Where to start in Madison County
If you have only one spot to fill, sun all day is where Madison County gives you the most rated choice (62 plants), and American speedwell (Veronica americana) is the easiest start on that list. Stays soggy is the hard one here: 19 rated plants, so for that spot it is worth asking a local native-plant society about the 87 unrated natives too.
