Tetrazygia bicolor Florida Tetazygia, West Indian Lilac

Edward F. Gilman


Tetrazygia is a marvelous large shrub or small tree that is native to south Florida (Fig. 1). The attractive, evergreen leaves of this 10- to 30-foot-tall plant are lanceolate in shape and have 3 conspicuous veins that run lengthwise. These leaves are dark green with silvery underside and attain a length of 3 to 6 inches. White or pinkish blooms with bright yellow stamens appear in the spring and summer. These showy flowers occur in terminal clusters that are 4 to 5 inches long. Purple or black berries ripen in the late summer and fall and are persistent on the plant. The fruits are edible, some say delicious, and the birds are very fond of them.

Use and Management

Tetrazygia can be used in the landscape as a specimen or tall hedge or screen. It is best to use a a hand pruner instead of a hedge pruner to clip the plant because leaves are large. Large leaves look best if they are not cut during the clipping process, and it is hard to avoid cutting leaves in half with a hedge pruner. Some consider this plant to be one of the best landscape plants for central and south Florida. Unfortunately, it is seldom grown or used. The foliage presents a beautiful, drooping display of coarse texture that will fit into any landscape site, provided there is ample room for its large size.

Tetrazygia bicolor will survive in full sun but prefers partial shade. It will tolerate drought and grows well on most well-drained soils.

Tetrazygia can be propagated from seed.
