Distribution

Old World in origin and is widely cultivated in the warmer parts of the world.

Note
|
Most of the Panamanian collections are from cultivated trees; Standley (1928) reports that it has also been found "wild." Ses- bania coccinea (L.) Pers., considered here synonymous with S. grandiflora, was proposed for trees with dark red flowers.
