Black Turmeric (Curcuma caesia) is a rare and exotic variety known for its dark, bluish-black rhizomes. It thrives in warm, tropical climates and prefers well-draining, loamy soil. Black Turmeric can be grown in containers, making it accessible for indoor or small-space gardening. Ensure the container is deep enough to accommodate its root system and has good drainage. This plant requires partial to full sunlight and regular watering to keep the soil moist but not waterlogged.
