Juglans regia, commonly known as the walnut, is a deciduous tree native to regions of Europe and Asia. It typically grows to a height of 20 to 30 meters and features broad, pinnate leaves. The tree produces a round, green fruit that encases the edible walnut seed, which is rich in healthy fats and nutrients. Walnuts are not only valued for their taste but also for their health benefits, including omega-3 fatty acids and antioxidants. The wood of Juglans regia is highly prized in furniture making and cabinetry due to its durability and attractive grain.
