Ginger (Zingiber officinale) is the underground stem (rhizome) of a tropical flowering plant native to Southeast Asia. The fleshy beige coloured root is what's used medicinally, fresh, dried, candied, or powdered. The leaves and flowers aren't typically used.

Major commercial growing regions: India, China, Nigeria, Indonesia, and Nepal. India is the largest producer. Quality varies by region and growing conditions; freshness matters more than origin for everyday tea use.
