Where to start in Napa County
If you have only one spot to fill, sun all day is where Napa County gives you the most rated choice (184 plants), and American speedwell (Veronica americana) is the easiest start on that list. Stays soggy is the hard one here: 72 rated plants, so for that spot it is worth asking a local native-plant society about the 852 unrated natives too.
