Gymnanthes lucida
Common Names Crabwood, Shiny Oysterwood, False Boxwood
Zones 10A–11
A subtle but ecologically important native of South Florida, the Caribbean, and Central America, Gymnanthes lucida is a small evergreen tree found in coastal hammocks, shell mounds, and limestone thickets. Its glossy leaves, inconspicuous flowers, and tolerance for salt wind and drought make it ideal for restoration and low-maintenance native landscapes. Though modest in appearance, it plays a vital role in stabilizing upland soils and supporting wildlife.
