Black turmeric rhizomes ready to plant! Black turmeric has the benefits of orange turmeric but has the most amount of curcumin of any other herb. This makes it more potent. These plants are grown organically and have been planted in compost. Turmeric does need shelter from the cold, but if it dies, it should come back from the roots if well established. Harvest and replant every fall for a continuous supply of medicine for your family! The rhizomes are also a beautiful blue color!
