I have been trying to find a source for ulluco but have come up empty. I was hoping one of you may have a source. I have never tried it and would like to give it a try this year.
I have looked for it myself, and the only suppliers I have found are in Europe.
Even there, it is not easy to find.
I have seen the plant listed as being hardy to USDA Zone 9.
It is typically grown in equatorial regions of the Andes (and only above about 7,000 feet elev.).
Good luck.
What do you have in that there bucket? It wouldn't be a tiny ad by any chance ...
