Yes tree peony! I was given one two years ago and although it hasn't flowered yet it has out grown its space already.
I have now dug it up and put it in a large pot as I didn't relise how huge and how very quickly it would get to 4ft high and 4ft wide with multiple stems. (Another gardening blunder) never too old to learn !!!!
