---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Rosette-forming, colonial perennial of moist forests, cove forests, rock outcrops and well-drained bottomland forests. | Flowering stems unbranched, hairy. | Leaves basal, long-petiolate, broadly oval to nearly round, to 5 in. long, 3-7 lobed, palmately veined and sometimes mottled pale green or brown, toothed, hairy above; leaves evergreen in areas with mild winters. | Flowers in a crowded, glandular-hairy, terminal raceme that elongates and loosens with age, opening from bottom upward; white to pinkish-white (buds pink); about 1/3 in. wide; consisting of 5 spreading, pointed petals with basal claws, 10 long stamens and a conical ovary. | Fruit a conical capsule. | Spreads by runners to form small colonies. Native Americans once made a tea out of foamflower leaves to use as a diuretic and to treat sore eyes. | 10-12 in. | This perennial grows in rich wooded areas of the mountains and piedmont, spreading by runners to form small colonies. Its leaves are similar to those of the red maple and have hairs on the upper surface. Foamflower blooms April through June, producing a six-inch stalk topped by delicate white flowers. Because the stamens protrude beyond the petals, the flower resembles a crown or "little tiara", as the Greek word tiarella describes. | This perennial grows in rich wooded areas of the mountains and piedmont, spreading by runners to form small colonies.
