Where to start in Washington County
If you have only one spot to fill, sun all day is where Washington County gives you the most rated choice (231 plants), and American water-willow (Justicia americana) is the easiest start on that list. Under trees is the hard one here: 76 rated plants, so for that spot it is worth asking a local native-plant society about the 509 unrated natives too.
