Linum lewisii (Linum perenne var. lewisii) (Lewis flax, blue flax or prairie flax) is a perennial plant in the family Linaceae, native to western North America from Alaska south to Baja California, and from the Pacific Coast east to the Mississippi River.[2] 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.[3][4][5]

It is a slender herbaceous plant growing to 80 centimetres (31 1⁄2 inches) tall, with spirally arranged narrow lanceolate leaves 1–2 cm (1⁄2–3⁄4 in) long. The flowers are pale blue or lavender to white, often veined in darker blue, with five petals 1–1.5 cm long.[5][6][7][8] The flowers open in the morning and fade, dropping their petals by noon on hot, sunny days.[9]

The plant was named for North American explorer Meriwether Lewis.[10]

Cultivation

Blue flax is a durable wildflower in garden conditions, never becoming overly aggressive towards other plants. Plants are easily grown from seed.[9] Blue flax grows well in lean soils without much organic matter and are healthier in well drained soils.[11]

  • The inflorescence is a terminal open racime.[7]

  • Flowers are pale blue or lavender to white, often veined in darker blue, with varying-length styles.[6]

  • Leaves are lanceolate, spirally arranged, 10–30 mm (0.4–1 in) long.[7]
