The English walnut, scientifically known as Juglans regia, is a species of walnut native to the regions of Central Asia and Southeast Europe. It is widely cultivated for its edible nuts, which are rich in healthy fats, protein, and essential nutrients. The tree can grow up to 100 feet tall and produces a round, green husk that encases the hard shell of the nut. English walnuts are commonly used in cooking and baking, adding flavor and texture to various dishes. They are also popular for their wood, which is valued in furniture making and cabinetry. The nuts are typically harvested in the fall when they ripen and fall from the tree.
