Where to start in Siskiyou County
If you have only one spot to fill, sun all day is where Siskiyou County gives you the most rated choice (429 plants), and American alpine speedwell (Veronica wormskjoldii) is the easiest start on that list. Stays soggy is the hard one here: 173 rated plants, so for that spot it is worth asking a local native-plant society about the 1,221 unrated natives too.
