Choaky Berry

The Choaky Berry (Eugenia axillaris), also known as White Stopper, is a native evergreen shrub or small tree in the family Myrtaceae, occurring in coastal scrub, hammock forests, and pine rockland habitats of South Florida, the Caribbean islands, and parts of Central America. It belongs to the large genus Eugenia, which encompasses over 1,000 species of tropical and subtropical trees and shrubs — many producing edible fruits used locally as food. White Stopper typically reaches 3–10 metres in height, producing opposite, elliptic leaves with a leathery texture and small, white, four-petalled flowers with numerous stamens. The fruits are small, fleshy drupes that ripen from green through red to black-purple and are consumed by birds, which serve as the primary seed dispersers. The species is an important component of subtropical coastal and hammock ecosystems in Florida, providing food for frugivorous birds including warblers, thrushes, and vireos during migration. Its dense branching provides nesting cover for native songbirds. The IUCN classifies Eugenia axillaris as Least Concern. The name stopper traditionally refers to the genus's reported astringent properties — the juice of the fruit was used medicinally to treat diarrhoea. It is a valuable native plant for restoration and landscaping in South Florida gardens.
