Heuchera parviflora Bartling — Cumberland Grotto Alumroot

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. An uncommon species throughout its range, H. parviflora is probably most common in the gorge and waterfall country of sw. NC and in the Cumberland Plateau of TN and KY. In deeply shaded sites, it is often the only vascular plant present.
