I love these delicate little roses, too -- such a short bloom time, but pretty while they last.
You might want to try getting in even closer (and using macro mode) -- and there are a couple of things that help get a sharper image in this type of lighting, Living2Love777. By using fill flash or a reflector (as simple as aluminum foil over cardboard), you can get more light into the area. Or with some exposure compensation, you can get a faster shutter speed that helps avoid blur.
