Simarouba glauca: Paradise-Tree1

Edward F. Gilman, Dennis G. Watson, Ryan W. Klein, Andrew K. Koeser, Deborah R. Hilbert, and Drew C. McLean 2


The pinnately compound, 16-inch leaves of paradise-tree have multiple, three-inch-long, shiny, leathery, oblong leaflets which are reddish when young. An upright tree when young, paradise-tree ultimately reaches 50 feet in height with a 30-foot spread and creates a dense, rounded crown at maturity. The tiny, inconspicuous, yellow to creamy white, springtime blooms on this frost-sensitive tree are followed by small clusters of dark purple, one-inch-long, edible fruits. Although paradise-tree produces desirable shade, the seeds and fruits are messy and will stain hard surfaces, and the shallow surface roots are troublesome to sidewalks and driveways and make it difficult to operate a lawn mower beneath the canopy.

Use and Management

The coarse leaf texture and light green, compound foliage allows this tree to "stand out" in a crowd. It could be used as a boulevard or median street tree. Plant them on 25- to 30-foot centers to form a solid canopy above.

Paradise-tree grows in full sun or partial shade on almost any well-drained soil. A native to south Florida, it will grow quickly on rich soils high in organic matter and should be protected from frost. Large trees are reportedly difficult to establish from containers, but there are no scientific studies supporting this notion.

Propagation is by seed, which germinate easily and rapidly. Young plants or seedlings are easily transplanted.

Pests and Diseases

No pests or diseases of major concern.
