About

Celosia argentea, commonly known as the plumed cockscomb or silver cock's comb, is a herbaceous plant of tropical origin in the family Amaranthaceae from tropical Africa. The plant is known for its very bright colors. In India and China it is known as a troublesome weed.

How to grow it

A plant of tropical origin, they grow best in full sunlight and should be placed in a well-drained area. Full sunlight means they should get at least 8 hours of direct sunlight. For healthy growth plant them in the area where they get early morning sunlight and afternoon shade. In the afternoon the sunlight is mostly harsh especially in hot summer. Afternoon shade will save the plant from excessive heat. The flowerheads can last up to 8 weeks, and further growth can be promoted by removing dead flowers.

Uses

It is used in Africa to help control the growth of the parasitic Striga plant. It can also be used in soaps.
