It is a vigorous plant typically found growing wild in dry pastures, stony places and open wood. It grows well in average, medium, well-drained soil in full afternoon sun, although it tolerates light, sun-dappled shade. It prefers rich, constantly moist soils. It can be grown from seed or by division of the root stock, but division should be attempted only every 3 to 4 years. You should plant the tuberous roots 2 inches deep and 12 inches apart in the fall or early spring to flower in early summer. it is slow to get started but forms large clumps with time and may self-seed in the garden. The showy white trumpet-shaped flowers have yellow anthers and appear on 2-foot stems in clusters in spring to early summer. The foliage grows in clumps with grass-like leaves. Use in borders, rock gardens or along walkways and walls for edging. Diseases, Insect Pests, and Other Plant Problems: No significant problems.
