Discussion
Subspecies tuberosa is distributed mainly on the Atlantic Coastal Plain, but is occasionally found inland in river valleys east of the Mississippi River. The plants are especially common in eastern and central Tennessee. Sporadic occurrences further inland (for example, in Arkansas, Illinois) may represent introductions. Subspecies tuberosa is uncommon in Rhode Island (Kent County) and is considered to be of conservation concern there.
