I have a wedding cake coming up and the bride wants to have gerbera daisies in the cake. What's the best way to go about doing this? There will be three or four on the top of the cake, and a couple around the edges on the different layers. Her florist is going to provide them, but I have NO experience with fresh flowers. Thanks!!

First thing you want to check is to make sure that the flower is non-toxic.

Here is a list of all non-toxic flowers:

Second the best types of flowers to use are organic flowers as they are pesticide and herbicide free. Ask the bride to get organic flowers and to ensure that the florist does not cross-contaminate them.

Do not lay the flowers directly on the cake, using wax paper and then laying the flowers on top should do the trick.
