Evolvulus tenuis, a wide-ranging species native to Central and SoutlrAm ricawas-first
obtained from Andromeda Gardens in Barbados, W.I. by A.A. Will in 1982. This plant has
been under evaluation at the University of Florida's Fort Lauderdale Research and
Education Center since that time. It is being released in cooperation with Flamingo
Gardens, Fort Lauderdale, FL.

Evolvulus tenuis is a prostrate herbaceous perennial, but it can become woody with
age. It has small linear leaves .7 to 1" long which are light green in color and covered with

long white hairs. The plant is usually less than 6" tall, but can spread to a diameter of 2.5' or
more. Flowers are solitary, light blue in color, and borne along the stem in the leaf axils.
Flowering is year round if temperatures remain above 500 F.

Evolvulus tenuis is easily propagated by cuttings under intermittent mist. Typically, up
to 6 cuttings are stuck together to provide fuller plants. Rooting hormones are helpful, but

not necessary and cuttings are usually well rooted in about a month. Once rooted, they can
be transplanted into larger containers using a well-drained soil mix and moderate
fertilization rates.

Evolvulus tenuis makes beautiful hanging baskets and is excellent for use as a
groundcover in the landscape. Plants are best grown in light shade, but will tolerate full sun.
Since they are injured by temperatures below 500 F and are usually killed by frost, they are

) best treated as annuals in the landscape. They are not very salt- or drought tolerant.

Plants should be spaced about 15-18" apart in the landscape and will quickly form a

continuous mat of light green foliage and blue flowers. The plants do not root along the

stems in contact with the ground and so are easy to remove at the end of the season. Since

seed set has not been observed in Florida, there is little chance of this plant becoming a

There have been very few problems associated with this plant. No insect pests have

been observed on E. tenuis but it is susceptible to root rot diseases in overwatered

containers. It is not particularly susceptible to the blight that devastates E. glomeratus 'Blue

Daze', a related, but more erect and less free-flowering species.
