Anemone nemorosa is one of my favorite species in a favorite genus! (Yes this one too ;) ) The common wild wood anemone grows almost everywhere in Norway. However, although the white form dominates, more or less pink forms exists too. Also forms with flowers in shades of blue can be found but not in Norway.
Another handsome wood dweller here is the yellow cousin Anemone ranunculoides which is less common. You can be lucky and find the progeny of the two, A. x lipsiensis where both parents grow also.
Here are some of the forms I grow in my garden (they are not collected in the wild though ;) ), pictures taken in rain! Many have cultivar names but the names have disappeared . . . .
