Homeowner Growing Tips: Grow in full sun or partial shade, in well-drained soil. Amend with compost before planting. Should be planted after the last frost date. Prefers not to dry out, but is somewhat drought tolerant once established. Avoid overcrowding, as these like good air circulation. Deadhead throughout the season to encourage rebloom; leave the final spent flower stalks on the plant in autumn, as the seeds will feed the birds; cut back in late winter. Divide in spring, if desired. May be a short-lived perennial, but often freely re-seeds.
