Seeds need light to germinate so sprinkle on soil surface, firm soil and cover very lightly with soil. Germination takes 10-20 daysat 20-25 degreesC. Seedlings need room to develop so pot them on once before transplanting outside after last frost date. Prefers full to1/2 daysun andwell-drainedsoil. Oftenself-seedsin the garden.Perennial.
