Sounds like you're looking for drought tolerant annuals and perennials for the area beneath the eave. I'd start by removing the tainted soil and replacing it with fresh potting soil. You can blame cats for wanting to dig in the nice soft potting soil but their urine can burn the roots of plants - not to mention the odor the urine causes - so after you've planted your new plants, try laying chicken wire or hardware cloth over the soil between the plants. This will keep the cats out of the bed and eventually they'll find another place to relieve themselves. Some plants for you to consider growing in the bed include Agastache foeniculum - Anise hyssop; Amsonia; Artemisia; Asters; Baptisia australis - False blue indigo; Centauria montana - Perennial bachelor?s button; Coreopsis spp.- Coreopsis; Dianthus spp. - Pinks; Echinacea purpurea - Purple cone flower; Echinops ritro - Globe thistle; Erygium spp. - Sea holly; Euphorbia sp. - Spurge; or Gaillardia spp. - Blanket flower. Or, you might plant daylilies or irises in the bed. Hope these suggestions are helpful.
