Triteleia laxa (Ithuriels Spear)

Rewarding and easy care, Triteleia laxa (Ithuriel’s Spear) is a cormous perennial boasting loose umbels of up to 25 big, star-shaped, blue-mauve flowers in mid-spring to early summer.

Rewarding and easy care, Triteleia laxa (Ithuriel's Spear) is a cormous perennial boasting loose umbels of up to 25 big, star-shaped, blue-mauve flowers in mid-spring to early summer. The flowers are tubular, opening into a sharply six-pointed star. Rising on long, slender stalks, they open continuously for a month or more, extending the show for quite a while before the plant goes dormant in summer. The foliage of long, grasslike basal leaves emerges in late winter and dies back as the flowers appear. Easy to grow, undemanding, drought tolerant, beautiful and adaptable, Ithuriel's Spear is a charming addition to the landscape. Native from southern Oregon to southern California, it is often found in heavy soils, open forests, mixed conifer or foothill woodlands, and grasslands on clay soils.
