Flax

Linum usitatissimum Linaceae Also called Linseed


The slender, graciful flax is a herbaceous annual that is cropped throughout Europe. Its seeds, known as linseed, are widely used in herbal medicine and yield a valuable oil; the fibres if its stalks are used to make linen. Flax grows to about 1 m in height and bears beautiful sky-blue flowers. The pea-sized fruits contain ten oily seeds.
