Heuchera is a genus named for Johann Heinrich von Heucher (1677 - 1747, German Professor of Medicine). It comprises about 55 species of evergreen and semi-evergreen perennials from woodland and rocky sites in North America. Plants characteristically have tufts of long-stalked, rounded, cordate leaves originating from somewhat woody root stock, and slender, mainly leafless stems that bear narrow, loose to dense clusters of small, bell-shaped, 5-petalled flowers with saucer- to urn-shaped calyx tubes well above the leaves. Flowers are sometimes petalless and have conspicuous, colorful calyces. Leaves can be boldly veined, they are usually coarsely toothed or shallowly lobed into 5-7 sections. The fruits are capsules, 6-10 mm long, with tiny, dark brown, spiny seeds.
