I love the peonies in my garden! I have quite a few different colors and they bloom bigger and bigger every year. I put small tomato cages around most of the peony plants to support the heavy blooms. My mother always said- it never fails, once the peonies bloom it rains really hard and they droop down to the ground. For some of the larger peony plants, I placed round metal posts around the plant into the ground and I tied them up with natural twine. Of course, I picked some blooms to enjoy in the house. They smell amazing!
I have some simple jars from IKEA that I used for displaying peony blooms. A few blooms in low vases would be a perfect addition to your backyard dinner party.
