I have a couple of peonies that do OK in some western exposure with a fair amount of shade. Have a bunch more in pots that I need to get in the ground, including a couple of tree peonies. Can anyone tell me if they will still bloom if I plant them in spots where they only get about 2 hours of sun? I only have room for about 2 more in the very sunniest place in the yard, but too many pots, too few spots....Thanks
