How to grow:

Sow directly into full sun after the last frost, using fertile, well-drained soil. For best results, sow three times the number of plants you want (e.g., 6 seeds for 2 strong plants) at 5 mm–1 cm (¼–½ in) depth. Space seedlings 0.75–1 m (2–3 ft) apart and thin to strongest stalks. Let the flowers follow the sun, attract pollinators, and produce delicious seeds for both you and the birds.
