Where to start in Umatilla County
If you have only one spot to fill, sun all day is where Umatilla County gives you the most rated choice (329 plants), and Alkali buttercup (Ranunculus cymbalaria) is the easiest start on that list. Stays soggy is the hard one here: 124 rated plants, so for that spot it is worth asking a local native-plant society about the 547 unrated natives too.
