Cosmos is a very easy to grow annual producing flowers in shades of white, pink and deep crimson. The foliage is feathery and fernlike in appearance. It will bloom all summer until frost. Attractive to butterflies. Plant in full sun in poor to average well-drained soil. Avoid heavy clay. Do not fertilize as rich fertile soil tends to produce tall lanky plants with few flowers. Grows to a height of 4-6 ft.
