Where to start in Rock County
If you have only one spot to fill, sun all day is where Rock County gives you the most rated choice (329 plants), and American vetch (Vicia americana) is the easiest start on that list. Under trees is the hard one here: 123 rated plants, so for that spot it is worth asking a local native-plant society about the 613 unrated natives too.
