I think the forums and facebook groups are making them much more appreciated--it'd be interesting to ask some of the major growers if they're selling significantly more tree peonies over the last few years since they've been "discovered" by the casual gardener via exposure online. I know I never bought tree peonies before because I never saw them available locally, never even knew they existed 9 years ago. Bought my first one from MB, Phoenix White 8 falls ago, still wasn't that impressed. Then I saw some of the pics on the GW Peony Forum--WOW!!! Started collecting right away but that was only 4 years ago of so, most of mine will start blooming this year....Different for people who live around major growers, probably....
