Linum lewisii

Blue Flax
Linaceae
Perennials, Flowers

LINUM

Plants with erect, branching stems and narrow leaves produce an abundance of shallow-cupped, five-petaled flowers over a long bloom period. Each bloom lasts only a day, but others keep coming. The flax of commerce—Linum usitatissimum—is grown for its fiber and seeds, which yield linseed oil.

Use in borders; some naturalize freely in uncultivated areas. Light, well-drained soil. Most perennial kinds live only 3 or 4 years and should be replaced regularly. Easy to grow from seed; perennials also can be propagated from cuttings. Difficult to divide.
