Blue flax

Linum lewisii

LY-num loo-ISS-ee-eye

Blue flax is a short-lived perennial with blue-green needlelike leaves on graceful 2-foot-tall stems. Satiny sky blue flowers, borne on wiry stems, appear in late spring, last through midsummer, and open fully only on sunny days. Small rounded seed heads form in summer.

Noteworthy CharacteristicsDiscovered and documented by Meriwether Lewis, in whose honor it was named.

CareGrow in lean, well-drained soil and full sun. Cut back to sedum-like basal growth in formal plantings, or leave spent flower stems behind to blend in with a naturalistic setting.
