Where to start in Benton County
If you have only one spot to fill, sun all day is where Benton County gives you the most rated choice (238 plants), and American bistort (Polygonum bistortoides) is the easiest start on that list. Under trees is the hard one here: 92 rated plants, so for that spot it is worth asking a local native-plant society about the 491 unrated natives too.
