Turmeric (Curcuma longa) - Description
Turmeric (Curcuma longa) /ˈtɜrmərɪk/ is a rhizomatous herbaceous perennial plant of the ginger family, Zingiberaceae. It is native to tropical South Asia and needs temperatures between 20°C and 30°C (68°F and 86°F) and a considerable amount of annual rainfall to thrive. Plants are gathered annually for their rhizomes, and propagated from some of those rhizomes in the following season.
Turmeric (Curcuma longa) - Blooming
Blooms small, 3-petaled, tubular flowers, that are often overpowered by the plants' colorful bracts.
Turmeric (Curcuma longa) - Growth
Rhizomatous perennials with fleshy roots and aromatic rhizomes. Grows best in partial shade, or bright filtered light, with moderate humidity. In areas where temperatures drop below 64°F (18°C), raise Curcuma in a warm greenhouse. A warm greenhouse has a minimum temperature of 55°F (13°C). During the day, temperatures should be set to 55-64°F (13-18°C) or above, and at night, the temperature should be at 55°F (13°C). In tropical areas, Curcuma works well as a groundcover.
Turmeric (Curcuma longa) - Planting
When ripe, sow seeds at 68°F (20°C). Conduct division in spring. Division entails propagating a plant by splitting it into 2 or more parts. Each part has its own root system and more than one shoot or dormant bud.
Turmeric (Curcuma longa) - Pest
