Hi Jsf, I agree with Liz's comments.
Good luck with your adventure. You will need to be careful about overwatering through the summer, as those little white roots die quickly when they are exposed to air for more than 15 minutes. Peonies are not inclined to grow those roots in warm weather. Should any of the above ground foliage start showing signs of rot ( like blackened stems) cut them off and dispose in the trash.
Most of us have dug up a peony in the spring because of a necessity, and they have survived.

Good luck! And keep us updated.
