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 (345 plants), and Alkali buttercup (Ranunculus cymbalaria) is the easiest start on that list. Stays soggy is the hard one here: 113 rated plants, so for that spot it is worth asking a local native-plant society about the 1,032 unrated natives too.
