hee hee! I found a wonderful Cafe Au Lait tuber from last winter in the same situation, no vermiculite. It just hung out all summer in a plastic bag in the dark. Since it had no eye, it never got planted.

I have read elsewhere that yes, indeed, tubers planted the second season after harvest can and will grow. Give it a try and please report back.

I have quite a few tubers left over from last spring. Some were in vermiculite, some in saran wrap, some in peat moss and some in nothing at all, but all look viable and have either eyes or sprouts and no mold or rot. I have put them in a box and will plant the ones I need more of in a section of the garden and see how they do. Can't stand to throw things away with potential! If they are varieties that I lost over the summer, I will put them on the bench and take cuttings.
