Zingiber officinale

Ginger is a flowering plant whose rhizome, ginger root or ginger, is used as a spice and a folk medicine.
It is a herbaceous perennial which grows annual pseudostems. These are false stems made of rolled leaves: about one meter tall with narrow leaf blades. The inflorescences come directly from the rhizome on separate shoots.
Ginger is used as a cooking spice throughout the world. The ginger plant has long been cultivated. It came from China and spread to India, Southeast Asia, West Africa, and the Caribbean.
Ginger is also a term used to describe a red-brown colour, as in ginger hair.
