Has anyone had any success with propagating tree peonies through cuttings at all? My parents have one that's about ten feet high, that my grandfather originally grew from seed around 50 years ago - they will have to move within the next 12-18 months, and I am feeling really sad that, after so long, they'll need to leave it behind.
Most advice I've found suggests buying tree peonies
or grafting onto peony stocks: but has anyone here had any success with either layering or softwood cuttings? Or any other advice?
TIA
