Or Helleborus, as the real name for it is. Even called the Christmas Rose or Julros in Swedish. Beautiful, looks so delicate, but is quite poisonous when "bleeding". So it's a good idea to wash your hands after handling them, and keep out of reach from children and maybe animals(if you got chewers in your household!).
I could really imagine a bridal bouquet for me with some of these flowers in it.. Especially since you can find them in this pure white, lime, purple and black color tones. Difficult to pick which color to use though..
