The only thing you need is a fast shutter-speed to freeze the motion. How fast depends on the breeze and magnification but 1/2000s or around that should be good.
Magnification is how big the flower appears in the photo. If you are filling the frame with a flower, then movements will be far more perceptible than if your flower is in the corner at one tenth of the frame.
To get the background to blur you need a wide aperture, Go the widest your lens can do which I think is F/2.8, depending on which 60mm you have. Incidentally, this will also favor a high shutter-speed.
Should you still not have enough light to get a proper exposure, raise the ISO.
