Then the drying process! Peonies can be air dry or by using a dessicant like silica gel. Air drying is easy. However, the volume of the flower will decrease. First, you need to remove leaves at the base of the stem. Then, dry the flowers by suspending them, head below in a warm and dark place. Another way to do it is by using a dessicant like silica gel for a spectacular effect! This process allows the flower to keep its size and natural shape but it is more expensive and time and space demanding.
