It was too bright out when I took this, so the color looks almost neon - sorry about that! The color is a pink, but not neon fuschia like this. It's more toward red, but not dark red like the Karl Rosenfield peony. These peonies were planted by the previous owner of the house and we don't have a clue of variety they are.
This picture was taken June 10, and they'd already been blooming a few weeks; they bloomed a little later than the white ones (also trying to ID: http://davesgarden.com/showthread/47182.html ) did. They're done at this point, though. Any ideas on what variety this could be?
