Graceful, vibrant, and unique: The Cosmos Seashells Mix features delicate, ruffled blooms in shades of pink, red, and white that resemble seashells, adding a whimsical touch to any garden. Known for their light, airy growth habit and attractive foliage, these plants are perfect for borders, meadows, or containers. They also attract pollinators and make beautiful cut flowers.

Direct Sowing: Sow seeds directly in well-drained, fertile soil after the last frost date, once the soil temperature has reached at least 55°F. Scatter the seeds evenly over the soil and lightly press them in. Water gently to keep the soil moist during the germination process, which typically takes 7–14 days. Once seedlings are established, thin them to 10–12 inches apart to provide space for the plants to grow and flourish.

Early Sowing for Seedlings: Start seeds indoors 6–8 weeks before the last expected frost date. Use seed trays filled with a light, well-draining potting mix, and maintain a temperature of 70°F for optimal germination. Once seedlings are strong and the outdoor conditions are warm enough, harden them off and transplant them to the garden. Space them 10–12 inches apart to ensure they have ample room for healthy growth.

Harvesting: Cosmos flowers are ready to harvest when the blooms are fully open and colorful. Cut the stems early in the morning when the flowers are cool and fresh. These flowers are great for fresh bouquets or dried by hanging them upside down in a cool, dry place. Regularly remove spent blooms to encourage more flowers throughout the season.
