Heuchera richardsonii R. Br. Prairie alum-root
Prairie alum-root is a North American native. The genus, Heuchera,, pronounced HOY-ker-uh, honors German botanist Johann Heinrich von Heucher. The species, richardsonii, honors its discoverer, Sir John Richardson. "Alum-root" refers to the root's astringent properties—it contains compounds that can reduce the flow of blood from a cut. Identification: Plants take the form of a basal rosette—a set of leaves emerging from a central point near the ground. The leaves are slightly lobed into 7-9 palmate sections, with rough irregular edges, up to 3-5″ (7.6-12 cm) around. Each leaf is atop its own hairy stem. Leafless flower-bearing stems grow to a height of 2-4′ (60-121 cm). They are topped with inconspicuous green or greenish-white flowers, each about 1/8" long. Flowers appear from June to July.
