Where to start in Warren County
If you have only one spot to fill, sun all day is where Warren County gives you the most rated choice (350 plants), and American speedwell (Veronica americana) is the easiest start on that list. Under trees is the hard one here: 101 rated plants, so for that spot it is worth asking a local native-plant society about the 533 unrated natives too.
