Where to start in Twin Falls County
If you have only one spot to fill, sun all day is where Twin Falls County gives you the most rated choice (222 plants), and Alkali buttercup (Ranunculus cymbalaria) is the easiest start on that list. Stays soggy is the hard one here: 74 rated plants, so for that spot it is worth asking a local native-plant society about the 331 unrated natives too.
