I'm fortunate to have beautiful peonies bloom in late spring and early summer; I wish they lasted longer. Within a few weeks, however, the summer blooms begin: black-eyed Susans (rudbeckia) and coneflowers. The colors are perfect in the summer heat. My early hydrangea begins turning from white to pink, too. I do love the summer perennials. Just this week, I purchased two more plants: deep red coneflower and deep red rudbeckia.
