What Is a Cockscomb Flower?

Plume Cockscomb

• Also known as woolflower or feathered amaranth, plume cockscomb (Celosia argentea var plumosa) displays light, feathery, flamed-shaped blooms that resemble velvety masses of tangled yarn. Plume cockscomb is available in a number of varieties, including Celosia "Century," a series of 2-foot plants with large blooms. Dwarf varieties include Celosia "Geisha," which reaches 8 to 10 inches and "Fairy Fountains," at 12 inches. "Celosia "Kimono" is a petite dwarf series that tops out at 4 to 6 inches. All are perennial in USDA zones 10 through 12, and all are available in a variety of bright colors.

Crested Cockscomb

• Crested cockscomb (Celosia argentea var cristata) displays light, dense blooms in contorted fan shapes. Varieties include Celosia "Chief," a series of impressive plants that reach heights of 3 to 4 feet, and Celosia "Sparkler," a slightly smaller series that grows to about 2 1/2 feet. Dwarf varieties that top out at 6 to 8 inches include Celosia "Jewel Box," and Celosia "Amigo," both available in a variety of vivid colors. Crested cockscomb, most often grown as an annual, is perennial in USDA zones 10 through 12.

Uses

• A nearly indestructible plant, sturdy cockscomb flowers withstand rains, storms and harsh winds without wilting or fading. The plant is at home in flower beds, and the bright colors are especially impressive in mass plantings. Cockscomb grows well in containers either indoors or outdoors as long as it receives at least eight to 10 hours of bright, direct sunlight per day. The flowers are interesting additions to cut flower arrangements and dry easily by hanging them upside down in a cool, dark, well-ventilated space.

Growing Conditions

• Cockscomb is a non-fussy, easy-to-grow plant that thrives in warm, humid weather and displays stunted growth when temperatures fall below 60 degrees Fahrenheit. Although cockscomb tolerates light shade, it produces the best blooms in full sunlight. Similarly, cockscomb isn't choosy about soil and tolerates even poor, heavy clay soil. However, the plant performs best in average, slightly acidic garden soil with a pH between 6.0 and 7.0. Cockscomb prefers moist soil and may not bloom in periods of drought. However, the plant is prone to fungal disease in overwatered, soggy soil.
