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.3
