Celosia argentea
From Wikipedia, the free encyclopedia (Redirected from Plumed cockscomb)Description
Celosia argentea (Syn. C. plumosa, C. argentea. var plumosa) is a tender annual that is often grown in gardens. It is propagated by seeds. The seeds are extremely small, up to 43,000 seeds per ounce.
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.
Cultivation
These plants are of tropical origin, they grow best in full sunlight. The flowerheads can last up to 8 weeks, and further growth can be promoted by removing dead flowers.
Varieties
Celosia cristata, also known as Flamingo Feathers is a specific annual that can grow up to 2 feet in height. The colors are predominantly pink to light violet, and the leaves are a darker green, when compared to C. argentea. May be sold as C. cristata 'Flamingo Feathers'.
Celosia plumosa, also known as Prince of Wales Feathers, [1] is a synonym for Celosia argentea. Often sold as C. plumosa 'Prince of Wales Feathers'.
Seeds may be sold as mixtures.
Taxonomic issues
Horticultural usage may be very confusing. For instance Celosia cristata may be listed as a separate species, or a variant of C. argentea. Other names for C. argentea plumosa include Celosia argenta pyrimidalis, C. argentea cristata, and C. spicata
Other classification consider there are three variants;
C. a. var. argentea
C. a. var. cristata
C. a. var. plumosa Voss
