Globe Thistle

Direct seed outdoors in the fall for germination the following spring or sow indoors 6-8 weeks before your last spring frost date. Seeds need light to germinate so sprinkle on soil surface, firm soil and cover very lightly with soil. Germination takes 10-20 days at 20-25 degrees C.  Seedlings need room to develop so pot them on once before transplanting outside after last frost date. Prefers full to 1/2 day sun and well-drained soil. Often self-seeds in the garden. Perennial.
