Seed Specifications

  • Common Name: Oca, New Zealand yam, Andean tuber

  • Botanical Name: Oxalis tuberosa

  • Plant Type: Herbaceous perennial commonly grown as an annual for its tubers

  • Colors: Tubers may be red, pink, yellow, orange, or cream; foliage is green.

  • Height: Generally low-growing, with spreading stems; height varies with growing conditions.

  • Sunlight: Full sun to partial shade; cooler climates generally support better tuber development.

  • Soil: Loose, fertile, well-drained soil rich in organic matter.

  • Water: Regular moisture; avoid waterlogged soil.

  • Germination Time: Depends on the seed source. Oca is usually propagated from tubers rather than true seeds.

  • Sowing Depth: If viable botanical seeds are supplied, follow the supplier's sowing directions. For tubers, plant shallowly and cover with soil.

  • Spacing: Allow generous space for spreading growth and underground tuber development.

  • Growing Zones: Best suited to climates with a long, cool growing season; local suitability depends on temperature and day length.

  • Flowering/Maturity: Tuber development generally occurs as days shorten toward autumn; harvest timing varies by climate.

  • Uses: Home vegetable gardens, edible landscaping, cooking, and traditional root-vegetable dishes.

Growing Tips

  • Choose a location with sunlight and protection from extreme afternoon heat.

  • Keep the soil evenly moist while ensuring excess water drains away.

  • Give plants room to spread and develop underground tubers.

  • Protect plants from frost and harvest tubers before the ground freezes.

Seed Storage

Store any supplied botanical seeds in a cool, dry, dark place in a sealed container. Protect them from moisture and heat. Since oca is usually grown from tubers, store planting tubers in a cool, frost-free, well-ventilated location according to supplier instructions.

Unique Facts About Oca

  • Andean Heritage: Oca has been cultivated for generations in the Andes of South America.

  • Colorful Harvest: Its underground tubers can display a range of attractive colors depending on the variety.

  • Short-Day Crop: Tuber production is often triggered by shortening daylight hours, making autumn important for development.

  • Traditional Propagation: Oca is commonly propagated from tubers, which generally preserve the parent plant's characteristics more reliably than seeds.

Growing Instructions

Planting Season

Plant oca tubers in spring after the risk of severe frost has passed. In warmer regions, choose a cooler growing period and protect plants from excessive heat. Oca needs a sufficiently long season for tubers to develop.

Sowing and Planting

Oca is generally grown from small tubers rather than botanical seeds. If your product is sold as true seeds, confirm their viability and the recommended propagation method with the supplier. For tuber planting, select firm, healthy tubers and prepare a loose garden bed or deep container.

Planting Depth and Spacing

Plant tubers a few centimeters beneath the soil surface and cover them gently. Space plants generously to accommodate their spreading stems and underground tubers. Follow supplier directions for the particular planting material provided.

Sunlight and Soil

Choose a sunny position in cooler climates or a location with partial afternoon shade in warmer areas. Use fertile, loose, well-drained soil enriched with mature compost. Avoid compacted soil, which can restrict tuber development.

Watering

Water consistently to maintain even soil moisture, especially during dry weather. Avoid waterlogging, as overly wet soil can cause tubers to rot.

Germination and Transplanting

If growing from true botanical seeds, follow the supplier's instructions for germination and seedling care. When seedlings are strong enough, transplant them carefully after frost risk has passed. When growing from tubers, plant them directly in their final growing position whenever practical.

Fertilizing

Incorporate mature compost before planting. If additional nutrition is needed, use a balanced vegetable fertilizer according to the label. Avoid excessive nitrogen, which can encourage leafy growth at the expense of tuber development.

Plant Care

Allow stems to spread naturally and keep weeds under control. Mulch lightly to retain soil moisture, but avoid burying the foliage. Protect plants from frost and extreme heat whenever possible.

Flowering and Harvesting

Oca may produce small yellow flowers, although flowering varies with climate and growing conditions. Tuber formation usually increases as daylight hours shorten. Allow the plants to grow through the season, then harvest carefully after foliage begins to decline and before hard frost damages the tubers.
