Symbolizing happiness, there may be no more relevant flower for a wedding than the peony. Full of soft, fluffy petals, peonies have become the new wedding flower staple. Although they can be spendy per stem, their size helps to fill out a bouquet or centerpiece. For weddings with a really pale palette, peonies are a perfect option because of all the texture they lend to light colored arrangements. For those of you who love fragrant flowers, peonies smell delicious. But if you are a little scent-sensitive, you may want to find another bloom to use for the majority of your decor and bouquets.
