Black walnut

Black walnut is a deciduous tree native to North America, scientifically known as Juglans nigra. It is highly valued for its dark, dense, and richly colored wood, which is prized in furniture making and carpentry. The tree can grow up to 100 feet tall, with a straight trunk and a broad, rounded crown. Its leaves are pinnately compound, typically comprising 15 to 23 leaflets that are finely serrated and aromatic when crushed. In autumn, the leaves turn a vibrant yellow before falling.The tree produces round, green fruits that encase a hard, corrugated shell containing the edible walnut. These nuts are rich in flavor and nutrients, making them popular in cooking and baking. However, the tree also releases a chemical called juglone, which can inhibit the growth of certain plants nearby, a phenomenon known as allelopathy.Black walnut trees thrive in well-drained, fertile soils and are often found in mixed forests and along stream banks. They are also known for their longevity, with some specimens living for over 200 years. Beyond their economic value, black walnuts play a role in wildlife habitats, providing food and shelter for various species.
