English Walnut

English walnut, (Juglans regia), also called Persian walnut, valuable nut and timber tree of the family Juglandaceae, native to Iran. The English walnut is cultivated extensively for its fine-quality edible seeds, sold commercially as walnuts. The dark fine-grained wood, similar to that of black walnut (Juglans nigra), is used for furniture, paneling, and gunstocks.

English walnut

English walnut trees have long compound leaves. The round-tipped leaflets have smooth margins, and the terminal leaflet is the largest. The petal-less male and female flowers are borne in different catkins (flower clusters) on the same tree. The fruit is a drupe and is not a true nut. The edible seed is borne within a woody pit enclosed in a thick husk. The English walnut produces fine-quality “nuts” only on fertile well-drained soils of medium-heavy texture.
