rosebudestates said: I didn't feel that the intent of the article was to call out the "10 worst" peonies. It was more that people often gravitate to the same few popular cultivars without regard to their failings. They didn't explicitly say it, but this could result in a disappointed gardener if only a handful of peonies were grown. Of course this doesn't apply to anyone on this board, anyway.
It was a bit tongue in cheek - I believe they also commented that trying to plant every cultivar from a given hybridizer, even the not very successful ones, was not wise. Given that the APS President is doing just that, I suspect a bit of leg-pulling.
