Double Click Cosmos is a ruffled, full-petaled flower that blooms from early summer straight through fall in zones 2 to 11. These compact plants reach 36 to 48 inches tall and flower within 75 days of sowing, filling your garden with rose-hued, mostly doubled blooms that look almost too intricate to be real. Open-pollinated and drought-tolerant, they thrive on neglect and minimal water once established, making them a low-fuss option for busy gardeners and an exceptional choice for cutting.

The ruffled, doubled blooms on these tall stems command attention from up close, with petals so intricately layered they practically invite you to reach out and touch them. A single patch creates an earthbound constellation of color, drawing in bees, hummingbirds, and butterflies from June through November. These flowers are built for cutting, and harvesting bouquets actually prolongs the blooming season rather than slowing it down.
Double Click Cosmos are excellent cut flowers. Harvest blooms in the early morning when petals are just opening, cutting with a clean knife dipped in a 10% bleach solution. A few drops of bleach in the vase water will extend their vase life. The prolonged blooming season makes them especially valuable for fresh flower arrangements throughout summer and fall.

Sow seeds indoors 4 to 6 weeks before your last spring frost in seed-starting mix. Cover seeds lightly at a depth of 1/8 to 1/4 inch, and maintain soil temperatures between 60 and 75°F. Seeds will sprout in 3 to 10 days. Provide good light once seedlings emerge. Harden off seedlings gradually before transplanting outdoors after all danger of frost has passed.
Transplant seedlings outdoors after the last spring frost once soil temperature is consistently above 60°F. Space plants 6 inches apart. Harden off plants by gradually acclimating them to outdoor conditions before planting.
Direct sow seeds in spring after the last frost date, once soil temperature is above 60°F. Cover seeds lightly and keep soil moist until germination occurs. For a succession of blooms, sow multiple times through June.
Cut flowers in the early morning when they are at their freshest and petals are just opening but not yet flattened. Use a clean knife dipped in a 10% household bleach solution to harvest. Remove generous bouquets regularly; cutting actually prolongs the blooming season.
Pinching young plants encourages branching and creates fuller, bushier growth. Deadheading is essential throughout the growing season to promote continuous blooming into fall.
