Turmeric is a perennial herb widely cultivated in Southeast Asia for its rhizomes, which are used to make a curry spice, create a yellow dye, or utilized for medicinal purposes. 

Here is a summary of the characteristics of a turmeric plant:

The turmeric plant was first discovered in Southwest India more than 2,000 years ago. Besides India, turmeric has been naturalized in Asian countries like the Philippines, Indonesia, Malaysia, Cambodia, China, and Thailand. 

You can easily grow it by placing a small piece of the plant’s root in the soil, and it will germinate on its own. 

The turmeric rhizomes can be harvested 6 to 9 months after planting, usually during fall. They are thick and branched and can be boiled, dried, ground, or peeled to produce curry powder or used for medicinal purposes. 

Turmeric contains an active chemical called “curcumin,” which causes its bright yellow extract, commonly used as a dye or food coloring agent. This chemical is also an antioxidant, anti-inflammatory, anti-microbial, and immune-boosting agent.
