Peonies aren't the only solution.
I'm as shocked as you are to hear me say those words. As much as I love me a giant bouquet of peonies, they're only in season for about a month here in Vancouver. So unless you're planning on shipping your flowers in from Sweden you're going to need something else. Our solution: english roses. They're floppy, full, and fantastic!
Being a wedding photographer I get the privilege of photographing a lot of wedding bouquets and Camille's bouquet is to die for. Complete with succulents, cotton, eucalyptus leaves, and pale pink english roses.
