Where to start in Contra Costa County
If you have only one spot to fill, sun all day is where Contra Costa 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: 91 rated plants, so for that spot it is worth asking a local native-plant society about the 815 unrated natives too.
