what is biological source of ginger

The biological source of ginger is the dried rhizomes of the Zingiber officinale Roscoe plant, which belongs to the family Zingiberaceae. Ginger is a herbaceous perennial plant that grows annual pseudostems about one meter tall, bearing narrow leaf blades. The inflorescences bear flowers having pale yellow petals with purple edges, and arise directly from the rhizome on separate shoots. Ginger originated in Maritime Southeast Asia and was likely domesticated first by the Austronesian peoples. It was transported with them throughout the Indo-Pacific during the Austronesian expansion, reaching as far as Hawaii.
