The Black Willow (Salix nigra) is a tree native to North America, commonly found near rivers and wetlands. It can grow up to 100 feet tall and has a distinctive, slender trunk with dark, furrowed bark. The leaves are long and narrow, typically measuring 3 to 6 inches in length, and turn yellow in the fall. This tree is known for its rapid growth and ability to thrive in wet conditions. The Black Willow is often used for erosion control along riverbanks and is valued for its flexible wood, which has been traditionally used in making baskets and furniture.
