Flowers can be used to add really beautiful finishing touches to just about any cake. It’s important, however, to make sure flowers are attached properly, and that the right sort of flowers are used. Some plants have been treated with heavy sprays or can be poisonous, so it’s important to talk to a trusted florist about what’s safe to use and what’s not. I usually get my flowers for a Brunswick-based florist called Babylon Flowers, and they are always extremely helpful when it comes to recommendations.
The main reason you wire your flowers, apart from using the wire to hold the flowers in place, is to create a barrier between the cake and the stem of the flower. This means that the flower stems (which are often filled with sap) don’t actually come into with any of the cake.
The best time to insert your flowers is right before the cake goes on display, so that nothing wilts. It’s usually the last job I do before I take a cake to a wedding or a party.
