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 snow-white flowers dance nonstop in graceful profusion above lacy foliage to beckon butterflies all summer long.

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 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 8 inches apart when seedlings are large enough to handle.

 

GROWING NOTES

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 generous bouquets actually prolongs the blooming season. Cosmos pair beautifully with cleome, asters and zinnias.
