You have all given me an opportunity to express my opinion on some of the 'cheaper' peonies - I believe that many of those have been tissue cultured; as such they will not necessarily grow or flower the same as the cultivar that provided its cells. This is why, when I became a serious grower of peonies, I only bought from peony specialists/hybridizers. They messed up a lot of daylilies this way and we all know how so many different hosta varieties came to be - because they tissue cultured the **** out of them.
OK - that's today's grumble over
