Ithuriel's Spear
Triteleia laxa
  
About Ithuriel's Spear (Triteleia laxa) 16 Nurseries Carry This Plant Ithuriel's Spear (Triteleia laxa) is a common native perennial herb in the Lily family that grows primarily in northern and central California. It tends to grow in openings in forest or woodland with sandy soil, at elevations from 0-4600 feet.

Grassy blade-like leaves emerge in late winter and begin to go dormant just before flowering. Loose purple, star-shaped flower clusters arise on foot-long stems in late spring to early summer. Numerous insects including bees and butterflies are attracted to the flowers, and some mammals will dig up and eat the corms.

Extremely easy to grow, Ithuriel's Spear prefers sandy soil but thrives even in clay soil and under native oaks. It can take full sun and will be healthier if allowed to dry out and go dormant in the summer but will survive regular irrigation. Plant the corms 4 inches deep and mass for best effect. It will naturalize over time among other plants or grasses.
