Oxalis tuberosum
Oxalis tuberosa is a perennial herbaceous plant that overwinters as underground stem tuber. It was brought into cultivation in the central and southern Andes. In New Zealand, oca has become a popular table vegetable and is simply called yam or New Zealand yam (although not a true yam). Also, it is now available in a range of colors, including yellow, orange, pink, apricot, and the traditional red. Grown primarily by Quechua and Aymara farmers, oca has been a staple of rural Andean diets for centuries.Of all Andean root and tuber crops, oca is presently second only to potato in area planted within the Central Andean region. Oca is important to local food security because of its role in crop rotations and its highnutritional content.
