Where to start in Penobscot County
If you have only one spot to fill, sun all day is where Penobscot County gives you the most rated choice (344 plants), and Alkali buttercup (Ranunculus cymbalaria) is the easiest start on that list. Never watered is the hard one here: 110 rated plants, so for that spot it is worth asking a local native-plant society about the 556 unrated natives too.
