Where to start in Clark County
If you have only one spot to fill, sun all day is where Clark County gives you the most rated choice (226 plants), and Alkali buttercup (Ranunculus cymbalaria) is the easiest start on that list. Stays soggy is the hard one here: 71 rated plants, so for that spot it is worth asking a local native-plant society about the 397 unrated natives too.
