play4smee, Welcome
If you were to expose for the white when taking the shot, it would likely look better underexposed in the other areas. This one has almost lost petal detail. It's usually easier to bring up the yellows and greens in the center than to rescue the white.
For your post version, one thing to try is a layer over a copy of your original:
- Convert to B/W. Color balance by adding magenta, cyan, and yellow (you will find a certain amount of color exists in a white bloom. Look for a natural tint, minus the blue).
- Gently erase through this layer to bring back the other parts of your bloom.
- Contrast and darken to taste.
