Rosy Gems Oca Tubers
Rosy Gems Oca Tubers – Oxalis Tuberosum are a variety of oca made popular by the Occidental Arts and Ecology Center in Occidental, California. The color is, unsurprisingly, pink. It gets redder with exposure to light. White flesh with a red/purple center.
This variety doesn’t seem to make particularly big plants, at least in our climate, but yields better than the size of the plant might suggest. 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.
