Bontia daphnoides was first discovered in Florida in the early 1990s (S. Zona 1998). Field studies are needed to determine whether flowers are pollinated by bees (as postulated by Zona), hummingbirds (R. J. Chinnock 2007), both, or neither. The fruits float and are adapted to dispersal by water. Bontia daphnoides has potential as an ornamental shrub, especially because it tolerates alkaline soil, salt, and drought. It is used medicinally throughout much of the Caribbean (E. S. Ayensu 1981b).
