Exploring Celosia Varieties (Cockscomb)

The low-maintenance, high-impact celosia plant belongs to the Amaranthaceae family. Celosia is one of the most eye-catching flowering plants because of its 3 distinct shapes. There are three types of celosia: plumed, wheat, and cockscomb.

  • Plumed varieties (celosia plumosa) have multiple flower stalks and blooms with a feathery appearance. They are often between 8 and 24 inches tall.
  • Wheat varieties have a singular flower stalk and look similar to the head of a grain crop. These are often between 12 and 36 inches tall and are the most limited in colors compared to the plumed and cockscomb varieties.
  • Cockscomb or crested varieties (brain flowers) have coral or brain-looking blooms that are often large and heavy so they must often be staked. They grow between 12 and 36 inches tall.

Comprehensive Guide to Celosia Plant Care: Planting Watering, Sunlight, and Fertilization Tips

Gorgeous Celosia has a USDA hardiness zone of 10-11 so it is generally treated as an annual. However, in zones 9 to 11 celosia might surprise you by acting like a short-lived perennial. From my experience, and I’m in gardening zone 6a, this easy-care annual drops seed, self-sows, and returns yearly.

Which is a lovely treat! When we first moved here, I had no idea it was planted in years prior. So imagine my surprise as it emerged that first summer and leveled up my garden with its gorgeous flowers.

In order to thrive, Celosia flower needs 6-8 hours of full sun per day and should be planted in well-draining soil. Flowers appear beginning in early to mid-summer and the blooms continue through to fall.

  • Plant these flowering annuals after all danger of frost passes in well-draining soil that is rich in organic matter.
  • Deeply water the base of plants in the earlier part of the day. In the heat of summer, you’ll likely be watering it daily to keep the plant hydrated during extreme heat.
  • Fertilize with a well-balanced fertilizer. I prefer to use a slow-release fertilizer when I plant so it is set and forget.
  • Deadhead spent blooms and cut flowers so your celosia plant produces more flowers until the first frost.
  • Pests and diseases are usually not a problem with this hardy plant, but occasionally issues with snails and slugs can occur. Celosia plants can be susceptible to root rot which can easily be prevented by growing the plant in well-drained soil.

Step-by-Step Guide: Starting Celosia From Seed Successfully

Starting your celosia plants from seed is a rewarding and cost-effective way to fill your garden with vibrant blooms. This step-by-step guide will take you through the essentials of sowing celosia seeds both indoors and outside, ensuring optimal germination and strong, healthy seedlings.

Whether you’re a beginner gardener or looking to expand your existing floral collection, learning to start celosia from seed opens up a world of colorful possibilities for your garden beds and containers. Let’s chat about the process of nurturing these striking flowers right from the very start.

How to Sow Celosia Seeds Indoors: Tips for Effective Germination

  • Gather seed starting supplies. If you don’t have a greenhouse, find a location in your home where can spare the space.
  • Start seeds indoors before the last frost date. Follow your seed packet directions for how many weeks before to sow them.
  • Fill each of the cells or pots with pre-moistened seed starting soil. Pack it down to remove any air bubbles and gaps.
  • Sow seeds according to seed packet directions. As a general rule, plant seeds twice their depth. Celosia seed is pretty small so I drop some on top of premoistened soil and cover with lightly vermiculite. (Note: Make sure you sow only one type of seed variety per tray because they germinate at different rates.)
  • Drop 1-2 colosia seeds per cell and cover with vermiculite until the tray is full. It’s OK to cover with seed-starting soil, but vermiculite is easier for seedlings to grow through.
  • Label your seed trays and/or individual pots. Cover seed trays with a clear plastic dome. Place trays on heat mats under grow lights.
  • Set lights to be on for 14-16 hours per day. Using a timer works best for this.

Best Practices for Caring for Celosia Seedlings: Ensuring Healthy Growth

  • Check seedlings daily for germination. Usually takes about a week or so.
  • When seeds begin to sprout, uncover and remove from heat mats. Don’t worry if they didn’t all sprout because more will germinate after the dome is removed.
  • Place trays under the lights about an inch or so away from the tallest seedling. Keep an eye on seedling growth as you will need to adjust the lights as they grow.
  • Always water from the bottom. If the seeds aren’t in a tray that has a water reservoir, sit them in a tray of water for about an hour so they can soak it up from the roots.
  • After germination, take care of seedlings making sure they are not overwatered.
  • Celosia seedlings can be susceptible to dampening off so let the soil dry out slightly between waterings.
  • Harden off and transplant outside when temperatures after all danger of frost has passed.

Direct Sowing Celosia Seeds in Your Cut Flower Garden

While you can sow celosia seeds indoors, it works equally as well if you directly sow them in the garden too. Simply follow your seed packet directions for when to sow them and plant accordingly.

In my zone 6b garden, celosia grows with ease, so either method works well.

Celosia FAQs: Answers to Your Most Common Questions About Growing and Caring for Celosia

Cultivating these stunning blooms might raise questions, especially for beginners. In this section, I’ll address some frequently asked questions about growing celosia, providing you with insights and tips to nurture these remarkable plants with confidence.

Does celosia plant spread?

Celosia flower is known to exhibit some degree of reseeding in the right conditions. Here’s what you need to know:

  • Seeds: As celosia plants mature and produce blooms, they also produce seeds. These seeds can fall to the ground or be carried by the wind.
  • Self-Sowing: In some cases, celosia seeds that fall to the ground can germinate and grow into new plants on their own. This is known as self-sowing or natural reseeding.
  • Climate Consideration: The likelihood of celosia reseeding can depend on your climate and growing conditions.

While celosia’s reseeding potential can be a wonderful surprise, you may want to manage it to maintain a well-organized garden:

  • Selective Deadheading: If you want to encourage reseeding, leave some spent blooms on the plant to allow them to go to seed. However, if you want to control reseeding, deadhead the flowers before they form seeds.
  • Seed Collection: If you’d like to have more control over where and when celosia reseeds, you can collect the seeds from mature blooms and store them for intentional sowing in the next growing season.

Can celosias grow all year round?

These easy-to-grow flowering annuals are hardier in zones 10-11. Celosia plant flowers from mid-summer until the first frost in fall.

How do you keep celosias blooming?

To make the most of celosia’s summer blooms and extend its flowering performance, follow these tips:

  • Location: A sunny, dry,  and warm location will keep celosia healthy and blooming.
  • Deadheading: Regularly deadhead spent flowers to encourage the plant to keep producing new blooms.
  • Fertilizing: Providing a balanced fertilizer during the growing season can help sustain the blooming period. I like to use a slow-release fertilizer like this.
  • Watering: Consistent watering without overwatering will keep celosia hydrated and blooming. Only water when the top 1-2 inches of soil are dry.

Is celosia toxic to dogs?

Celosias are not poisonous to cats, dogs or humans. The plants can be kept in any home without any problems. In some regions, celosia is even used in medicine and cooking.

How do I propagate celosia?

Celosia is best propagated from seed. I like to start seed indoors to get a jump on the season, But the seeds can also be directly sown after all danger of frost passes and the soil temperature is at least 60 degrees.

How do I dry celosia?

Celosia is easy to dry and looks gorgeous after it does. Cut the flowers when they are fully developed in the early part of the day after the dew has dried.

For dried arrangements, remove all the leaves from the stems, wrap a rubber band around six to eight stems, and hang them upside down 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.

Can celosia be grown in a container?

Growing celosia in containers is a brilliant solution for those who are short on garden space or are just beginning their gardening journey.

These vibrant blooms, with their striking plumes that come in an array of colors, bring a burst of life to any corner, deck, balcony, patio, porch, or other outdoor living space.

Celosia’s compact size and relatively low maintenance needs make it a perfect choice for container gardening. Their adaptability to small spaces allows urban gardeners to infuse color and charm into their surroundings, even without a traditional garden bed.

With well-draining soil, a sunny spot, and occasional watering, celosia can thrive in containers, adding a touch of whimsy and nature to any nook with minimal effort.

They make beautiful container plantings both on their own when combined with other plants that like the same sunny growing conditions. Celosia is a must-have plant in summer or fall plantings.

  1. This is the first year that I’ve grown celosia. I just love it and it is an amazing cut flowers. Mine are actually in my cut garden but next year I will put them in my regular beds for more interest and color. Hopefully the deer won’t like them 🙂

  2. Hi

    Thank you for all your posts!

    I’m wondering if you think the plant water globes are a good option if one is out of town for a week. If so, is there one that is better than the rest. I’m worried about my outside containers with flowers.

    Thanks,
    Lisa
