Celosia cristata, commonly known as cockscomb is an annual plant cultivated around the world for its large, bright colored, cauliflower-shaped flowers, which resembles a velvety rooster’s comb. The flowers come in a wide variety of colors from purple, pinks and violet to orange, red and crimson. In Guangzhou, China, it is listed among the favorite plants grown in pots by people living in house boats and the bright red color of some plants makes it a common sight in Chinese new years celebrations.

A tropical native, cockscomb thrives in hot weather if planted in moist, well-drained soil and does well in containers or sunny borders. The plant grows up to 3 feet tall, with large flower stalks blooming from July to October. It is often grown in greenhouses and forced to bloom earlier for new years celebrations in spring. The plant is grown easily in average garden soil and does best in full sun or light shade, with adequate water and warmth.
