Celosia can bloom from June until frost. During that time, deadheading your Celosia will encourage new blooms. Remove the flowers as they start to turn brown and lose color. If you wait too long after this point, seed development starts and the plant puts its energy into that rather than new blooms. Deadheading is not necessary in fall, as the plant is not likely to bloom again.

Celosia plants are tender perennials (in Zones 10-12) grown as annuals. Their inflorescences are brightly colored in showy colors of red, purple, pink, orange and yellow. The name celosia is derived from the Greek kelos, "burnt," referring to the flowers' fiery colors and often flamelike shape.

Although 50-60 varieties exist, commonly planted varieties belong to two species, Celosia argentea and Celosia spicata. Two forms of C. argentea are popular: the Cristata varieties (cockscomb) bear rounded, crested flower heads resembling enormous rooster combs or a cauliflower shape, and Plumosa varieties feature erect, featherlike plumes.

Deeringia spicata syn.Celosia spicata (spiked cockscomb) is also known as wheat celosia for its narrow, spiky flower heads, reminiscent of the heads of wheat. These plants produce numerous flowers, with an almost shrubby look.

Celosias make good cut or dried flowers. To dry, cut stems of full blooms at peak, and remove all the leaves, wrap a rubber band around 6-8 cut stems and hang them upside down from a coat hanger in a dark, cool, dry, airy space for several weeks or until fully dried. They will last in dried arrangements for at least six months without losing any of their vibrancy.
