Our 140 year old Black Walnut Tree

The Black Walnut is a large deciduous tree attaining heights of 30-–40 metres (100–-130 feet). Under forest competition it develops a tall, clear bole (that part of the trunk of a tree beneath the point where branching commences); the open-grown form has a short bole and broad crown. The bark is grey-black and deeply furrowed.
The Black Walnut produces a substance that is toxic or "allelopathic" to other plants called juglone. It interferes with the healthy development of other plants, especially plants in the Nightshade family (e.g. tomatoes), causing wilting and yellowing of the foliage. This has caused some to believe that nothing grows under a Black Walnut, but there are many varieties of plants that can. Fescue grass is a type of grass that is allelopathic to the Black Walnut.
The Black Walnut is highly prized for its dark-colored true heartwood. It is heavy and strong, yet easily split and worked. Walnut wood has historically been used for gunstocks, furniture, flooring, paddles,coffins, and a variety of other woodworking products. It is so valuable that so-called "Walnut Rustlers" have been known to harvest it illegally by posing as forestry officials, cutting trees during the night, and even using helicopters to take them away quickly; such overharvesting has greatly reduced its numbers and range since colonial times.
