Wild Blue Flax

Linum lewisii

Wild Blue Flax, also called Lewis Flax, adds elegance and movement to the garden with delicate, sky-blue flowers that bloom profusely for weeks. Each bloom lasts just a day, but the plant is rarely without color during its bloom period. Its slender stems and fine-textured foliage lend a soft, airy quality to prairie or rock garden plantings.

This drought-tolerant native is well-suited to tough, sunny sites with dry soils. Wild Blue Flax supports native bees and butterflies, and its seeds provide food for small songbirds. Though often short-lived, it reseeds lightly, helping it persist in naturalized settings.

Maintenance Tips

  • Cutback: You may cut back spent stems after flowering to neaten appearance or encourage a second light bloom.
  • Self-Seeding: Allow some seedheads to mature if you'd like it to reseed. Remove if not.
  • Division: Not necessary; this plant typically doesn’t need division.
  • Lifespan: Short-lived perennial; consider letting a few seedlings remain to maintain the population.
