@SoCalGardenNut I am talking about the distance between peonies in the rows and individual peony plants, not under planting or mix with different species - I can perfectly grow tulips, penstemons, lupins, sedums, etc in the space between and prefer to do so. It gives longer season of interest and better combinations of color. But I can understand people who have space, growing for cut flowers or simply prefer mono-culture. Unfortunately I do not have space to make separate garden rooms.
@krazyquilter And I certainly will never plant peony so close to the hedge as at one of MS pictures - see above link. For me and probably everyone on this forum it simply does not make sense. Those peonies are going to struggle and certainly better to be moved to another better suited place. They may give flowers, but nowhere on the scale of free-standing and well-spaced plants.
Last year my Red Charm had around 15-18 blooms. You squeeze it closer with another one and get may be 5? Perhaps if you want diversity it make sense.
