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.
Description
It is a slender herbaceous plant growing to 80 centimetres (31+1⁄2 inches) tall, with spirally arranged narrow lanceolate leaves 1โ3 cm (1⁄2โ1+1⁄4 in) long. The flowers are pale blue or lavender to white, often veined in darker blue, with five petals 1โ1.5 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]
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]
