Oca is a hugely important crop in South America, but not a common sight in vegetable gardens around the world. Also known as the New Zealand Yam, due to its popularity in the Oceanic country, it is a crop that can produce tubers in lots of different colors and offers a large harvest late in the growing season.
If you are looking for new and different vegetable garden ideas, then oca might be one to consider. I discovered growing oca in the kitchen garden at Soho Farmhouse in the UK, where we grew many unique and uncommon global vegetables for different restaurants. I was amazed at the bright colors of the tubers and how many were harvested off of each plant.
