I see fresh flowers on cakes all the time I have always wanted to put fresh flowers on a cake. Is there a way to do it? Do I have to worry about pesticides or other chemicals? When I went to buy blue roses for a wedding cake the florist told me not to put them on the cake because of the dye and pesticides so I had to hunt for silk flowers.

I think this thread may help you out:
