Discussion
Species ca. 10 (1 in the flora).
Although it honors Plumier, the genus name has always been written as here treated.
Plumeria rubra Linnaeus, a native of Mexico and Central America, is often cultivated in frost-free regions of Arizona, California, Florida, and Texas and can be distinguished by its more open, corymbose inflorescence of pink, red, magenta, orange, or yellow (rarely white) flowers.
