The Celosia plumosa red variety features tall, erect stems that can reach heights of up to 2 feet (60 cm) or more. The leaves are lance-shaped and can be either green or tinged with red, depending on the variety. The most distinctive feature of Celosia plumosa is its flower heads, which are dense and composed of countless tiny, feathery plumes. These plumes radiate outwards from a central point, giving the flower head a soft, fluffy appearance. The plumes are often deep red in color, though shades can vary from bright crimson to deep burgundy.

The intense red color of Celosia flowers makes them a standout in gardens and floral displays. They bloom profusely throughout the summer and into fall, attracting pollinators like butterflies and bees.
