The exotic Cosmos (Cosmos bipinnatus), a native of Mexico, is a quick-blooming annual that created brilliant colors of white, pink and crimson. Plants usually have a long blooming period. Leaves are dissected and thread-like. Seeds should be sown in the spring or early summer. Plants are not winter hardy and need replanting each spring for continued success. Plants tend to grow taller in rich, fertile soil. Reseeds well. (Note: fall planting of this exotic garden variety is discouraged in regions where frost/freeze is probable. Spring and summer sowing is recommended.)
Often used to create large masses of fall color for weddings or other celebrations. Easy to grow and best color comes if summer planted for a fall bloom. As temperature starts cooling down, colors become brilliant and blooms are covering most of the plant perimeter making a great show.
