The Black Turmeric tree, scientifically known as Curcuma caesia, is a rare and unique plant native to the tropical regions of Southeast Asia, particularly in parts of India, especially in the northeastern states. Unlike the common turmeric plant (Curcuma longa), Black Turmeric belongs to the ginger family (Zingiberaceae) and has a distinct appearance and properties. This perennial herb typically grows in the wild in forested areas and thrives in humid, well-drained, and slightly acidic soils. The Black Turmeric plant grows to a height of about 3 to 5 feet and features broad, lance-shaped leaves that are large, dark green, and glossy in appearance.
