Summary

In cultivation it tolerates sun to partial shade, preferring moist to well-drained soils with moderate summer watering and a dry summer dormancy; during dormancy keep cool and slightly moist; plant bulbs 4–6 inches deep and 4–12 inches apart in fall, and containers are possible; propagation from seed is possible but not easy, with most material grown from bulbs sold by specialty nurseries, and most plants take 3–5 years to flower; it is suitable for meadowscapes, rock gardens, woodland or oak forest understories, and coastal regions may receive full sun while inland sites prefer light shade; Sunset Zones 5–18.
