The following girls do in fact have bloom art and I while I do not have a browser that can acquire the images direct, I can post them from another place. I am only listing the ones I know for a fact have the bloom art (because I can see the art) on the Nutaku version of the game.

Canna


Cherry Sage


Fritillaria


German Iris


Nasturtium


I do not have the others either evolved or at all. Sorry but at at least we can knock a few out...

(Edit: You can get a better size for each of the images by opening them in a new tab)
