Sow seeds 1/2 inch deep, 1 to 2 inches apart in a sunny location in well-worked garden soil once danger of frost is past. Keep seed bed evenly moist; seedlings emerge in 7 to 10 days. Thin established seedlings to a final spacing of 8 inches apart, so plants have room to mature. Keep well weeded and watered while plants are young; mature cosmos can handle hot and dry conditions, but bloom longest if regularly watered.


Sow seeds 1 inch apart in a container of seed starting mix, 4 to 6 weeks before last expected frost. Cover 1/2 inch deep, keep moist and provide a good light source until ready to go outside. Plant outdoors 8 inches apart once weather warms up, after gradually acclimating seedlings to outdoor conditions.


These free-flowering, long blooming summer flowers produce reliably in all soil types to fill the garden with abundant blossoms. Sow several times through June for a succession of fresh flowers. Cutting stems of flowers regularly actually prolongs the blooming season. Stunning Rose Bon Bon makes beautiful and long-lasting bouquets and pairs easily with other garden flowers.
