Here is another Anemone. Except for its color it looks much like a Wood anemone, but it is a bit larger and flowers a bit later. The Yellow Anemone (Anemone ranunculoides) prefers woods and a moist soil.
It is not easy to find one because it is a rare species in this region.
Here is one that grows besides a small stream, the water reflects the blue sky. The image shows clearly the involucre.
