Peonies

My mother has just had her lovely (deep pink with white centre) peony die on her and I'm trying to find a replacement. She's 98 in January , and we can't wait for a bare root plant to mature , I'd like to find one she can enjoy next summer. This means finding someone with a mature plant they are splitting up , or even someone moving house. Unlikely I know , but we live in hope!
I'm in Harlech in N Wales, but could find a way to transport from almost anywhere if there were a chance.
