Linum, the classical name of flax, and the botanical name of a genus of which that is the most important member (see Flax), containing several species cultivated as garden plants, both annual and perennial, not mentioned under that title. L. grandiflorum is a very showy annual from Algiers; the plant is much branching, about 18 in. high, and bears a profusion of brilliant scarlet flowers, shaded with crimson toward the centre, and over an inch in diameter; the plant rarely produces seed in this country. Among the perennial species none is more graceful than L. perenne of Missouri and westward; this, known in our gardens as perennial flax, forms tufts of slender stems 12 to 18 in. high, which produce an abundance of bright blue flowers an inch in diameter, upon such delicate flower stalks that at a little distance they seem to be floating without any support; there is a white variety of this in cultivation. Berlandier's flax (L. Ber-landieri) is a fine yellow-flowered species in Texas; and similar to it is L. flavum, a common greenhouse species with yellow flowers.

They all grow readily from seed.
