About Oca
Oxalis tuberosa, commonly known as oca, is a perennial herbaceous plant cultivated for its edible tubers, which range in color from white to yellow, pink, or purple. Its trifoliate leaves and yellow flowers make it an attractive ornamental plant, especially in kitchen gardens or large pots. It originates from the Andean region of South America, where it has been a staple food for centuries.
Native range
The Andes of South America (Peru, Bolivia, Ecuador, Colombia)
Care tips
It requires full sun for good tuber production, although it tolerates some partial shade in very hot climates. Watering should be regular and moderate, keeping the substrate moist but not waterlogged, especially during tuber formation. It prefers well-drained soil, rich in organic matter, and with a slightly acidic pH. A common mistake is planting it too late in the season, as it needs a long, cool period for the tubers to bulk up properly.
