Salix bicolor, commonly known as Two-colored Willow, is a deciduous shrub or small tree native to riparian zones, moist subalpine meadows, and waterways in the mountainous regions of Europe. It typically grows to a height of up to 13 feet (4 meters). Salix bicolor is characterized by its glabrous, brown-reddish or chestnut branches and elliptical to lanceolate leaves that are green above and whitish beneath, giving the plant its two-toned appearance. The flowers, known as catkins, emerge before the leaves in early spring and are not particularly showy, but they provide an early source of pollen and nectar for insects.

The Two-colored Willow is valued for its ability to thrive in wet conditions and is often used for stabilizing stream banks and preventing soil erosion. It is also planted in water gardens and naturalized areas. This willow prefers full sun to partial shade and requires moist to wet soil conditions. It is relatively low-maintenance but can be susceptible to willow beetle and fungal diseases. Pruning is recommended to maintain its shape and promote healthy growth.CC BY-SA 4.0
