Costus is a genus of herbaceous perennial plants in the family Costaceae, described by Linnaeus in 1753.[2]Template:R/superscript[3]Template:R/superscript It is widespread through tropical and subtropical regions of Asia, Africa, and the Americas.[1]Template:R/superscript[4]Template:R/superscript[5]Template:R/superscript
Costus is often characterized and distinguished from relatives such as Zingiber (true ginger) by its spiraling stems. The genus as a whole is thus often called spiral gingers, but this can also refer to C. barbatus specifically.[citation needed] It is important not to confuse Costus scaber, C. spectabilis etc. with the herb known by the common name "costus".
Costus spectabilis is the floral emblem of Nigeria; its flowers are represented (erroneously in red instead of yellow color) on its coat of arms.[6]
Costus productus and Costus guanaiensis are among the species of Costus with edible flowers.[7][8][9] Other Costus species' flowers have also been determined to be edible.[10][11]
Some Costus species have traditional medicinal and veterinary uses. For example, in Trinidad and Tobago, a mix of Costus scaber juice and crushed Renealmia alpinia berries is used to treat dogs bitten by snakes.[12]
Costus naturally hybridizes, and commercial hybrids have also been produced.[13]
