Peonies are a lovely and very classy flower. Most importantly, peonies are perfect for weddings. If you are in the midst of picking out flowers for your big day, look no further, peonies are the way to go.
I should warn you, if you are planning to use fresh peonies, it is not guaranteed they will arrive fully bloomed. They could arrive on your wedding day still in a tight bulb. Please consider the look you are going for and the amount of risk you are willing to take. The quality of silk flowers has increased dramatically over the past decades. Ordering in silk is a great way to insure that you will get your flowers exactly as you want them.
