Sow outdoors in late fall/early winter. For spring planting, cold stratification is required. Start indoors in spring by placing seeds into a bag of moistened seed starting mix or wet paper towel and place it in the refrigerator for 4-8 weeks, then sow indoors and transplant after last frost.
Easily grown in average, well-drained soil in full sun. Prefers moist, rich soils.
Provide good air circulation to help reduce foliar diseases.
Pinch back stems several times before mid-July to help control plant height and encourage bushiness.
Easily grown from seed and may self-seed in the garden.
After flowering, the plant will produce seed heads containing small clusters of seed with white fluff. Since birds love to eat the seed, harvest it quickly, or cover with mesh bags. Cut or shake the mature seed heads to remove seed. Clean the seed, then store it in a cool, dry place.
