Where to start in St. Croix County
If you have only one spot to fill, sun all day is where St. Croix County gives you the most rated choice (253 plants), and American speedwell (Veronica americana) is the easiest start on that list. Under trees is the hard one here: 102 rated plants, so for that spot it is worth asking a local native-plant society about the 423 unrated natives too.
