About

Linum (flax) is a genus of approximately 200 species in the flowering plant family Linaceae. They are native to temperate and subtropical regions of the world. The genus includes the common flax (L. usitatissimum), the bast fibre of which is used to produce linen and the seeds to produce linseed oil.

The flowers of most species are blue or yellow, rarely red, white, or pink, and some are heterostylous. There is an average of 6 to 10 seeds per boll.

How to grow it

Several flaxes are cultivated as garden ornamentals, including the blue-flowered species blue flax (L. narbonense), Lewis' blue flax (L. lewisii), and perennial blue flax (L. perenne), the red-flowered scarlet flax (L. grandiflorum), and the yellow-flowered golden flax (L. flavum). In Eurasia, since Roman times, the genus Linum has been cultivated not only for its plant fiber, but also its seeds and tender leaves for culinary usage.
