Sea Shells Mix cosmos is known for its unusual tubular petals, rolled like tiny seashells around golden centers. Blooms appear in shades of pink, rose, white, and crimson, floating over fine, ferny foliage and tall, airy stems that make the whole planting feel loose, bright, and full of movement.

This is an easy, generous annual for cutting gardens, pollinator patches, and open sunny beds. The flowers are light enough for meadow-style plantings but distinct enough to make people pause—the kind of cosmos that brings a little surprise to every bouquet.

Every order is packed with care by our small team in Pennsylvania and typically ships within 2–3 business days—often by the next business day. We ship throughout the United States using USPS and UPS.

Plant seeds directly in the garden after average last frost date. Optimum soil temperature for seed germination is 60-70°f. Or, start seed indoors 4-6 weeks before transplanting into the garden. Transplant to the garden 1-2 weeks after your average last frost date. Removing old blossoms will encourage new growth. Plant staking may be required for added support. Great for cutting, beds and borders, and the pollinator garden. Prefers well-draining soils.
