About

Celosia argentea var. cristata (formerly Celosia cristata), known as cockscomb, is the cristate or crested variety of the species Celosia argentea. It is likely native to India, where it was saved from extinction through cultivation because of its religious significance. Indian, Burmese, and Chinese gardeners have traditionally planted it near temples. The name cockscomb comes from the flower's appearance, which resembles the crest (comb) on a rooster (cock). The plants are resistant to most plant diseases, and can thrive both indoors and outdoors. However, they do best in sunny, well-drained locations, as the plant is susceptible to fungal diseases.

Primarily cultivated as an ornamental plant, cockscomb is valued for its distinctive wavy, velvety inflorescence. The plant is often displayed indoors as decoration, and the flowers can be cut and dried for use in dry bouquets.

How to grow it

Cockscomb is easily cultivated from seeds. Despite its tropical origins, it can also be successfully grown during warmer months in colder climates. As an annual plant, it completes its life cycle in three to four months. A soil temperature of 60 °F (16 °C) is optimal for growth. Cockscomb prefers well-draining soils rich in organic matter and full sun or partial shade. Seeds can be sown indoors in early to mid-spring, with seedlings transplanted outdoors in early summer. Regular, generous watering is during the warm months is essential, and the plants will continue blooming until frost.

Cockscomb is relatively easy to grow and care for. The plant has few insect pests, though some mites are occasionally known to feed on it. The plants are susceptible to leaf spot and root rot, which can be managed with proper watering practices. Wetting the leaf and flowers should be avoided to prevent fungal diseases.

Where it grows

The octoploid form of Celosia argentea var. cristana is found worldwide in tropics and subtropics. The tetraploid form occurs only in central and southern India. Information about the cultivated cristata and plumosa varieties come primarily from cultural records from India, Burma and China, where they have been traditionally planted near religious sites and gardens. These cultivated varieties do not appear to occur naturally in the wild, likely because the plants produce relatively few seeds. The provenance of these cultivated forms is unclear, despite several investigations.

Uses

Similar to amaranth, the cockscomb can be used as a vegetable. It is most widely consumed in southern Nigeria, Benin, Congo and Indonesia. The plants are typically grown in home gardens and small farms, both for household and commercial use. Young stems and flowers are also edible. Additionally, the seeds are edible and classified as pseudocereals. Due to its resistance to pests and disease and its high crop yield, cockscomb appears to be a good alternative to amaranth.
