Royal Roja Oca Tubers – Oxalis Tuberosum
Oca is a traditional food native to the Andes region of South America. These Oca were re-introduced by Dr. Alan Kapuler, PhD, public domain plant breeder, of Peace Seeds in Corvallis. Oca produce round to cylindrical tubers 1–6″ long with sprawling succulent stems. They grow similar to potatoes. Traditionally the tubers are exposed to sun and cold for several days after harvest to increase sweetness. Sun exposure also enriches the vivid colors of the Oca tubers.
