Though beautiful in their own right, Chrysanthemums and ornamental Kale need not be the extent of your end-of-the-season garden display. There are surprising numbers of beautiful flowering perennials that are at their best in late summer and fall, including Black-Eyed Susans, Purple Coneflowers, Boltonia, and Asters. But the most important secret of a breathtaking, late-season garden is the use of Ornamental Grasses, especially the warm-season varieties that begin to send up dramatic plumed seed heads around Labor Day. These usually begin as silky tassels, then expand into fluffy flags that last well into winter. After freezing temperatures turn the perennials brown, leave most of them standing along with the golden Grasses. They will provide a striking winter display, especially when blanketed by snow. This design works well as either a free-standing border or as an element modified to fit into an existing garden. If you can, position this garden so that either the rising or setting sun illuminates the arching leaves and plumes of the Ornamental Grasses.
