Heuchera parviflora Bartling var. parviflora. Common name: Cumberland Grotto Alumroot. Phenology: Jul-Sep. Habitat: Shaded cliff bases, usually under overhangs, on grotto floors, behind waterfalls where humidity is high but not in the spray zone, in rockhouses of the Cumberland Plateau, nearly always in deeply shaded situations where little or no direct sunlight falls. Distribution: An uncommon species throughout its range (s. OH, WV, w. VA south through e. KY to w. NC, nw. SC, n. GA [s. to Fulton Co.], and se. TN), H. parviflora is probably most common in the gorge and waterfall country of sw. NC and in the Cumberland Plateau of TN and KY.
Origin/Endemic status: Endemic
Other Comments: In deeply shaded sites, it is often the only vascular plant present.
