Start Globe Thistle seeds indoors 6-8 weeks before your last frost date, or direct-seed them outdoors in the fall. For indoor planting, cold stratification can improve germination: place seeds in a moist paper towel inside a plastic bag or container, and refrigerate for 2-3 weeks before planting. (Cold stratification is not necessary for fall-sown seeds.)

Press seeds lightly into the soil and cover, as they need some light for germination. Keep the soil consistently moist until germination, which typically occurs in 14-21 days, though cooler temperatures may delay it.

After the last frost, transplant seedlings to a full sun location, spacing plants 18-24 inches (45-60 cm) apart.
