OCA – a very special Andean Potato


Feature Plant:  Oxalis tuberosa (OCA)

Oca is a small tuber that is a staple crop of the Inca.  They have literally thousands of types of these small potatoes…one for every micro climate in the Andean mountains.  Preserving genetic and biological diversity is essential for a changing climate.  Here is a BBC documentary on OCA  and 3000 other nutritious tubers grown in the Andes for a more resilient and nutritious food source.  https://www.youtube.com/watch?v=vSHrNwQle1E

We think that every garden should grow a patch of OCA, our favourite spud.  We have OCA available for $12 a pot.  Not too late to get into the ground for a fall crop to eat.  One plant should produce enough for one meal or leave them in the ground to expand your tuber plot for many future meals.   Makes excellent ground cover.

Suitable for: light (sandy) and medium (loamy) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils. It cannot grow in the full shade. It prefers moist soil.

Tubers – raw or cooked. An acid lemon flavour when first harvested, if left out in the sun the tubers turn sweet, so sweet in some varieties that they are said to resemble dried figs and are sold as fruits in local markets in S. America. The cooked root is delicious whether in its sweet or acid state, it can be boiled, baked etc in similar ways to potatoes. The tubers tend to be rather smaller than potatoes, with good sized specimens reaching 8cm or more in length. The slightly waxy skin makes cleaning them very easy. They contain about 70 – 80% moisture, 11 – 22% carbohydrate, 1% fat, 1% fibre and 1% ash. The carbohydrate is rich in sugar and easy to digest.

  1. Do you ship? I love Oca (or yams add we kiwis call them) and would love to plant them in my garden but I’m not on the island to come pick up. Thanks!
