Celosia Flower Growing Guide: How To Plant, Grow And Care For Celosia

Celosia, with its unique, brain-like or crested blooms, might not be the first flower that springs to mind for your garden. But don’t be fooled by its slightly odd appearance! This vibrant annual boasts a range of colors, from fiery orange and magenta to sunshine yellow and cool pink. Plus, it’s surprisingly easy to cultivate, rewarding you with a burst of color that lasts from summer all the way to fall.

This guide will equip you with everything you need to know to transform your garden into a feathery paradise. So, grab your gardening gloves and get ready to witness the transformation of celosia from “feathered fury” to “feathery flair”!

Setting the Stage: Choosing Your Celosia and Location

Celosia comes in two main varieties: cockscomb celosia (Celosia cristata) with its dramatic, brain-like crest, and plumed celosia (Celosia argentea var. plumosa) with its feathery plumes that resemble wheat. Both varieties offer a spectrum of colors, so you can easily find ones that complement your existing garden palette.

Here are some popular celosia choices to consider:

  • Cockscomb Celosia: ‘Atrofasciata’ (deep red), ‘Cherry Sunrise’ (bright orange), ‘Coral Ice’ (pink and white bicolour)
  • Plumed Celosia: ‘Celestial’ (mix of colors), ‘Dracula’ (deep purple), ‘Flamingo Feather’ (hot pink)

Once you’ve picked your perfect celosia, it’s time to find the ideal spot in your garden. Remember, these heat-loving plants crave sunshine! Look for a location that receives at least six to eight hours of direct sunlight each day.

Pro Tip: Celosia thrives in hot and humid climates. If you live in a cooler region, consider planting them in raised beds or containers where the soil warms up faster.

Sowing Seeds or Starting with Transplants?

There are two main ways to cultivate celosia: starting from seeds or transplanting established seedlings.

Seed Sowing:

  • Aim to sow seeds indoors around 4-6 weeks before the last frost date in your area.
  • Use a well-draining seed starting mix and barely cover the seeds with soil.
  • Keep the soil moist but not soggy and provide plenty of warm sunlight (around 70°F).
  • Seedlings should emerge within 7-14 days.
  • Once they have two sets of true leaves, harden them off gradually before transplanting them outdoors.


  • Purchasing established seedlings from your local nursery can be a quicker option, especially for impatient gardeners.
  • Look for healthy, vibrant plants that haven’t flowered yet.
  • Harden off the seedlings for a few days before transplanting them outdoors.

Creating a Celosia Haven: Planting and Care

When the time comes to plant your celosia, be sure to choose a location with well-draining soil. Celosia dislikes soggy feet, so amending your soil with compost or organic matter can significantly improve drainage.

Planting Steps:

  1. Dig holes slightly larger than the root ball of your seedlings or transplants.
  2. Space the plants according to their variety. Cockscomb celosia requires more space (12-18 inches apart), while plumed celosia can be planted closer together (8-12 inches apart).
  3. Gently remove the seedlings from their pots or carefully loosen the soil around the roots if planting directly from the ground.
  4. Place the celosia in the hole and fill the gap with soil, ensuring the base of the plant sits at the same level as it did in the pot.
  5. Water the plants thoroughly to settle the soil.

Keeping Your Celosia Thriving: Watering, Feeding, and Maintenance

Celosia is a relatively low-maintenance plant, but a few key practices will ensure it thrives and produces an abundance of blooms.


  • Water your celosia regularly, allowing the top inch of soil to dry out between waterings.
  • Avoid overwatering, as this can lead to root rot.
  • Deep watering less frequently is better than shallow watering more often.


  • Celosia doesn’t require heavy feeding. A balanced fertilizer applied once a month during the growing season is sufficient.
  • You can also use a water-soluble fertilizer for a quick boost.
  • Stop fertilizing once the celosia starts flowering.


  • Deadheading, or removing spent flowers, will encourage your celosia to produce even more blooms throughout the season. Simply pinch off the faded flowers at the base of the stem.

Pests and Diseases:

  • Celosia is generally resistant to most pests and diseases. However, keep an eye out for aphids, which can be controlled with insecticidal soap spray.
  • Fungal diseases like powdery mildew can occur in humid conditions. Ensure good air circulation around your plants and avoid overwatering to prevent this.

Enjoying Your Celosia Creation:

With proper care, your celosia should reward you with a vibrant display of color for months. The long-lasting blooms also make excellent cut flowers. To harvest them for indoor arrangements, simply cut the stems at an angle just below a flower head when the blooms are fully formed but haven’t started to fade.

Celosia can also be dried for everlasting enjoyment. To do this, cut the stems when the flowers are almost fully open and hang them upside down in a cool, dark, well-ventilated area. After a few weeks, the flowers will be dry and ready to use in potpourri or decorative arrangements.

Beyond Summer: Can Celosia Survive Winter?

While celosia is typically treated as an annual, it can act as a tender perennial in warmer climates (USDA hardiness zones 10 and 11). If you live in these regions, you can attempt to overwinter your celosia plants.

Here’s how:

  • Before the first frost, cut back the stems by about half.
  • Carefully dig up the plants and repot them in containers filled with well-draining potting mix.
  • Place the potted celosia in a sunny location indoors where the temperature stays between 50-60°F.
  • Water sparingly throughout the winter, just enough to prevent the soil from drying out completely.
  • In spring, once the danger of frost has passed, gradually harden off the plants and replant them outdoors in a sunny spot.

With a little extra care, you can enjoy your celosia for multiple seasons!


Celosia, with its unique charm and vibrant colors, is a fantastic addition to any garden. Now that you’re armed with this comprehensive guide, you have everything you need to cultivate a thriving display of these fascinating flowers. So, embrace the “feathery flair” of celosia and watch your garden transform into a dazzling spectacle of summer color!
