'Kopper Kettle' peony blooms work as well in a vase as they do in the garden. This Itoh hybrid peony requires no staking to keep the flowers upright. It grows 2.5 feet tall and 3.5 feet wide and is hardy in zones 4-8. More sun means more flowers, but afternoon shade keeps the blooms from fading as quickly.
In this arrangement I also used coppery-pink buds from Filipendula hexapetala, cream buds from 'June Bride' heuchera, and chartreuse buds from lady's mantle (Alchimella mollis).
White hellebore (Lenten rose) blooms that had aged to green added texture along with green buds from 'Blueberry Muffin' viburnum.
The young shoots from my 'Scarlet Pearl' snowberry bush (Symphoricarpos) had a coppery cast that echoed the color of the peonies.
What fun it is to create an arrangment with garden flowers that are a little different from what one usually sees in floral arrangements.
