Discussion | In the flora area, Ipomoea indica rarely produces seeds and rarely survives winters. It is probably native in southern Florida. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
In the southeastern United States, Ipomoea ×leucantha results from crosses between I. cordatotriloba and I. lacunosa that may be effected by honeybees (Apis mellifera); elsewhere, I. × leucantha is presumably introduced.
