Ginger is a tuber which is consumed whole as a delicacy, medicine, or spice. It is the rhizome of the plant Zingiber officinale. It lends its name to its genus and family (Zingiberaceae). Other notable members of this plant family are turmeric, cardamom, and galangal. Ginger cultivation began in Asia and is now also grown in India, West Africa and the Caribbean. It is sometimes called root ginger to distinguish it from other things that share the name ginger.
