Oca is an ancient tuber from the Andes. It’s in the wood sorrel family. They are easy to grow, need no attention and very little space. Oca are healthy and tasty, a valuable source for vitamin C, B6, A, potassium and iron. It was first introduced to Europe in the 1830’s to compete with the potato, it never became popular and the potato ended up on almost every Europeans dinner plate for nearly 200 years. Oca is quite rare nowadays, perhaps it’s not suitable for commercial production, however it is a good vegetable for the domestic garden. Lets make it popular again! It can be cooked in much the same ways as potatoes, our favorite way is to roast them in the oven with some oil, salt and pepper. Please note the colour of Oca tubers usually becomes more intense over the winter.

There are many other rare tubers such as Yacon, Mashua, Chinese artichoke, Jerusalem artichoke, Ulluco and Apios. Most of them quite similar to the well known potato but often healthier and can be grown with near zero maintenance. In our experience tubers can be stored in a well drained and mulched garden bed nearly all winter, or in some almost dry potting compost (or peat) in a cold well ventilated place for example in a shed. Best suits are open trays, buckets, pots or paper bags.
We like to get them off to a good start by planting them in small pots or trays in the greenhouse around March or April and plant them out into our mulched garden beds as strong seedlings in May when there is no more hard frosts. We have some videos on planting and harvesting Ocas.
