This is an older Peony that was here when we bought the house over 10 years ago. It has light pink outer petals with a yellowish white interior. Foliage is green.
Primevere? Just a guess--a friend of mine has one that looks similar to this that she says is primevere. This from Buck Canyon Gardens: Peony Primevere is a anemone form peony, creamy white guard petals that may open with light pink coloring, and a canary yellow center that fades to cream.
