Description
Black walnut (Juglans nigra) is a large riparian zone tree native to North America. It is cultivated for nutritious walnuts and the high-quality dark timber. Juglans nigra produces juglone, a compound that inhibits the growth of other plants in the walnut tree’s proximity, so it may be undesirable near lawns and gardens. It is susceptible to Thousand cankers disease.

General Info
Name story
Black walnut
Walnut is actually derived from "walhnutu" from the Anglo-Saxon language meaning "foreign nut", as the nut originated from Italy and Gaul. Juglans nigra is called black walnut to differentiate itself from the indigenous nut, hazelnut. Also, its tree bark is greyish-black in color and its wood is dark-colored by nature. Hence, it is called the black walnut.

Usages
Garden Use
Black walnut is a beautiful enough tree to have earned an Award of Garden Merit. It is commonly grown commercially, in large public parks or very big yards (it usually grows to around 30 m tall), as it provides excellent shade; but is too big for urban areas. Black walnut is usually planted as a standalone specimen due to the toxicity of falling fruits that can harm other plants, but trees like the sugar maple and flowering dogwood work well with it.
Care Guide for Black walnut
Water
Established Black walnut trees will need watering every three weeks during the active growing season, and less if the weather is rainy. Do not let the soil dry out completely between waterings, especially if the tree is younger or the weather is hot, as Black walnut does not tolerate dry conditions.
