Lol! Me too! It's a stunner isn't it? I hadn't seen a two-tone one like this before and wouldn't you know, it was one of the few exhibits that wasn't labelled!
It looks quite similar to Persian Ranunculus (Ranunculus Asiaticus) but doesn't have the same close-packed petals and the pink seems darker on the one in your photograph. I hope someone can ID it for you so that I know what to buy!! :-D
