Bright and bold, cockscomb (Celosia argenta) blooms from summer until early fall. The convoluted flower heads have a shape similar to cauliflower. These annual flowers look garish in the wrong setting, so plan your companion plants carefully. They make excellent cut flowers that last a long time in the vase. They also dry well and can be used in crafts. Cleosia self-seeds readily. The seeds that fall in autumn germinate in spring or summer, when the soil warms.
