My Idlewild Farm peonies order had arrived. The roots of the herbaceous peonies look decent, average size. But the gift tree peony is spectacular! It has 3 big stems and the root system is massive. This is the biggest tree peony that I ever planted since I started growing them. Mary, you are right. I definitely scored on this purchase.
This is definitely the place to buy tree peonies. I think I may get a few more next year if I can find more space to fit them.
Here is what the bonus tree peony looks like:
