Oca is normally propagated vegetatively, by replanting tubers, which are clones. Probably because oca has been grown this way for hundreds or thousands of years, it is very difficult to get true, botanical seed, which is the key to breeding new varieties.
When you grow out true oca seed, you will get a brand new variety that you can maintain indefinitely by replanting the tubers. Plants that are propagated vegetatively are very appealing this way: if you get a plant that you like, you have a stable new variety that is all your own. Of course, we can’t guarantee what you will get. Oca is an experimental crop in North America. You may get several excellent new varieties, or you may get weak and inferior varieties, or you may get nothing at all.
Three different mixes are available:
Group 1 contains seed from only high yielding heirloom varieties.
Group 2 contains seed from all heirloom varieties plus varieties that we maintain as breeding lines but do not sell.
Group 3 contains seed from our original varieties and varieties derived from them. These seeds are OSSI open source, so if you decide to sell a variety grown from them, you must offer it under the OSSI pledge as well.
These seeds were collected from plants in Group 2, which includes our breeding lines and newly introduced varieties. Results from these seeds may be less consistent than Group 1, but the population from which they are collected is more diverse.
