Where to start in Merrimack County
If you have only one spot to fill, sun all day is where Merrimack County gives you the most rated choice (265 plants), and Blackeyed Susan (Rudbeckia hirta) is the easiest start on that list. Under trees is the hard one here: 83 rated plants, so for that spot it is worth asking a local native-plant society about the 433 unrated natives too.
