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 (129 plants), and Alpine bistort (Polygonum viviparum) is the easiest start on that list. Never watered is the hard one here: 46 rated plants, so for that spot it is worth asking a local native-plant society about the 292 unrated natives too.
