Where to start in Jefferson County
If you have only one spot to fill, sun all day is where Jefferson County gives you the most rated choice (75 plants), and American vetch (Vicia americana) is the easiest start on that list. Stays soggy is the hard one here: 21 rated plants, so for that spot it is worth asking a local native-plant society about the 87 unrated natives too.
