Monet suffered with cataracts. In 1923 he had surgery to remove them from his eyes. The works he painted when he had cataracts are more red than the ones he painted after his operation. That said, I think these apple blossoms were painted by Van Gogh.
Claude Monet - Subtle contrast between red and green, and creation of green out of grays using relative colors, mid tone through drastic high and low temperature balance, canvas shape allows a lot of background with a close foreground.
