Where to start in Cassia County
If you have only one spot to fill, sun all day is where Cassia County gives you the most rated choice (280 plants), and Alkali buttercup (Ranunculus cymbalaria) is the easiest start on that list. Stays soggy is the hard one here: 95 rated plants, so for that spot it is worth asking a local native-plant society about the 431 unrated natives too.
