Your aperture was 32? or was it 3.2?

A smaller aperture (5.6 or smaller) would give more dof which may or may not be desirable.
I'm thinking in this case more dof is desirable as the stamens are so much closer than the leaves.
Also think about what focus metering you are using. When I shoot flower(not often anymore) I often use spot focus so I can determine which point of the flower I want sharpest and let the dof take care of the rest.
You're doing the right things and it just takes experimenting.
Keep shooting!
