This clump-forming perennial features clusters of blue to blue-violet, three-petaled flowers accented by contrasting yellow stamens. Flowers open a few at a time, each one lasting for one day. Found growing naturally in the sandy soil of the eastern plains and lower foothills. Will take sun or light shade. A long-flowering period of bloom occurs during May – August depending on elevation. Young shoots should be protected from slugs and snails. Self-seeds readily. Deer resistant, special value to native bees.
