Phenology | Flowering and fruiting year-round. | Flowering and fruiting late spring–summer. |

Discussion | The geographical origin of Jatropha multifida cannot be determined with certainty; it is probably native to the West Indies. The species is widely cultivated throughout the tropics as an ornamental and has escaped and naturalized in many areas, including central and southern Florida.

In Arizona, Jatropha cuneata is found only in Pima County, primarily in Organ Pipe Cactus National Monument and Cabeza Prieta National Wildlife Refuge. Its stems have been used in basket making. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
