Hi Jody, I'm growing it in zone 4b. I just start it early indoors and then plant it outside. I will probably have a piece or two for you to start with. [email protected]

Hi Annette, Ate you still growing the Yacon? I live in the north Florida area, Glen St Mary in Baker county. Are you anywhere near me that I could see how you're growing the Yacon, or that I might have a sprout or two? I may have something to trade if you like. Tim
