Answer: As for selecting plants, I am not sure if you just want to cover the ground or you actually need plants specifically designated as ground cover. I chose perennial flowering plants because you said this area will not be walked upon. If you do need strict ground cover without flowering feature please let me know. You can try some or all of the following for this area : Aruncus (Goatsbeard), Astilbe (Meadowsweet), Cimicfuga (Bugbane), Filipendula (Queen of the Prairie), Lobelia cardinalis (Cardinal Flower), Lysimachia (Loosestrife), Mertensia (Virginia Bluebells), Primulajaponica (Japanese Primrose), Trillium grandiflorum (Wakerobin), Trollius (Globeflower). Best wishes with your landscape.
