EXCLUSIVE - Decorative White Blush cosmos has unique, fluted petals that form rolled, seashell-like rays around sunny-yellow centers. Their effect is three-dimensional, adding multifaceted texture to every summer bouquet. White Seashells are easy to grow and the strong stemmed plants will fill your garden with satiny 3 to 4 inch blossoms even in hot sun and poor soil. These lovely flowers dance nonstop above lacy foliage and butterflies flock to them all summer long.

Summer/fall bloom
Frost tender
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. Cover lightly and 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 ½ inch deep, keep moist and provide a good light source until ready to go outside. Plant outdoors once weather warms up after gradually acclimating seedlings to outdoor conditions.
THIN OR TRANPSLANT
When large enough to handle, space seedlings 8 inches apart.
GROWING NOTES
These long lasting, free flowering plants do well in all soil types. Sow several times through June for a succession of fresh flowers. Cutting generous bouquets actually prolongs the blooming season. Cosmos pair beautifully with cleome, asters and zinnias.
