Where to start in Plymouth County
If you have only one spot to fill, sun all day is where Plymouth County gives you the most rated choice (97 plants), and American vetch (Vicia americana) is the easiest start on that list. Stays soggy is the hard one here: 39 rated plants, so for that spot it is worth asking a local native-plant society about the 128 unrated natives too.
