Blue flax (Linum lewisii)
LY-num loo-ISS-ee-eye
Synonyms:  Linum perenne ssp. lewisii
Genus:  Linum
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 mid-summer, and open fully only on sunny days. Small rounded seedheads form in summer. 
Noteworthy Characteristics:  Discovered and documented by Meriwether Lewis, in whose honor it was named.
Care:  Grow 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.
Propagation:  Sow seed in spring or autumn.
Problems:  Stem rot, rust, wilt, anthracnose, damping off, slugs, snails, and aphids.
