Native to tropical Asia, ginger is a perennial cultivated in the tropical climates of Australia, Brazil, China, India, Jamaica, West Africa, and parts of the United States. The rhizome, which is used medicinally and as a culinary spice, is harvested at 6 to 20 months; taste and pungency increase with maturity. The plant carries a green-purple flower in terminal spikes; the flowers are similar in appearance to orchids. Historical uses for ginger include headaches and migraines, blood pressure and flow, chills, and colds.
