Where to start in O'Brien County
If you have only one spot to fill, sun all day is where O'Brien County gives you the most rated choice (95 plants), and American vetch (Vicia americana) is the easiest start on that list. Under trees is the hard one here: 45 rated plants, so for that spot it is worth asking a local native-plant society about the 143 unrated natives too.
