I knew I would get sidetracked - I meant to comment on the Peony Shop auction. If I'm not mistaken, while they all have names, these are registered with the US Patent & Trademark Office but not necessarily with the APS, which is the international registry for peonies. In addition, if they decide - after further evaluation - that some are worth it, they will slap a European and possibly North American, Plant Royalty on those, even if owned by other people already.
I do agree many are beautiful but going by just their faces, they are like very many available already and which are considerably cheaper
I think I would have to win a very big lottery to bid over 500 euro for just a face
