The flowers are pale blue or lavender to white, often veined in darker blue, with five petals 1–1.5 cm long and in varying length styles.[2][3][4][5] The flowers open in the morning and fade, dropping their petals by noon on hot, sunny days.[6]

Etymology

The species was named for North American explorer Meriwether Lewis.[7]

Distribution and habitat

The plant is native to western North America from Alaska south to Baja California, and from the Pacific Coast east to the Mississippi River.[8] It grows on ridges and dry slopes, from sea level in the north up to 11,000 feet (3,400 metres) in the Sierra Nevada.[9][10][2]

Cultivation

Blue flax is a durable wildflower in garden conditions, never becoming overly aggressive towards other plants. Plants are easily grown from seed.[6] Blue flax grows well in lean soils without much organic matter and are healthier in well-drained soils.[11]
