Heuchera villosa Michaux. Common name: Crag-jangle, Rock Alumroot. Phenology: Late Jun-Oct. Habitat: In crevices of rock outcrops, or in thin soil over boulders, a characteristic component of the flora of high elevation cliffs and summits (to at least 1920 m), not particular about the rock type, occurring on a wide range of rock types in our area, including felsic gneisses and schists, mafic gneisses, granites, quartzites, and others, probably the most acidophilic of our taxa of Heuchera. Distribution: W. VA and s. WV south through w. NC and e. TN to nw. SC, n. GA, ne. AL (primarily a Southern Blue Ridge endemic).
Origin/Endemic status: Endemic
Taxonomy Comments: See H. macrorhiza for discussion of that taxon, not included in H. villosa in this treatment.

plant sale text: Beautiful green foliage gives this uncommon southeastern native perennial long-term appeal in the garden. The leaves and flowers of this species bear many fine hairs, hence its common name of Hairy Alumroot. Its dense rosettes of fresh green leaves require at least partial shade to look their best. Each plant grows into a handsome clump as it matures. Stalks of tiny white to pinkish-white bell-shaped flowers are borne on slender stems above the foliage in late summer. In the wild, Hairy Alumroot grows primarily in the mountains from Virginia and Tennessee south to Georgia.
