There are two subspecies of wild comfrey. The southern wild comfrey (C. virginianum var. virginianum) is rare in Connecticut, being listed by the state as a species of special concern. The northern subspecies (C. virginianum ssp. boreale) is even rarer; it is believed to have been eliminated from Connecticut. The photos below, which were taken in Michigan, show the northern wild comfrey.
