Look up some seed selling websites to find some to buy. The guide here says to plant by Nov so you need to hurry.

Jane: You can buy oca in the USA at www.cultivariable.com. Delia: Okra, the edible pod, is Abelmoschus esculentus. Oca, a tuber, is Oxalis tuberosa. In Australia, you might be more familiar with it under the name "New Zealand Yam".
