Costus speciosus or Cheilocostus speciosus or crape ginger is possibly the best known cultivated species of the genus Costus. This plant is native to southeast Asia, especially on the Greater Sunda Islands in Indonesia. Costus differs from the common ginger by having only one row of spirally arranged leaves.
The species reproduces by rhizome and birds disperse seeds when they feed on the fruits.
It is cultivated in India for its medicinal uses and elsewhere as an ornamental.
