While Celosia prefers moist, well-drained soil, it is tolerant of a variety of shade levels and drier soil; it does well in midwestern summers, which start out cool and wet, and end hot and dry. Plant the seeds directly after the danger of frost has passed. Native to South America, celosias have been divided into two other groups beside cockscombs. Plumed celosias have thick feathery plumes that resemble the amaranths to which they are related. Wheat celosia have small spikes, usually in pink or white.
