Delphinium - Tall Mix Seeds

  • Start delphinium seeds indoors 8-10 weeks prior to your last frost date. Can also direct-seed in fall.

    Cold stratification will improve germination. Place seeds in a moist paper towel inside a plastic bag or container. Keep in the fridge for 1-2 weeks before seeding.

    Press seeds into soil and cover lightly. Keep moist until germination in ~14-30 days (may be longer with cooler temperatures).

    Transplant after your last frost date into a sunny location, with plants 12-18 inches (30-45 cm) apart.

  •  Delphinium elatum

    Also known as perennial larkspur, lark's heel, knigh's spur
