Where to start in Gem County
If you have only one spot to fill, sun all day is where Gem County gives you the most rated choice (141 plants), and Alkali buttercup (Ranunculus cymbalaria) is the easiest start on that list. Stays soggy is the hard one here: 53 rated plants, so for that spot it is worth asking a local native-plant society about the 169 unrated natives too.
