My first guess was apricot, but google showed that that's wrong. Sorry for the somewhat tangential question. Thanks in advance.
Apple Blossom - "Malus domestica" is my best guess. There is not really enough info in the photo to distinguish between and apple "Malus" and crabapple "Crataegus". However it is more likely an apple blossom due to the color of the blossoms, the apparent arrangement of them (fasciculate or bundled; rather than corymbose or flat-shaped but starting at different points on the stem), number of stamens and their color, and my guess as to the shape and nature of the leaves in the background.
I am pretty sure that the tree is an apple :) here a picture taked from here
