Coleus have been observed at this Station for use in a genetic study. It
has become apparent that more gardeners in the area could effectively use the plant
either as a summer bedding plant or a year-round potted specimen.

Historically the plant's tendency to attract mealy bugs and the discovery
of other plants with brighter coloration have relegated it to minor use. Malathion,
one of the most widely used home insecticides, now effectively controls the mealy
bug. New varieties of Coleus, with a wider range of coloration including bright
shades of red, purple, yellow, green and white permit the selection of almost any
combination of color. Although Coleus have been reported to be susceptible to
nematode injury, no difficulty has been experienced in the trials at this Station.

Coleus will grow either in open sunlight or fairly dense shade. Brighter
coloration and better growth have resulted when grown in 25 percent shade. Adequate
moisture and moderate amounts of fertilizer are essential to good growth. The
soil must be well drained or stem rotting may develop.

Coleus may be propagated by seeds or cuttings. The seeds germinate
readily but because of their small size many gardeners have little success.
Cuttings, either with one node or more may be taken at any time and are best taken
in the spring of the year for summer bedding plants. Rooting is equally satis-
factory in peat moss, sand or water. Soon after the roots appear the plants may be
placed in peat pots, flats, or pots with a soil mixture preferably including 1/3
to 1/2 volume of peat moss or compost. A sandy loam soil may be used with somewhat
less success. When the weather becomes warm the plants may be set in their desired

To develop a rounded bushy plant the terminals of the branches may be
'pinched' several times to cause additional branches to develop. For pot culture
some gardeners will prefer to prune off all side branches which will develop a tall
one-stem plant with especially large leaves.

Although grown primarily for the foliage, the Coleus plant wil form
attractive tall spikes of bluish flowers in the latter portion of t sate. er
and early fall. Drought conditions may induce early undesirable ow.rng. \

A number of seed companies and plant nurseries have t own s ns
varieties of Coleus. The pattern and coloration possibilities a ost li4 d.
In addition to many lots of seed grown at this Station, the follow ist t
introductions have been observed and are being maintained:
