I bought a peoni that was supposed to be yellow. It did bloom yellow the first year and then it was pink after that. Can you explain how this works?

Peony flower color is determined by the pigment specific to your cultivar of peony. Healthy flowers do not change color, but pigment levels and our perceptions of their color can change. An apparent color change in your peony can be caused by many factors, the most common is that they can reseed and the new plant may revert to ancestral genes and have flowers of a different color than those of the parent plant. So, it's possible that your original peony died and a new plant grew in its place. About the only other explanation is a genetic mutation called sporting. Sporting may cause one or two of your peony flowers to bloom in a different color. Hope this sheds some light on the possibilities!
