Lewis’ Flax

Linum lewisii Pursh

Perhaps the best known and toughest of the western wildflowers, this is the lovely blue flower seeded along roadsides. It is extremely prolific and drought tolerant. Flax blooms primarily in the early summer and then sheds seeds for the rest of the growing season. Sufficient moisture will prolong flowering or even restart flowering late in the summer. It can become a garden pest but can be a great addition to less-cultivated areas, such as open spaces and roadsides. Cutting back plants by about half after flowering can help control reseeding.
