Dwarf trillium, T. pussilum, comes in several varieties. It has a very interesting distribution, scattered across the south in very small and isolated colonies. Those populations differ enough that several varieties have been named. And renamed. And politely argued about in the literature. This one, grown in Edgewood Gardens, is likely var. georgianum. Some plants have little or no stem between the leaves and flowers. Because of that, this species is the only one that is at all intermediate between stemmed and sessile trilliums.
