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.
