Description:

Cosmos is an easy-care, drought-tolerant annual, which flowers prolifically. Its red, pink, or white daisy-like flowers with yellow centers bloom June to frost. Taller varieties should be staked for support when flowering. Deadhead to prolong blooming, but leave some spent flowers in the fall to provide seeds for the birds. This plant will self-seed, sometimes aggressively. Excellent choice for beds, borders, and cutting gardens.
