Arthur Gayle is a possibility but I can only find the one photo, this site has a lot named alphabetically.

The description fits but I would like to see a better photo to be sure! The photo seems to show some white on the middle petals.

I picked out Grand Marshall as it is a "Medium to large to peony and anemone" but I don't think it quite fits. Yours is more of a semi-double to anemone form I think! I found a good site though!
