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 (263 plants), and Alkali buttercup (Ranunculus cymbalaria) is the easiest start on that list. Never watered is the hard one here: 75 rated plants, so for that spot it is worth asking a local native-plant society about the 420 unrated natives too.
