Where to start in Hamilton County
If you have only one spot to fill, sun all day is where Hamilton County gives you the most rated choice (28 plants), and American vetch (Vicia americana) is the easiest start on that list. Never watered is the hard one here: 13 rated plants, so for that spot it is worth asking a local native-plant society about the 21 unrated natives too.
