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.) |
Ipomoea macrorhiza has been confused with the Mexican and Central American I. jalapa (Linnaeus) Pursh; I. macrorhiza differs by having nocturnal, moth-pollinated flowers with white corollas versus matinal, bee-pollinated flowers with lavender corollas.
