mrswick, I've come across the same problem with tree peonies becoming leggy. What I would suggest is cut 1 or 2 (depending how many there are in the first place) of the main stems back to about 15cm. Do this in early spring then continue to do it each year until you have achieved the shape you want. They tend to respond well to pruning and you will definitely get regrowth from the base. By only doing 1 or 2 stems at a time you won't loose all the flower or shock the plant. Be brave and good luck. www.alisonpike.com/blog/
