How about taking pictures on overcast day?
If you have little dark day ,that is ok for you to click a photograph of a flower ,You have no shadows and no harsh bright spots and that makes your shot a perfect one with a good exposure.
Backlight on flowers can be another perfect click
So when the sun is directly i front of you and make your flower to glow if lighting from behind.
Wind kills your photography skills
So watchout for wind ,for that the perfect time is morning .if still there is a wind then you can use a reflector to block the wind.
Get closer
Close photographs of flowers are loved by all ,try to maintain a proper distance according to your camera lens.
use a reflector
If your flower is in shade ,try to use a reflector to focus more light on your flower .
