The latin name for Black Walnut is Juglans Nigra. Juglans in Latin means poison. And Nigra means black.

Black Walnut is very resistant to mold and bugs. It actually secretes poison into the ground around it. That is why you never see a black walnut tree around a garden. If you remember the old farms you would always see Black Walnut along fence lines. Or actually used as living posts for a fence. This is because Black Walnut will keep the undergrowth down all around it. So the farmers did not have to work as hard to clear the fence line.

Then some idiot had the idea of importing Multi-Flora Rose into this country. And we all know how that turned out. Tom.
