Salix purpurea, commonly known as purple willow, is a deciduous shrub native to Europe and parts of Asia. It typically grows in wetland areas and can reach heights of 3 to 6 meters. The plant is characterized by its slender, flexible branches and narrow, lance-shaped leaves that turn a vibrant yellow in the fall. This species is often used in landscaping and erosion control due to its ability to thrive in moist soils. Additionally, Salix purpurea is known for its medicinal properties, as it contains salicin, a compound similar to aspirin, which has anti-inflammatory effects.
