The generic name of the black walnut derives from the Latin Jovis, Jupiter, and glaus which means acorn or walnut. It is native to North America that is grown as an ornamental tree. Possibly it was introduced in Europe in the seventeenth century, although it seems that already earlier, during the 16th c., seeds or plants of this species had already gone through Sevilla, that was then a true pioneer port receiving American species in Europe.
The black walnut is valued for its medicinal qualities as well as for the quality of its wood, easy to work, being used in the manufacture of furniture, skis, and woodwork in general. A dye is extracted from different parts of the plant called nogalina, and it is used in in carpentry for dyeing wood.
