This southeastern species is restricted to seasonally wet, strongly acid soils, usually associated with Spagnum in sunny areas. In Ky. it occurs mostly on soils derived from the Corbin Sandstone of the southern Cumberland Plateau. An 1880s coll. attributed to WHIT (KY) is labelled just "Corbin" and could be from an adjacent county. However, this species was also discovered in WHIT during the 1990s.
