What is so sweet and sentimental about pink wedding cakes? The color pink often symbolizes tenderness and compassion, kindness and love. Adorned with peonies and pink cabbage roses, these spring wedding cakes are even more rustic and romantic with the help of ruffled cake layers and freshly picked eucalyptus leaves. Spring and summer are when these beautiful blooms are at their peak. Peonies are a medium priced flower at about five to $10 per stem.
