Any one know where I could get some ulluco tubers in the uk?
Getting few tubers through the informal trade frowned on by Defra. All tubers not eaten should be destroyed due to non native virus's. They even say burn the peelings and do not compost. Best stay away from them.
Never heard of it until now but it sounds like potato COVID to me!

Grew some, and Yacon about 15-20 years ago... Yacon were the better choice. Both particularly sensitive to frost.
