Geez, I meant to include images of some more "peachy" ones from Enman Joiner.
Here's Scatterbrain:
Madge Cayse:
Peach Magnolia:
Yours possibly could be one of these Joiner cultivars? All are well distributed. I grow or have grown all of the above. Yours does seem to be lighter, so it possibly could be Scatterbrain.
Here's one with more shades of pink in it, another Joiner double : Peggy Bass. Yours sorta reminds me of this one. You can't see it so well on this picture, but both your picture and this one show ruffling on the petal edges.
