jvdubb, in your first picture where the root was exposed it looked to me that there was some tree peony root growth with the remaining herbaceous nurse root still attached. If the herbaceous root is still viable it can start growing a herbaceous peony; not a good thing for the newly forming tree peony root. You'll want to plant a tree peony much deeper than a herbaceous to keep that from happening. If you have any new growth from the ground and the leaves look different from the tree peony leaves pinch them off as low as you can get, right down to include the eye if possible.
