Botanical Name: Celosia argentea var. plumosa
Celosia plumosa is finally getting some of the recognition it deserves. You'll enjoy its big, bright blooms that last from spring through fall.
This compact plant is a tender perennial, typically grown as an annual in cold-winter regions. It's not likely to bloom again, so you can toss it out when it's finished blooming in fall.
You have lots of colors to choose from -- vivid shades of red, yellow, orange and pink are the most common. Many celosia varieties are available. You'll often find them for sale as Celosia Plumosa.
'Fresh Look' red celosia is a popular cultivar with big, feathery plumes.
Celosia flowers are in the Amaranthaceae family and are basically of two groups. The variety shown here is the plumosa group. It's the more popular of the two, often grown in flower beds, containers, and indoors as house plants. The second group is cristata, also known as cockscomb for its wavy crest of flowerheads.
Soft, deeply veined leaves cover the fleshy stems that hold the feathery plumes upright, above the foliage. The vibrant plumes of colors are eye-catching and look spectacular when grouped together in containers.
It is low-maintenance and easy to grow from seed. Some seeds are sold as "mixed" so you can enjoy a variety. They're also easy to find in garden centers in spring and summer.
Find a spot for celosia in a sunny window or scoot the container outdoors for show-stopping color on your porch or patio. These striking celosia flowers thrive in hot, sunny conditions.
Origin: Hybrids with parents from Asia
Height: 6 inches to 2 ft (15-60 cm)
Light: Bright light to full sun. You can grow this sun-lover on a windowsill or in a sunroom. Moving your celosia plant outdoors for the spring and summer will give it the sunlight it needs to bloom.

Humidity: Average room (around 40% relative humidity). Higher humidity levels suit this plant, if you choose to move it outdoors.

Fertilizer: Feed monthly with a high-phosphorous water-soluble fertilizer, diluted by half.
Propagation: Easy to grow from seeds. Sow celosia seeds in spring or start seeds indoors.
