Zingiberis officinale
AAA
The common cooking ginger is an herbaceous perennial with upright stems and narrow medium green leaves arranged in two ranks on each stem. The plant gets about 4 ft (1.2 m) tall with leaves about 3/4 in (1.9 cm) wide and 7 (17.8 cm) long. Ginger grows from an aromatic tuberlike rhizome (underground stem) which is warty and branched. The inflorescence grows on a separate stem from the foliage stem, and forms a dense spike, to 3 in (7.6 cm) tall. The bracts are green with translucent margins and the small flowers are yellow green with purple lips and cream colored blotches. Most gingers in cultivation are sterile cultivars grown for the edible rhizome, and the flower is rarely seen. There is a cultivar of Zingiber officinale known as 'Sunti', which comes from Java and is similar to the common cooking ginger, but forms smaller rhizomes. It is used in the same way as common ginger but is said to have better medicinal qualities. Location The common cooking ginger originated in tropical Asia, but is now grown as a commercial crop for the ginger root in Latin America and Africa as well as South East Asia. Fifty percent of worldwide ginger production is in India. The best quality ginger comes from Jamaica.
