Start Giant Hyssop seeds indoors 8-10 weeks before your last frost date. To improve germination, cold stratify the seeds by placing them in a moist paper towel inside a plastic bag or container, then refrigerate for 2-3 weeks before sowing.

Press seeds lightly into the soil and cover, keeping the soil consistently moist until germination, which usually occurs in 14-21 days. After the risk of frost has passed, transplant seedlings to a sunny location, spacing plants 12-18 inches (30-45 cm) apart.
