Summary
Ithuriel's spear is a cormous perennial native to western North America, including California and Oregon, with basal, grasslike leaves that wither during flowering and tall stems bearing umbels of six-petaled blue to blue-purple to white flowers; the plant grows about 0.3–0.6 m tall and is mildly fragrant.
It prefers full sun to partial shade on well-drained soils, is drought-tolerant once established, and requires regular moisture in spring but drying during summer dormancy; hardy to zones 6–10 and may overwinter in zone 5 with protection, and can be grown in containers; propagation occurs by seeds or division of corms, with seed taking 2–3 years to flower; it naturalizes readily and is suited for borders, rock gardens, native meadows, and wildlife gardens, attracting bees and butterflies and providing edible bulbs.
