Oca (Oxalis tuberosa) is a perennial plant native to the Andean regions of Argentina Northwest, Bolivia, Colombia, Ecuador, and Peru. Known for its edible roots, which are often compared to fingerling potatoes in taste and texture, oca thrives in light, moist conditions with full sun exposure. It prefers well-draining soil that is either sandy or medium-textured and can tolerate hardiness zones 6-9. The plant grows up to 0.5 meters tall and produces edible flowers, leaves, and roots, making it a versatile addition to gardens seeking both ornamental value and culinary interest.

Start with oca to gain experience in growing tuberous crops.
Seeds or small tubers, a sunny spot, and well-draining soil.
Plant in spring after the last frost, when temperatures are mild.
Use light, sandy soil with good drainage. Containers should be at least 30 cm deep.
Transplant small tubers about 15 cm apart in rows spaced 30-45 cm. Cover them lightly with soil.
Keep the soil moist and provide light shade if temperatures are high.
Water regularly, especially during dry spells, but avoid overwatering. Mulch to retain moisture.
Prune back foliage in late summer after flowering to encourage tuber growth and prevent bolting.
