Is there a compatible flower to plant near peonies? I planted peonies on the side of my house this past fall and am hoping to plant more flowers around them. Would hydrangea be okay to grow next to peonies, and if so, how far should I space them away from the peonies? What other flowers would be good to plant with peonies?

Many plants are ideal companions for peonies, especially other perennials. Some of these may include iris, dianthus, lily varieties, aster, rose, and hollyhock. Small shrubs, like hydrangea, will also work provided that they share the same growing conditions and are not planted too close, which could lead to overcrowding issues.
