Direct sow after the last frost or in late fall where winters are mild. Choose a sunny site with loose, well-draining soil. For earlier blooms, start indoors 4–6 weeks before the last frost and transplant carefully once hardened off.

Sow seeds 1/4 inch deep and thin seedlings to 8–12 inches apart for sturdy plants and plentiful stems. Keep soil evenly moist during establishment, then water moderately. Pinch young plants to encourage branching and more flower production.

Cut flowers when petals are just opening for longest vase life. Deadhead or harvest frequently to promote continuous bloom. Allow a few heads to mature if you’d like self-seeding for future displays.
