On Friday my firstborn and I hiked to the summit of Max Patch, on the NC/TN state line and on the Appalachian Trail. The mountaintop was covered in two noteworthy types of plants: wild blackberry canes and “devil’s tomato,” also known as Carolina horsenettle. While these “tomatoes” are indeed members of genus Solanum (just like table tomatoes), you don’t want to eat them; they are highly toxic. These also plague my backyard.
