Gardeners' Notes:

Positive NativePlantFan9 On Nov 21, 2004, NativePlantFan9 from Boca Raton, FL (Zone 10a) wrote:

Henry's Spider Lily is native and endemic to the wet fields and marshes and swamps on the Florida gulf coast in Gulf, Bay, and Walton counties in the northwestern Panhandle of Florida, from near St. Vincent Island up the coast to Walton County. It has white to near white(not greenish) flowers as the bloom color for the species here states. It is listed as endangered by the state of Florida; however, it is an excellent native plant for the Florida northwest Panhandle gulf coast (zones 8a and 8b) in native plant and average gardens!
