Here are a few suggestions to get you started: daylilies (hemerocallis), purple coneflower (echinacea), yarrow (achillea), sedum, Black Eyed Susan (rudbeckia), coreopsis, Siberian Iris, veronica, perennial salvia, Japanese anemones. For more information about planning, planting and caring for perennials, you might like to take a look at a book or two. Here are some I like:
