, crimson fruit are produced in great numbers.
F. benjamin L., commonly called the Java fig, weeping laurel
and Java willow, is a native of Malaya. It is a large spreading
tree with drooping branches and small, shining, ovate or oval
leaves. Well adapted to street or park planting. (Fig. 42.)
F. brevifolia Nutt. (F.

wild fig native to the
Keys and extreme south-

F. infectoria Roxbg., the Indian Dotted fig, is a fairly dense
growing tree, probably best suited for specimen planting. It
is deciduous, being without foliage for a short time. Leaves
are thin and small, seldom attaining a length of over 5 inches.

part of the tree. It is a handsome, medium to large tree with
quite distinct foliage. The long-petioled leaves are thin, light-
green and shining, somewhat heart-shaped, tapering to a long,
tail-like appendage. The trunk and branches are smooth and
quite free from the aerial roots so common to the genus. It is
very satisfactory for specimen or street planting. Probably
the world's oldest transplanted tree is 1 of this species grow-

green above and rusty beneath. An abundance of aerial roots
is produced on the branches. (Fig. 42.)

is deciduous, the fan-shaped leaves, 2 to 31/2 inches across,
being in clusters of 3 to 5, on spurs and divided or incised at
the apex, turning yellow or golden in the late fall. The plants
are dioecious and because of the foul odor of the fruits, it is
best to plant only those bearing staminate flowers. (Fig. 44.)
Gleditsia delavayi Franchet. Leguminosae. Locust. Central

triacanthos) and water locust (G. aquatica), the former prob-
ably introduced and the latter native, the Chinese species dela-
vayi is adapted to the northern sections. The first 2 are little
grown as ornamentals and as the last has not long been intro-
duced it is rarely seen. It, however, is thriving in the north-
central section and where a tree of the type is desired is pos-
sibly the best suited. The tree is large, round-topped and
heavily foliaged. The leaves are deciduous and differ from
other species in the oblique leaflets of which the lower ones are
the smaller. Large strap-like pods, 12 to 20 inches long and
about 2 inches wide, are produced in great numbers. As an
ornamental the tree would be undesirable in many situations
because of the numerous long, branched, sharp spines on the
trunk and branches.
Gliiicidia sepium Steud. (G. maculata HBK.) Leguminosae.
Madre de Cacao. Southern area. Central America. Rarely
seen in Florida, this species is commonly planted in the tropics
as a shade for coffee and cacao. It is normally a small tree,
its leaves with 7 to 15 odd-pinnate leaflets, each with a blotch
of purple underneath. The flowers are pink, about % inch long,
and freely borne in large racemes in the spring when the tree
is partially or wholly without leaves. The fruit is a shiny, com-
pressed pod 4 to 6 inches long and about 1/. inch wide.
Gordonia lasianthus Ell. Theaceae. Loblolly Bay. Central

central Florida. The leaves are feathery in appearance, being
twice-pinnatified with 11 to 21 pinnae, the secondary lobes
usually about an inch long, entire or again lobed. The whole leaf
is 6 to 8 inches long and almost as broad; white silky on the
lower surface and deep green above. Large golden yellow or
orange colored trusses of flowers are borne in profusion for
several weeks, beginning usually in April. (Figs. 45 and 46.)

large, bi-pinnate foliage and ridged, flaky bark. The seeds,
once used as a coffee substitute, are borne in thick, fleshy, brown
pods that persist long after the foliage has shed. (Fig. 46.)
Hibiscus tiliaceus L. (Paritium tiliaceum Juss.) Malvaceae.

Ornamental Trees

Mahoe. Southern area. Old World Tropics. The mahoe grows
as a native or an escape on the Keys and in the extreme southern
peninsular portion of Florida. It thrives near the seacoast and
evidently has no aversion to brackish water. The tree attains
a height of about 30 feet and is striking because of its large
leaves and flowers. The leaves are rounded and leathery, 4 to
7 inches wide, and the hibiscus-like flowers -are pale yellow with
petals 2 to 21/2 inches long. Blooms in summer.
In some Pacific islands the inner bark is used for cordage,
mats and coarse cloth. The wood is durable and flexible.
H. elatus, Swtz. (Paritium elatum Don.), the mountain
mahoe, is a species with red flowers that appear in profusion
in winter, as well as sparingly in the summer. It is more erect
in growing habit than the above and is also found in the southern
area. (Fig. 46.)
Hicoria spp. Raf. Juglandaceae. Hickory. Southern, Cen-
tral and Northern areas. Native. Two hickories, alba, the
mocker-nut, and glabra, the pig-nut, are utilized extensively in
the northern sections as deciduous shade trees about houses,
outbuildings and barnyards, but it is seldom that they are
planted for such purpose, most having been left when the lands
were cleared of native timber. Both are large trees in maturity
and are well worth preserving in clearing for new building sites.
Hicoria pecan Brit. (Carya pecan Engl. and Graebn.), the
pecan, a native of the lower Mississippi valley, is widely planted
in the northern area as a shade tree and in some instances is
used for street planting. In the central and southern sections
an occasional specimen is seen but there the trees cannot be
depended upon for regular fruiting. The large trees are ideal
for summer shade and if of the right varieties, of which there
are many, they will furnish, in addition, the winter's supply
of nuts. There are situations where shade is wanted in sum-
mer but not during the winter months and for such places the
pecan, where soils are suitable, is ideally adapted. Full informa-
tion relative to pecan culture and varieties in Florida has been
made available in other publications.

are capsules divided into 12 to 15 sections, each containing a
single seed and exploding violently when mature. Prior to
the advent of ink blotters and when sand was used for drying
ink on paper, dried fruits of this tree are said to have been
used as sand containers, thus giving the tree its common name.
The tree is of value both as an ornamental shade tree and as
a novelty. Its reddish flowers are too small to place it in the
class of flowering trees. (Fig. 47.)

Ilex spp. Aquifoliaceae. Holly. Central and Northern areas.
Among Florida's 13 native Ilex species 6 attain sufficient size

the Chinese holly, cornuta, seem best adapted to the northern
sections although the dahoon and 1 other native, Krugiana, are
found in the extreme south. (Fig. 48.)
Holly has long had a significant part at the Anglo-Saxon
Christmas-tide and in America the use of the native American
holly, opaca, for decoration has threatened the destruction of
that species in some areas. So great is the demand that some

inches long, rectangular-oblong with 3 to 7 strong, sharp spines,
and very deep glossy green in color. The fruits are larger than
those of opaca but on specimens seen are not so freely borne.
Jacaranda acutifolia Humb. and Bonpl. (J. ovalifolia R. Br.
J. mimosaefolia D. Don.) Bignoniaceae. Jacaranda. Southern
and warmer parts of Central areas. South America. Because
of its profusion of bloom and delicate, fern-like foliage, the
Jacaranda is 1 of the favorite flowering trees of Florida. It
is a large, spreading tree, attaining a height of 40 to 50 feet.
The leaves are bi-pinnate, each having 16 or more pairs of
pinnae, each of which is again usually further divided into 16
or more pairs of leaflets. Long, loose panicles of large lavender-
blue flowers borne in profusion are in evidence from April
until June. For a short time prior to the blooming period the
tree is partially or wholly without foliage. The fruits are flat,
discoid pods about 11/2 inches in diameter; the seeds small
and broadly winged. (Fig. 48.)
Jatropha curcas L. Euphorbiaceae. Physic-Nut. Purging-Nut.
Southern and Central areas. Tropical America. The physic-
nut is a small tree much used in parts of the tropics as a live
fencing material about small areas. Large cuttings root rapidly
and livestock will not eat the foliage. Its large leaves are 3-
or 5-lobed and the greenish flowers are borne in cymes. Fruits
are olive-shaped, 1 to 11/ inches in length, and contain usually
2 oblong, black seeds each about 3-inch long. These seeds,
agreeable to the taste, are purgative in small amounts but poi-
sonous in large quantities. The kernels contain over 50 percent
oil which may be utilized in making soaps. The tree thrives
in the southern areas. (Fig. 48.)
Kigelia pinnata DC. (K. africana (Lam.) Benth.) Bignoni-
aceae. Sausage Tree. Fetish Tree. Southern area and warmer
parts of Central area. Tropical Africa. The sausage-tree is of
peculiar interest because of its status as a sacred tree in parts

of Africa and is planted as an ornamental novelty mainly for
its odd fruits which, in appearance, strongly resemble sausages
suspended by long cords. The tree is not large, rather unsym-
metrical in growth habit, and has large, odd-pinnate leaves, each

Formosa is yet quite rare in Florida but may be planted in the
cooler portions as a "flowering" tree. Its small yellow flowers
appear in early October in great terminal panicles and are
shortly followed by the bright red, bladder-like, papery cap-
sules containing the black, shot-like seeds. The capsules bear a
striking resemblance to the bracts of the Bougainvillea and
give the tree the appearance of producing a crown of red flow-
ers. The leaves are up to 18 inches long, bi-pinnate, with
numerous small, serrate leaflets. When given proper cultural
attention, the tree is
fast-growing. In its
native habitat it
reaches a height of
60 feet. (Fig. 50.)

and Northern areas. China. Through an error of some sort,
it seems that the 2 species lucidum and japonicum were confused
at some time in the past, and the correct names transposed;
each now being commonly known by the name of the other.
Japonicum is quite probably the 1 known as the wax privet
so widely planted as a large shrub.
The glossy privet is utilized as both a shrub and a small
tree, it attaining a height of about 25 feet. The leaves are
evergreen, ovate to ovate lanceolate, pointed and to 6 inches long.
Small, white flowers are produced in compact terminal panicles
in spring. Although grown occasionally in the central sections,
it seemingly is best adapted to the northern area. (Fig. 51.)

Liquidambar styraciflua L. Hamamelidaceae. Sweet Gum.
Southern, Central and Northern areas. Native. The native
sweet gum is found throughout nearly the whole of the state
except the extreme southern part. It is a vigorous grower,
pyramidal in general shape, very tall in maturity, and well
suited for avenue or shade where a deciduous subject is wanted.
The foliage is dense, the leaves are palmately 5-lobed and maple-
like in appearance, and turn to beautiful reds and yellows in
the late fall months. A winged, corky growth is conspicuous
on the branches. (Fig. 52.)

Liquidambar formosana Hance, a native of China, is a tall
species with 3-lobed, maple-like leaves that has shown adapt-
ability to northern parts of the state and would probably be
as well adapted as far south, at least, as the central area.
Liriodendron tulipifera L. Magnoliaceae. Tulip-tree. Yellow
Poplar. Central and Northern area. Native. This species is
among the largest of American trees and in maturity has a
broad spreading head with the straight trunk devoid of branches
to great heights. In youth the tree is pyramidal in shape. The
leaf blades are 4-lobed, 3 to 7 inches wide and about the same
length. The flowers are tulip-shaped with greenish-white petals,
nearly 2 inches in length and orange colored at the base. Occur-

Florida. The Southern mag-

Ornamental Trees

nolia, justly famous throughout the South, is a magnificent ever-
green tree of great size. It thrives under a wide range of soil
conditions and occurs naturally in nearly all parts of the state
except on poorly drained lands and in the extreme south. The
stiff, leathery leaves are oval-oblong, 5 to 8 inches long, deep
shining green above and rusty brown beneath. The new foliage
appears in early spring, coincidental with the shedding of the
old. In April, May, and into June there is a succession of the
large, creamy white, strongly scented flowers. The scarlet seeds
are borne in cone-like receptacles and mature in early fall. Al-
though slow growing, the tree is long-lived and once established
requires little or no cultural care. (Fig. 55.)
The sweet bay, also called swamp bay, grows in wet soils and
in transplanting its moisture requirements should be kept in
mind. It is a slender but tall growing tree with attractive
foliage and flowers. The leaves are bright green and lustrous
above but light gray beneath, which gives a silvery appearance
to the foliage when disturbed by
winds. There is a succession of Fig. 53.-The tulip tree, Liriodendrot

mainly planted for its fruit, the mango
tree has a distinct ornamental value. It
grows to a large size and if given room
for development usually has a spread of
top equalling or exceeding its height. It
is an evergreen with deep green, stiff,
lanceolate leaves that may reach a length
of a foot or more. In the new flushes of
growth, the foliage is wine-colored. There
are numerous varieties which give con-
siderable variation in general tree shape
as well as in foliage. In a limited way
the tree has been used for street planting.

in thin layers. The. flowers with protrud-
ing stamens that give the flower cluster
a bottle-brush shape, are white to yellow-
ish and favored by honey bees.
In a few areas the tree has spread
naturally from cultivation, this showing
conclusively its adaptability. It is little
injured by grass fires and in low areas
suffers little or none from poor drainage.

the citrus belt it is seldom tolerated as it is a favored host of
citrus whitefly. Attaining a height of 30 to 40 feet, with a
thick, spreading, round-topped head, the tree is attractive and
produces a dense shade. The variety umbraculifera Sargent,

small leaflets. The flowers, 1 to 11/2 inches wide, are yellowish-
white and sweet-scented, borne in panicles. The pendant, 3-
angled, 9-ribbed, slender pods, to 16 inches long, contain the
winged seeds which are the source of "ben oil" used for watch
lubrication. The fleshy roots have the flavor and odor of horse-
radish for which they have been substituted.

Olea europaea L. Oleaceae. Olive. Southern and Central
areas and warmer parts of northern area. Mediterranean
region. The cultivated olive makes satisfactory growth in most
well drained soils and is hardy throughout most of the state.
Trees of various ages are found here and there but it is a rare
exception that one produces any fruit whatever. Before the
trees attain much size, they are quite ornamental, the light
grayish foliage differing in appearance from that of most other
trees. A height of about 25 feet is the maximum reached and
by that time the trees have generally developed a somewhat
open head and unsymmetrical shape.
Pachira aquatica Aubl. Bombacaceae. Southern area. West
Indies. The few trees, presumably of this species, noted grow-
ing in southern Florida are more spreading than upright in
growth habit and are of peculiar ornamental value because of
their very showy flowers. The leaves resemble those of the
kapok tree-they are digitately compound, usually with 5 to 7
leaflets. Appearing in late winter or early spring, the very
large, tubular flowers with numerous scarlet stamens are very
unusual and attractive. The terminally borne flower buds, be-
fore opening, have the appearance of large, smooth acorns.'
Parkinsonia aculeata L. Leguminosae. Jerusalem Thorn.
Southern, Central and Northern areas. Tropical America. Of
drooping growth habit, the Parkinsonias with their thin, wiry,
pendulous foliage and green bark are quite unlike the usual tree
planted for ornament. They attain a maximum height of about
30 feet and are armed with short, sharp spines. Numerous
small bright yellow flowers, in loose racemes, appear in early
spring and are in evidence in lesser 'numbers for several months.
The leaves, pinnate with numerous very small leaflets, are us-
ually over a foot in length. Because of the nature of its foliage,
the tree has little value for shade but is valuable as an orna-
mental because of its free-flowering habit and unusual leafage.

Its white flowers are about 2 inches long and have a large
brown calyx. The smooth, fleshy, cylindrical fruits, which con-
stitute its chief attraction, hang from larger limbs and trunk
and resemble long yellow candles. They are about an inch in

having quite ornamental foliage and long panicles of violet flow-
ers that appear in spring before the leaves. It is said to be
growing as an escape in limited numbers in parts of the west-
ern section. The leaves are ovate, occasionally 3-lobed, from
5 to 7 inches long, darker green above, and with long petioles.
The tubular flowers are about 2 inches in length, pale violet
colored, with lower lobes marked by 2 yellow bands, fragrant,
and produced in terminal panicles to 10 inches in length. The
tree is rarely planted.

It is used extensively as a hedge plant, withstanding severe
clipping or shearing without injury, and is quite free of insects

tree at a distance appears somewhat like an orange tree. The
leaves are oblong-lanceolate, 2 to 4 inches long, usually with
entire margins but occasionally remotely serrate. Very small
white flowers in racemes 1 to 3 inches long appear in early
spring and are followed by the small oblong black fruits which
ripen in late fall. (Fig. 68.)

The native black cherry, thriving on sandy soils, is a fast-grow-
ing tree and is planted to some extent as an ornamental. It
attains a huge size under favorable conditions but as the wood
is brittle, it is severely broken up by storms. The foliage is a
shining green and, until the midsummer months, is quite at-
tractive. After that time, however, a disease causing leaf spot-
ting ordinarily occurs which imparts a more or less ragged
appearance until the time of leaf fall in late autumn. (Fig. 69.)

first 2 named are much longer-lived than the last and for this
reason are given preference. The first 3 are found in nearly
all areas other than the extreme south, so they may be properly
selected for planting anywhere except on the Keys. The largest
size, however, is attained by the trees in the northern areas.

banana, the traveler's tree, also sometimes called traveler's
"palm", attains a height of 30 feet and its appearance gives
the impression of a huge open fan. It derives its common name
from the storage of a watery fluid in the base of the leaf-stalks

the tree makes a thrifty growth but perhaps does not attain
the size as farther northward. In its native habitat the tree
reaches a height of 30 to 40 feet and has a short trunk, a
spreading head and long, pendulous branchlets. Leaves are
3 to 6 inches long, linear lanceolate, and taper to a narrow point.
Samanea Saman Merrill. (Pithecolobium Saman (Jacq.)
Benth.) Leguminosae. Rain Tree. Southern area. Central
America. The species much resembles the Pithecolobium that is
planted in the extreme south in both foliage and growth habit.
It attains an immense size in its native habitat and in many
tropical countries is used for roadside planting. The leaves are
numerously divided, usually bi-pinnate, with the leaflets 2- to
8-pinnate. Unlike the above Pithecolobium, its indehiscent seed
pods are seldom curved and the leaflets tend to fold together
in darkness or cloudy weather. The tree is yet rare.

growth habit is variable in different specimens, some being quite
upright and others spreading. Its foliage is dense, the pinnate
leaves attaining a maximum length of about 11 inches and with
7 to 13 leaflets that are 4 or 5 inches long. The fruits, ripening

in late fall, are produced in quantity, usually in clusters. They
are light yellow, about an inch in length, obovoid, are keeled
on the back, and have a thin layer of mucilaginous, almost trans-
parent flesh about the large black seed. The pulp of the fruit,
said to contain some 30 percent saponin, will form a lather in
water and has been used as a soap substitute. The seeds are
exceptionally hard
and have been uti-
lized as buttons and
beads. (Fig. 74.)

found growing as an escape. Its habit of growth is spreading;
the trunk usually unsymmetrical and divided into several large
branches. Thirty feet is about its maximum height. The
poplar-like leaves change in color in late autumn from a light,
shiny green to deep reds and yellows. Milk-white seed, 3 to the
capsule, are borne in profusion and adhere to the central column
of the capsule for weeks after opening. It is said that in China
the waxy coating of the seeds is used for candle and soap mak-
ing. Cultural requirements to insure thrifty growth are few,

Schinus terebinthefolius Radd. Anacardiaceae. Brazilian
Pepper Tree. Southern and Central areas and warmer parts
of Northern area. Brazil. A small, evergreen tree, often used
as a large shrub, that has very attractive foliage and for an
extended period in the winter months, numerous clusters of
small, bright red fruits. The leaves are 4 to 8 inches long, odd-
pinnate, with 5 to 9 leaflets. (Fig. 75.) Unlike the California
pepper tree, S. molle, it seems to be adapted to all but the
coldest areas and makes a very rapid growth.

Schotia latifolia Jacq. Leguminosae. Kaffir-Bean Tree. South-
ern area and warmer parts of Central area. South Africa. A
small tree, not over 30 feet, with pinnate foliage and bearing
much-branched clusters of rose-colored flowers in early spring.
The leaves are leathery, each with 4 to 8 ovate-oblong leaflets
1 to 21/2 inches long. (Fig. 75.)
S. brachypetala Sond., also from South Africa, is grown
sparingly in the same area as the above species. It is a small
tree with leaves having 8 to 10 leaflets and crimson flowers
borne in rather large panicles.
Sideroxylum foetidissimum Jacq. Sapotaceae. Mastic. Wild-
Olive. Southern area. Native. The native mastic is utilized to
a limited extent in the extreme south as a shade tree. It is very
large, having a heavy trunk and stout branches and reaching a
height of 60 or 70 feet. The leaves are bright green, lighter
beneath, thin but firm, oval to oblong, and 3 to 6 inches in
length. The fruit is olive-shaped, about an inch long, yellow
when ripe, and may be eaten.

Leaf of

Tropical Africa. This species is a tall, erect-growing evergreen
tree attaining a height of 60 to 70 feet. Its blossoms are among
the most showy of the flowering trees, they being large, scarlet,
and produced in immense numbers in short terminal racemes
which crown the tree with vivid color during the flowering
season. The large, odd-pinnate leaves are borne oppositely and
may attain a length of nearly 2 feet; the leaflets, variable in
number but usually about 15, are acuminate and to 4 or 5 inches
long. The broadly winged seeds are borne in long, flattened
capsules. Because of its rapid growth, adaptability and orna-
mental value of its flowers, the tree is gaining in popularity in
those areas not subjected to severe frosts. (Fig. 75.)
Stenolobium stans Seem. (Tecoma stains Juss.). Bignonia-
ceae. Yellow-Elder. Southern and Central areas. Native. Al-
though largely shrubby in growth, the yellow-elder attains in
some specimens a height of 20 or more feet and becomes more
of a tree. The foliage is odd-pinnate, the leaf length from 4 to

10 inches, with 7 to 13 lanceolate, acuminate, serrate leaflets
that are to 4 inches long. The flowers, appearing in late fall,
are funnelform, bright yellow, nearly 2 inches long, and borne
in profusion in large clusters. The plant is fast growing and
very desirable as a fall flowering specimen. (Fig. 76.)
Sterculia foetida L. Sterculiaceae. Southern area. Asia,
Africa. The general appearance of this tree is similar in many
respects to the kapok tree but it is not as large in maturity.
It is clean-limbed, with a smooth bark and branches somewhat
whorled. The deciduous leaves are digitately compound, each
with 5 to 9 oblong-lanceolate, acuminate leaflets that are 4 to
9 inches long. Appearing with the leaves, the flowers are a
purplish red and have a bad odor. The fruit, suspended singly
or in clusters on heavy stalks, is a large, smooth follicle, green
outside and bright red within, about 4 inches long, and con-
tains several large, hard, black seeds. The tree is yet quite
rare in the state but merits wider distribution. (Figs. 77
and 78.)
Swietenia mahagoni Jacq. Euphorbiaceae. Mahogany. Ma-
deira Redwood. Southern area. Native. The native mahogany
is gaining in favor as a shade and street tree in the warmest
sections. The Florida species ordinarily does not exceed a height

of 40 to 50 feet but with adequate room for development has a
well rounded top. It may be considered as an evergreen but
does lose its foliage in late spring and is partially bare of leaves
for a short time. The rather thick, pinnate leaves, with 3 or 4
pairs of ovate-lanceolate leaflets, are 4 to 6 inches long. The
tree does not make a dense shade.
Tabebuia pentaphylla (L.) Hemsl. Bignoniaceae. Southern
area. Central American Tropics. Although this species is said
to attain a height of some 60 feet in its native habitat, it is
doubtful that any in Florida have yet reached half that height.
The long-petioled leaves are digitately compound, with 3 or 5
leaflets which may be to 6 inches long. The pink flowers, 21/2
to 3 inches long, are borne in large terminal panicles in the
late winter or early spring months, a short time after the leaves
fall. The fruits are long, cylindrical pods containing numerous
winged seeds.
While young the trees (in many instances) seem unable to
maintain an upright position without support, although this
apparent weakness is overcome with age. The bark is light-
colored and irregularly furrowed. Tabebuia argentia, a native
of Paraguay, is a smaller tree with leaves having 5 to 7 leaflets,
silvery on both surfaces. Its flowers are yellow. (Fig. 79.)

area. Asia and Northern Africa. Grown mainly for its fruit
in Asia and Africa, the tamarind in Florida is not considered
in a commercial way and is planted only as an ornamental.
It is large, round-topped and spreading, usually low branching
and with a heavy trunk. The leaves are pinnate with numerous
leaflets and there is no season when the tree is entirely without
foliage. The fruits are pods with a hard, brittle shell that con-
tain a pulp about the seeds that is acid but of pleasing flavor.
Throughout the extreme south, the tamarind thrives in fertile
soils and is desirable where a large tree is wanted.
Terminalia Catappa L. Combretaceae. Tropical Almond.
Southern area. Southeastern Asia. Growing in a limited way
as an escape in the southern area, the tropical almond is adapted
to planting either inland or near the coast. It is grown on both
coasts-on the eastern as far north as Wabasso. The tree is
large and tall-growing with its whorled branches extending at
right angles from the trunk. The leathery leaves are obovate
in shape, some being nearly a foot in length. They are de-
ciduous, turning red before dropping, but the tree is seldom
entirely bare of foliage. Almond-like fruits about 2 inches long,
considered edible by some, are borne in quantity. (Fig. 1.)

Terminalia arjuna Bedd., a na-
tive of India, is a large tree with
much smaller leaves and fruits
than Catappa. Introduced and
planted by the Division of Foreign
Plant Introduction, U. S. Depart-
ment of Agriculture, at Miami, the
tree has shown not only its adapt-
ability to that area but also its
ability to withstand strong winds
with minimum damage. (Fig. 80.)
Other species have been intro-
duced and it is probable that some
of them will be as well adapted
as the 2 above.
Thespesia populnea (L.) Soland.
Seaside Mahoe. Southern area. Na-
tive. The seaside mahoe is a tree
of moderate size with spreading Fig. 82.-The Chinese elm, Ulmus pumila
branches, poplar-like foliage, and
showy yellow flowers that turn purplish with age. It occurs
naturally quite close to the coasts and is well suited for seaside
planting. The leaves are 21 to 412 inches long, prominently
veined, heart-shaped, acuminate, and long petioled. The large
bell-shaped flowers, 21/ to 3 inches across, are freely produced
in late spring or early summer. (Fig. 81.)
Thespesia grandiflora DC., of Porto Rico, is adapted to the
same area and uses as populnea, which it resembles, except for
larger leaves that attain a length of 7 to 8 inches, and large
flowers that are purplish red in color and 4 or 5 inches across.
Tilia floridana Sm. Tiliaceae. Linden. Basswood. North-
ern area. Native. The native linden is utilized as a deciduous
shade tree mainly in the northwestern section of the state.
Its foliage is typical ,of the group, the leaves broad-ovate and
coarsely serrate. The tree is upright with a fairly broad head
and fast growing. Neither the fruit nor the flowers have much
to recommend them from an ornamental viewpoint, although
honey produced from the flowers is said to be of exceptional

along stream banks, attaining a huge size. The growth is slow
but the tree is long-lived.
Ulmus pumila L. Ulmaceae. Dwarf Elm. Central and North-
ern areas. China. Another recent in-
troduction, this elm has proved to
be well adapted and exceptionally fast
growing. It attains a height of about
45 feet and has a spreading or round-
ed top at maturity. It does not give
a dense shade and holds its foliage
well into the winter. The thin leaves
are ovate to ovate-lanceolate, regu-
larly and simply toothed, and mostly
sharp pointed. (Figs. 82 and 83.)
Vitex Agnus-castus L. Verbena-
ceae. Chaste Tree. Hemp Tree. Cen-
tral and Northern areas. Southern
Europe. The chaste tree is common
in dooryards in the north-central and
northern sections as a shrub or small
tree. It attains a height of about 20
feet and is spreading in growth habit.
The digitate leaves have 5 to 7 lan-
ceolate leaflets, green on the upper
surface and grayish beneath, 3 to 4
inches in length. They have a strong
aromatic odor. The small fragrant
flowers, appearing in summer, are
lilac in color and produced in term-
