Ginger is an herbaceous perennial herb native to tropical Asia, though not found growing in the wild, and now cultivated in Latin America and Africa; it grows to a height of 1-1.5 metres. The alternate leaves are long, lanceolate in shape and dark glossy green in colour with a centre midrib and 10-20cm in length. The flowers are produced on green coloured bracts which often appear before the leaves, the flowers are yellowy-green in colour with purple lips and creamy blotches. Ginger is grown primarily for its aromatic rhizomes which are harvested and used in a variety of ways.
