Frequently Asked Questions

• Should OCA have a short day requirement?

  Eliminating oca’s short day requirement would result in a plant that would form tubers earlier in the year, which would have two significant effects: it would make it possible to grow oca in areas with early frosts and it would improve yields in areas with later frosts, by allowing oca tubers to continue growing for a crucial extra month or two.

• What is Oca and how do you eat it?

  In the U.S., your best bet for finding ocas is to locate a farmers market specializing in South American produce. Described has having both a sweet and tangy, nutty flavor when cooked, oca is a great vegetable to add to soups and hearty winter stews.

• What is an OCA security classification guide?

  A security classification guide is a record of original classification decisions that can be used as a source document when creating derivatively classified documents. OCAs are encouraged to publish security classification guides to facilitate a standardized and efficient classification management program. A

• Where can I find OCA in the US?

  Ocas are most common in South America and in New Zealand, where they have become so common that many locals simply call them yams (in New Zealand, they’re often served with roast lamb). In the U.S., your best bet for finding ocas is to locate a farmers market specializing in South American produce. How to eat oca

• What are Oca tubers?

  Oca tubers are the potato-like tuberous vegetables of the oca plant (oxalis tuberosa). They’re a small vegetable that comes in a variety of colours: red, yellow, orange, purple, pink and even ‘apricot’.

• Can Oxalis and tuberosa interbreed?

  There is a group of Oxalis species named the Oxalis Tuberosa Alliance that are evolutionarily close and may be able to interbreed in some cases. See Emshwiller (2002) for more information. I see a lot of pollinator interest in oca here.

• Is OCA a perennial?

  The nearest thing to growing oca as a perennial may be the “sloppy harvest” method, where only the large tubers are taken and small tubers are left behind to grow again. This certainly works for some people, but it risks the problem of unintentionally selecting for small tuber size.

• Is it possible to breed OCA varieties with fasciation in tubers?

  It might be possible to breed oca varieties that reliably exhibit fasciation in the tubers. Some varieties of oca develop fasciation much more frequently than others and if this trait could be fixed, it would generally increase tuber size, if not yield.
