Recommend another with fragrance!
I have 3 peonies that I purchased for the fragrance first, and their shrubby form in the garden second. Festiva Maxima is nice, but not the overwhelming fruity-sweet old-peony scent I grew up with, and its foliage is a little coarser than I really like. Sara Bernhardt was recommended as a pink, but unless it's mismarked, I get very little from it in terms of fragrance.
Divisions of my parent's still-unnamed pink peony is the only one that yields overwhelming perfume every spring. I'm ditching SB and replacing it. I don't mind peony rings, because I'm after fragrance, which seems to come with big, floppy blooms.
