Where to start in Weld County
If you have only one spot to fill, sun all day is where Weld County gives you the most rated choice (142 plants), and Alkali buttercup (Ranunculus cymbalaria) is the easiest start on that list. Stays soggy is the hard one here: 73 rated plants, so for that spot it is worth asking a local native-plant society about the 341 unrated natives too.
