Celosia argentea

Celosia argentea, commonly known as plumed cockscomb, or the silver cock's comb, is a herbaceous plant of tropical origin, and is known for its very bright colors. In India and China it is known as a troublesome weed.
Celosia argentea is a tender annual that is often grown in gardens. It blooms in mid-spring to summer. It is propagated by seeds. The seeds are extremely small, up to 43,000 seeds per ounce. The flowers are hermaphrodites.
As these plants are of tropical origin, they grow best in full sunlight and should be placed in a well drained area. The flowerheads can last up to 8 weeks, and further growth can be promoted by removing dead flowers.'=

Celosia argentea var. cristata 'Flamingo Feathers' is a cultivar that can grow up to 2 feet in height. The colors are predominantly pink to light violet, and the leaves are a darker green than other cultivars. The Century cultivars are usually taller (1–2 feet), and are bright red, yellow, orange, or pink. The Kimono cultivars are generally smaller (4 inches - 1 foot), and have more muted colors, though similar to the Century cultivars. Other colors, such as white, burgundy, orange-red, etc., can be found. Certain varieties will grow to 3–4 feet in height.[4] Celosia plumosa, also known as Prince of Wales Feathers, is a synonym for Celosia argentea. Often sold as C. plumosa 'Prince of Wales Feathers'. Seeds may be sold as mixtures.
