Lewis flax is a graceful native perennial wildflower with brilliant blue blooms, widely distributed across western North America from Alaska to Arizona. It is easy to grow in well-drained soils and tolerates a range of conditions once established, making it an excellent low-maintenance choice for native meadow gardens and pollinator plantings. Sow seeds in fall or early spring for best germination results, and avoid heavy clay soils to keep plants thriving.
