Where to start in Mercer County
If you have only one spot to fill, sun all day is where Mercer County gives you the most rated choice (335 plants), and American speedwell (Veronica americana) is the easiest start on that list. Under trees is the hard one here: 103 rated plants, so for that spot it is worth asking a local native-plant society about the 498 unrated natives too.
