The genus Linum is comprised of annuals, biennials, perennials, shrubs, and subshrubs in 200 species grown for their colorful 5-petaled flowers, most often in shades of blue, yellow, or white. Use smaller species in a rock garden and larger ones in a border. Annual species make good filler plants.
CareGrow in a light, organically rich, well-drained soil in full sun, with protection from winter moisture. Some species are short-lived.
PropagationSow annual seeds where they are to grow in the garden, and sow seeds of perennial and shrubs in a cold frame, all in spring or autumn. Perennials can also be propagated from stem-tip cuttings in early summer. Take semi-ripe cuttings of sub/shrubs in summer.
ProblemsStem rot, rust, wilt, anthracnose, damping off, slugs, snails, and aphids.
