Personal notes - Sea holly has a long tap root, which makes transplanting difficult. Place seedlings in their permanent location.
Root cuttings can be taken in autumn or winter.
Seed can be sown when it ripens in early autumn. They do best if placed on the surface of well-drained compost in a cold frame. Seed can germinate in as little as five days or as long as ninety days. Seedlings should be set out the following spring after the last frost.
