Brought a lovely yellow peony last year to go in my yellow border. This year it has opened its bud to reveal a pink flower. What has gone on to change the colour. Soil type is clay. Any information will be appreciated.
The plant flowered yellow last year. That's what I can't understand why pink this year.
Having problems too. I purchased a Sarah Bernhardt and a Duchesse de Nemours, both seem to be pink. This is the first year so I am presuming I have been given the wrong plant.
not what I expected but still nice
If they are tree peonies, most of those are grafted. If the grafted plant dies, the rootstock may grow and flower which would explain the different colour. While normal (ie herbaceous) peonies should be planted shallowly, that is not the case for tree peonies which should be planted about 4 inches deeper than the pot they came in (or soil mark on the stem if they were bare-root plants.) Doing this will prevent the grafted plant on top being killed by a hard frost and also allow the grafted plant to put down its own roots.
If they were hebaceous peonies, I have no idea how they could possibly change colour!
