Looks more like a Hellebore to me (where's @Rense Haveman when you need him! ). Either way I love the soft glow of the flowers. Very effective.

I don't want to think about that, if you don't mind....Until Pete gives you a rub
Thanks, Rense. It is the same common name in England. In Scotland though it seems they try to smoke them!
