There are three varieties of this species. The rarest, var. montana (Roan Mountain bluet) is a federally listed endangered species of the United States. It occurs only in the southern Appalachians along the border between Tennessee and North Carolina. It is named for Roan Mountain, one of a very few mountain peaks where it grows.[1][2]
