This large native tree is found across a wide geographic range from western Florida to southern Minnesota. Best growth is achieved in moist, alluvial soils but Black Walnut is found in a wide range of soil types both acid and alkaline, and wet and dry. There are some plants (especially tomatoes) that are known to be incompatible with the root system of Juglans. Other plants, bluegrass for example, do just fine. The delicious nuts are a favorite of wildlife and hungry humans.
