Where to start in Owyhee County
If you have only one spot to fill, sun all day is where Owyhee County gives you the most rated choice (326 plants), and Alkali buttercup (Ranunculus cymbalaria) is the easiest start on that list. Stays soggy is the hard one here: 135 rated plants, so for that spot it is worth asking a local native-plant society about the 630 unrated natives too.
