Peonies never fail to command attention, and with their bright green leaves and big, splashy blooms, they are the undisputed queen of the flower bed. Enjoyment of peonies doesn't have to end at the front door. They can be cut and put in vases where they'll continue to grace the house with cheerful elegance for up to two weeks.
Cut the peonies with pruning shears during the cool of the morning or evening, and avoid cutting them on hot days. Peonies that haven't yet bloomed or that have barely begun to bloom will last the longest. Be sure to leave a long stem.
Trim at least an inch off the bottom of the stem. Make the cut at an angle, which will provide a larger cut surface to absorb water. Trim off lower leaves that will be under the water once the peonies are put in the vase, otherwise they can rot, greatly decreasing the life of the blooms.
Put the peonies in a vase filled with cool water. Place the peonies away from windy, drafty areas and keep them out of direct sunlight.
Replace the water with fresh water every two or three days. If you trim a half inch off the bottom of the stem each time you replace the water, the peonies will last longer.
