On occasion in my land and ranch showings in Central Texas I do run across beautiful Black Walnut trees. This Native Texas hardwood tree, juglans nigra, is sought after for its incredible wood by cabinet and furniture makers. The trees provide beauty and shade as well as delicious, protein rich, nutritious nuts for animals like squirrels and others.
The nuts are very tasty. There is a Black Walnut ice cream at HEB and many recipes for it online. I love it.
I find it interesting that Black Walnut trees are allelopathic plants, these trees can kill other plants around them. Juggling is the toxic substance in all parts of the tree and the substance the tree releases into the soil. Black Walnut is also poisonous to horses. At one time I would go to a wood mill for fresh wood shavings for my horses stalls. When they milled black walnut, I was careful to not bring any of those shavings home to my barn! Dogs can also get very sick by eating moldy black walnut nuts and shells.
