TO PLANT OUTDOORS 
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 moist. Seedlings emerge in 7 to 10 days. Keep well weeded and watered while plants are young; mature cosmos can handle hot and dry conditions.

TO START EARLY INDOORS 
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. Plant outdoors once weather warms up after gradually acclimating to outdoor conditions.

THIN OR TRANSPLANT
Space 6 inches apart when seedlings are large enough to handle.

GROWING NOTES 
These free flowering summer bloomers produce reliably in all soil types and can be sown several times through early July for a succession of flowers. Cutting generous bouquets actually prolongs the blooming season. Replant a spent spring flower bed with satiny Snow Sonata, deep indigo Royal Ensign bush morning glories and sparkling Signet Marigolds for a summer showing to shine until frost.
