About Wheat cockscomb

Celosia spicata · also called Wheat cockscomb, Flamingo feather · flowering

Wheat cockscomb is a heat-loving annual producing slender, wheat-like spikes of pink, rose, or white flowers from summer to frost. Grow it in full sun with well-drained soil, water moderately, and allow the topsoil to dry between waterings. It thrives in hot weather and makes excellent fresh or dried cut flowers.

Plant type: flowering

Watch for — Aphid infestations: Soft new growth and flower buds attract aphids, causing distorted tips. Knock off with a strong water spray or apply insecticidal soap. Check undersides of leaves regularly.

The reasons wheat cockscomb isn't blooming

Almost every non-blooming wheat cockscomb traces back to one of these, roughly in order of how common they are:

  1. Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
  2. Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
  3. The plant has not been deadheaded, so it stops flowering once it sets seed.
  4. Irregular watering — drought or waterlogging at the budding stage makes buds abort.
  5. It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding wheat cockscomb a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get wheat cockscomb to flower

  1. Maximise sun. Give wheat cockscomb the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
  2. Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
  3. Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
  4. Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for wheat cockscomb and get the feeding right with the wheat cockscomb fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Wheat cockscomb flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.

For everything else this plant needs day to day, see the full wheat cockscomb care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Wheat cockscomb blooming — frequently asked questions

Why won't my wheat cockscomb flower?

Wheat cockscomb blooms on the season's growth given enough sun, warmth and the right feed — there is no cold or photoperiod trick, just good growing conditions and a bloom-leaning feed. The most common reason it is not happening: Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.

How do I make wheat cockscomb bloom?

Give wheat cockscomb the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.

When does wheat cockscomb normally bloom?

Wheat cockscomb flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

What should I do with wheat cockscomb after it flowers?

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.

What is the single biggest mistake stopping wheat cockscomb flowering?

Feeding wheat cockscomb a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.
