Celosias (Celiosa spp.), commonly called cockscomb, feathered amaranth, woolflower and red fox, are warm-weather flowering plants that thrive in hot, humid Mediterranean areas. They are commonly grown as annuals but can survive winters in U.S. Department of Agriculture plant hardiness zones 10 and 11. Mature plant height is generally between 6 inches and 3 feet, depending on the cultivar. Celosias in the “Childsii” and “Cristata” groups have rounded flowers, those in the “Plumosa” group have arrowhead-shaped flowers and those in the “Spicata” group have bottle-brush type flowers. They are all easy to care for as long as their soil and sunlight requirements are met.
