Oca | Aka New Zealand Yam (Oxalis tuberosa)

OCA | Aka New Zealand Yam (OXALIS TUBEROSA)

*Rare plant & very limited stock*

1 Oca (red) plant in a 9cm pot.

Perennial Edible Tuber| 30-40cm height & spread | Full sun | Beautiful Foliage

Note from Huw: This was the first unusual perennial vegetable I grew, and have loved it ever since! Absolutely fantastic roasted! 

Oca is a joyful addition to any edible garden—its shamrock-like foliage and vibrant tubers bring charm and nutrition in equal measure. Originally from the Andes, it’s well-suited to the UK climate, especially in wetter western regions.

Harvested after the first frosts trigger tuber growth, Oca produces knobbly, jewel-toned roots with a tangy, lemony flavour—delicious roasted, fried or added raw to salads. Give it a long season, good light, and don’t rush the harvest—your patience will be rewarded. Save a few Oca tubers back to plant next year.
