Sapindus saponaria: Florida Soapberry

Edward F. Gilman and Dennis G. Watson


Introduction

Florida soapberry grows at a moderate rate to 30 to 40 feet tall. The pinnately compound, evergreen leaves are 12 inches long with each leaflet four inches long. 10-inch-long panicles of small, white flowers appear during fall, winter, and spring but these are fairly inconspicuous. The fleshy fruits which follow are less than an inch-long, shiny, and orange/brown. The seeds inside are poisonous, a fact which should be considered in the tree's placement in the landscape, especially if children will be present. The bark is rough and gray. The common name of Soapberry comes from to the soap-like material which is made from the berries in tropical countries.

Use and Management

Soapberry can be planted in low maintenance landscapes for the unusually prominent, orange-colored berries. They require little care other than some initial pruning to direct growth and to develop a strong branch structure. The bushy growth habit of this medium-sized tree combines nicely with shrubs and ground covers planted beneath and around the tree. Fruits attract the boxelder bug.

Florida Soapberry should be grown in full sun and will tolerate almost any soil. It is highly drought- and salt-tolerant.

Propagation is by seed.

Pests and Diseases

No pests or diseases of major concern.
