Q. Should I cut off the dead flowers of my celosia?

Answer

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 loose 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 are tender perennials (in Zones 10-12) grown as annuals. Their inflorescences are brightly colored and showy--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 even cauliflower. Plumosa varieties feature erect, featherlike plumes. C. spicata, spiked cockscomb, is also known as wheat celosia for its narrow, spiky flower heads, reminiscent of heads of wheat. These plants produce numerous flowers, with an almost shrubby look.

Celosias make good cut or dried flowers. To dry, remove all the leaves from the stems and wrap a rubber band around 6-8 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.

  1. I have them multiplying all over the place. I have taken a few from one pot and transplanted to 2 other pots and they multiply again. From one pot with a dozen to 3 pots. They just keep going. Wish I had a garden to put them in. 😀

  2. I wish I could make mine happy. I have now cut it back due to it looking like limp celery. Will it come back? It was such a pretty yellow:orange color.

  3. The limp look is a result of too much water at the roots of the plant, typically as a result of soil that doesn't drain quickly enough for the plant.

    Some celsoia can bloom into the fall. Early in the season you can pinch back plants for bushier growth, but once it has begun to flower, it is best to just deadhead to encourage new blooms. The growing environment has to be improved first for the plant to have blooming longevity.
