Where to start in Randolph County
If you have only one spot to fill, sun all day is where Randolph County gives you the most rated choice (316 plants), and American water-willow (Justicia americana) is the easiest start on that list. Under trees is the hard one here: 112 rated plants, so for that spot it is worth asking a local native-plant society about the 545 unrated natives too.
