There’s a fashion at present for re-visiting South American vegetables that were rejected in favour of the Potato back in the day. Oca is an Oxalis, the leaves are a total give-away and when they flower it’s even more obvious. The tubers are on the small side, can be eaten raw or cooked up like tiny potatoes, the ones you would normally throw away. One of the top qualities of Oca is the variety of tuber colours, they range from yellow through gold to orange, pink and red. In my cold clay garden Oca does not perform well, a lot of work for a few tiddley tubers but in a sunny garden on good soil, who knows, they might be worth some space. Folks who want to avoid eating Solanaceous plants will find Oca a good alternative to potatoes.
