Celosia, commonly called feather celosia, feathered amaranth or botanically known as Celosia argentea (Plumosa Group). This well-known plant is mainly used as an annual except in zones 10 and 11, where it can be grown as a perennial. Celosia is easily grown in moist, well drained soils in full sun, but can tolerate some light shade and dry soils. Deadheading spent flowers will prolong bloom times. This old garden favorite features narrow-pyramidal, plume-like flower heads that are on display throughout summer and into the fall. Celosia comes in a variety of colors, such as bright shades of orange, red, purple, yellow and cream.
Celosia has no serious insect or disease problems but is susceptible to rootrot in poorly drained soils. Use these plants in mass, in beds, cutting beds, borders and in containers. Other varieties that are closely related to Celosia argentea are Celosia caracas, Celosia cristata, and Celosia spicata.
