material for a rose petal

I’ve been trying to make some fairly realistic looking roses. Pretty much all that I have left is getting a better material/texture on the petals. I’ve tried several things and haven’t come up with a satisfactory solution. My main problems are getting the petals to look realistically translucent and getting the right overall light pinkish color for the petals. Right now the inside of the rose seems to be getting too dark. I would appreciate any suggestions to fix this.
