Eastern Black Walnut

Juglans nigra


A very large specimen of the eastern black walnut. I specifically wanted to get its distinctive fruit and leaves in the shot instead of its less recognizable features. Often overlaps with and confused for the Butternut, butternut fruit is more oblong in shape compared to the black walnut's round fruit. Black walnut is prized for its wood as lumber, being one of the most durable hardwoods. It's nut is also eaten and is high in unsaturated fats and protein. Black walnuts also feature endomychorrizal relationships with fungi of the Gomus genus. Black walnuts are however not without their downsides. They are allelopathic, which means they exude chemicals from their roots that are harmful to the growth of other flora to its own benefit. The plant equivalent of the dick move, if you will.


Found native through the Midwest and South Central US. Introduced in Europe and Hawaii.
