Why not try to root it? You probably would have better results if you give the cutting some protection from the hot sun for a while ( in a pot), and then you could transplant it when the roots have formed. Many of us do stem cuttings in the spring. You should also get more tubers in the fall.

Awesome! I'll keep my fingers crossed that it grows roots. I cut off the top of the stem that was wilted. Hopefully this will give it a better chance.

Thanks,
