Willow trees are deciduous trees known for their long, slender branches and graceful appearance. They typically thrive near water sources, such as rivers and ponds, and can grow up to 30 feet tall. The leaves are narrow and lance-shaped, turning a vibrant yellow in the fall. There are several species of willow trees, including the weeping willow, which is famous for its drooping branches. These trees are often used in landscaping for their aesthetic appeal and ability to provide shade. Additionally, willow wood is valued for its flexibility and is used in various crafts and furniture.
