Linum lewisii Linum lewisii 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 (USDA Plant Profile: "Linum lewisii"). It grows on ridges and dry slopes, from sea level in the north up to in the Sierra Nevada. It is a slender herbaceous plant growing to 80 cm tall, with spirally arranged narrow lanceolate leaves 1–2 cm long. The flowers are pale blue or lavender to white, often veined in
Flax for nine months at room temperature, and under warehouse conditions, for 20 months at ambient temperatures. Three natural phenolic glucosides—secoisolariciresinol diglucoside, p-coumaric acid glucoside, and ferulic acid glucoside—can be found in commercial breads containing flaxseed. Flax fiber is extracted from the bast beneath the surface of the stem of the flax plant. Flax fiber is soft, lustrous, and flexible; bundles of fiber have the appearance of blonde hair, hence the description "flaxen" hair. It is stronger than cotton fiber, but less elastic. The best grades are used for linen fabrics such as damasks, lace, and sheeting. Coarser grades are used
