White with green leaves can be so many things in the spring woods. The common Rue Anemone and False Rue Anemone can be differentiated by the deeply lobed leaves of the false rue anemone. My inclination is to get tight with wildflowers but to get an ID the leaves need to be in the image. Even then it can be difficult to get the right species.
Technical: Multiple apertures were shot to get the best background blur and still maintain sharp flowers. Manual focus on the stem of the smaller flower was used to divide the range of focus.
