Where to start in San Juan County
If you have only one spot to fill, sun all day is where San Juan County gives you the most rated choice (349 plants), and Alkali buttercup (Ranunculus cymbalaria) is the easiest start on that list. Stays soggy is the hard one here: 123 rated plants, so for that spot it is worth asking a local native-plant society about the 980 unrated natives too.
