I own this 1 ft wide, 30 ft long strip between my driveway and the neighbor's property. It's steeply angled the whole length due to my pavement being higher than the neighbor's yard. Grass turf would be difficult and awkward to trim in this location. I would prefer to plant something native and perennial that won't invade the neighbor's lawn. Ideas so far is dwarf ornamental grasses (likely not native), sun tolerant hostas (not native), maybe coneflower. Any ideas?? Midwest US Zone 5, dryish soil and sunny with some late afternoon shade.
