Where to start in Winnebago County
If you have only one spot to fill, sun all day is where Winnebago County gives you the most rated choice (364 plants), and American vetch (Vicia americana) is the easiest start on that list. Under trees is the hard one here: 128 rated plants, so for that spot it is worth asking a local native-plant society about the 683 unrated natives too.
