The Cahaba Lily grows only in running water on rocky shoals in the lower Piedmont. It is taller and more robust than its swamp cousin Hymenocallis caroliniana It will not survive on land nor in still water and is not known to grow in the Coastal Plain.

Cahaba Lily is also known as Shoals Spiderlily and I have seen it in growing in only one place outside its natural habitat and that was in a water fall rock garden. In comparison, H. caroliniana will grow in a variety of places as long as it is very wet.
