Where to start in New Castle County
If you have only one spot to fill, sun all day is where New Castle County gives you the most rated choice (421 plants), and American speedwell (Veronica americana) is the easiest start on that list. Under trees is the hard one here: 152 rated plants, so for that spot it is worth asking a local native-plant society about the 762 unrated natives too.
