Many of these perennial plants will do well in the site you describe: Rudbeckia, Yucca, purple coneflower, Coreposis, yarrow, bee balm, Aster, butterfly weed, hyssop, Sedum, and Artemesia. This list goes on, but these are some of the low-maintenance plants. Also, a good flowering shrub to try is Rosa Rugosa.
This is a good Web site to visit for other selections of native, low-maintenance plants:
