Juglans regia, commonly known as the walnut, is a deciduous tree native to the regions of Central Asia and Southeastern Europe. 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, proteins, and antioxidants. Walnuts are not only valued for their nutritional benefits but also for their wood, which is used in furniture and cabinetry due to its durability and attractive grain. The tree thrives in well-drained soil and requires full sunlight for optimal growth.
