I've been wanting to grow some Oca since I first read about them in "Plants for a Future" a few years ago. I think I have the perfect climate for them - we almost never get frost here so they would be able to keep growing well into fall/early winter. Problem is, the tubers are so hard to come by in the US.
I found one site that had all these wonderful varieties - they only sell to Europe...sigh
Territorial appears to have had only one variety (which was expensive), and Nichols had an assortment, but there is no indication if they will be selling again this winter. Are there any additional US sources (or places that ship to the US) out there that I'm not finding or should I just keep checking back to see if Nichols re-lists in November or December?
