Answer
Black Walnut Tolerant Plants
The black walnut contains the toxin juglone, which can cause stunting, death, or wilting in many plants. The toxin can affect plants 50-60 feet around the tree but cases have been seen where injured plants were as far as 80 feet away. The following are plants that may grow in these black walnut toxin areas or are more tolerant of the toxin.
