Inca Gold Yam

Oxalis tuberosa

Also known as Oca, a high-yielding yellow-fleshed yam bred specifically for New Zealand conditions. Inca Gold produces smooth, elongated tubers up to 10 cm long and 3 cm thick, with a rich, tangy-sweet flavour that intensifies after light frost.

Oca is a traditional Andean root crop cultivated for centuries in South America, where it remains a staple in highland agriculture. Introduced to New Zealand in the 19th century, it has adapted well to cooler climates and is prized for its flavour, storability, and ease of growing.

The tubers can be left in the ground after maturity in well-drained soil and benefit from light frost exposure before harvest. Well-suited to home gardens in temperate regions and an excellent addition to any food garden.

Growing Instructions

Plant tubers from late July to mid-October once the soil begins to warm. Choose a sunny position with free-draining soil. Space yams 30–35 cm apart and plant 3–5 cm deep with the growing tip facing upward. Apply a balanced fertiliser below the tubers and cover gently with soil, such as our Potato Fertiliser.

As plants grow, keep the soil consistently moist and weed-free. Mound soil around the base of plants as they develop to encourage tuber formation and protect from light exposure.

Harvest in June or July once the foliage has fully died back. For improved flavour, allow the plants to be exposed to light frosts before lifting. Cure tubers in a dry, shaded, and well-ventilated area before storage. Store in a cool, dark place until ready to use.
