Willow trees are known for their long, slender branches and graceful, drooping leaves. They thrive near water sources, such as rivers and lakes, and are often found in wetlands. There are several species of willow, including the weeping willow, which is famous for its dramatic appearance. These trees can grow quickly and reach heights of up to 50 feet. Willows are also valued for their flexibility and strength, making them useful in crafts and basket weaving. Additionally, they play a role in preventing soil erosion along riverbanks, helping to maintain the health of their ecosystems.
