White peony

I had to go into Edinburgh this morning so a late afternoon blip from the garden. I'm not sure how old this peony is. It was in the garden when I came here 30 years ago. I had to move it a few years ago as it wasn't getting enough light. Since then it's not done too badly but for some reason this year it has only one bloom - a beauty too. I think the heavy snow in February may have affected it. Hopefully, there will be more flowers next year.
