what is a turmeric plant
Turmeric (Curcuma longa) /ËtÉrmÉrÉªk/ or /ËtjuËmÉrÉªk/ or /ËtuËmÉrÉªk/ is a rhizomatous herbaceous perennial plant of the ginger family, Zingiberaceae. It is native to southwest India, requiring temperatures between 20 and 30 Â°C (68 and 86 Â°F) and a considerable amount of annual rainfall to thrive.ost turmeric is used in the form of rhizome powder; in some regions (especially in Maharashtra, Goa, Konkan and Kanara), turmeric leaves are used to wrap and cook food. Turmeric leaves are mainly used in this way in areas where turmeric is grown locally, since the leaves used are freshly picked.
