Start indoors 10-12 weeks before last frost. Sow seeds thinly on soil surface and gently press seed into soil. Do not cover with soil as seeds require light to germinate. Bottom water of lightly mist to keep soil evenly moist. Transplant seedlings to cell packs or larger containers when the first true leaves appear, usually 3-4 weeks after sowing. Plant outdoors into rich, well-drained soil after last frost. Space plants 20-30cm apart in partial to full sun. Harvest for cut flowers when the lower 1/2 to 1/3 of the flowers on the spike are open. Annual
