Who says fondant gets to have all the fun?

If you're head over heels for your wedding bouquet, spread the love around and consider incorporating some of those fresh blooms onto your wedding cake. It's a small way to make a big impact when it comes to reinforcing your wedding theme.

“I always tell couples I think fresh flowers take the wedding cake to the next level,” says Sue Baisden, owner of Capital City Cakes.

Fresh flowers have been a popular choice for couples for decades, Baisden says, and now—thanks to Pinterest—she sees the flowers added onto cakes in unique and striking ways.

But when adding fresh flowers to a cake, there are a few things couples should consider. The type of flower that will work best for each individual cake will depend on the dessert's structure, size and style.

Michelle DeSantis of DeSantis Florists says most couples choose flowers that match their theme, but popular picks are roses, hydrangea, ranunculus and dahlias.

Laura Kick Molter, wedding consultant at Our CupCakery, says she's seen couples request a more natural, rustic look to their flowers and cakes lately as trends veer away from over-the-top glitz and glam.

“We're doing a lot of greenery without actual florals these days,” Molter says. Baisden agrees, mentioning succulents as a frequent option when couples want something more subtle.

Changes are also being made in how couples would like the flowers arranged on the cake, DeSantis says.

“It used to be done around the base of the cake and maybe at the top,” she says. “But now they're running flowers from top to bottom and throwing clusters on different layers and adding accent pieces around the cake.”

Baisden says she's put flowers on almost every type of cake, but Kick Molter advises paying attention to the structure of your cake when considering which flowers to choose. The size of certain flowers and the structure of some cakes might make it difficult for the flower to stay on—or the bloom could simply look out of place.

“If you have a small shelf of room, like when a 6-inch cake is stacked on top of an 8-inch cake, you only have an inch of space between them,” Kick Molter says. “If your florist provides a 3-inch rose, it's going to stick out and look silly on the side of a cake.”

And as with any time you're dealing with multiple vendors on a single element of your wedding, it's important to make sure everyone understands the timeline and what's expected of them on the big day. Your venue, the baker and the florist need to coordinate to ensure proper delivery and placement of the flowers.

DeSantis says there are times she's unable to be on-site to put the flowers on a cake herself; if that occurs, she'll send a diagram so the person setting up knows exactly how it should look. She also advises putting the flowers on the cake as close to the time it will be on display as possible, because “once the flowers are out of water, they will begin to wilt.”

Couples concerned about food safety should speak to their florist, DeSantis adds. Chances are your baker won't know specific information about how food-safe certain flowers are, so consulting the florist beforehand about any allergy, toxicity or pesticide concerns is the best option for you and your guests.
