Common Flax

<em>Linum usitatissimum</em> is an annual flowering plant in the family Linaceae, order Malpighiales, commonly known as common flax or linseed. This species has been cultivated by humans for thousands of years and is one of the oldest domesticated crops, valued for both its fiber (used to produce linen textiles) and its seeds (source of linseed oil and dietary flaxseed). <em>Linum usitatissimum</em> has an exceptionally broad global distribution through cultivation and naturalization, with presence documented across Africa, Asia, Europe, North America, Oceania, and South America. The plant typically grows as a slender, erect annual reaching approximately 1.2 meters in height, bearing narrow leaves and distinctive pale blue to white five-petaled flowers. It favors well-drained soils in temperate to subtropical climates and is widely grown as a commercial crop. The species thrives in open, sunny habitats. Biological traits of this species remain poorly documented in the scientific literature.
