Days to Germination:20-25 days
Linum perenne lewisii. Blue Flax should be direct-sown outside as soon as the ground can be worked in the spring. Or, as you plant fall flower bulbs, direct-sow it for spring germination. Prepare a bed in full to partial sunlight with rich, well-draining soil. Sow seeds on top of soil, leaving the seeds uncovered but pressed firmly onto the soil surface, as light aids germination. Flax may also be started indoors 6 to 8 weeks before transplanting out after the threat of spring frost has passed. Use individual peat pots or seed starting cells to avoid root disturbance. Provide even moisture and strong light. Harden off the seedlings by gradually acclimating them to the outdoors over 1 to 2 weeks before transplanting out. Naturalizing Blue Flax is loved for its vivid, cornflower-blue, saucer-shaped flowers. It may bloom the first year if started early enough in the spring. Summer flowering. Height: 12" to 24".
