Salix lutea, commonly known as Yellow Willow, is a deciduous shrub or small tree native to riparian zones, wetlands, and moist forest areas in North America, including central Canada and parts of the western and central United States. It can grow up to 23 feet (7 meters) tall and is often found forming colonial thickets or standing erect and tree-like. The Yellow Willow has narrow, lance-shaped leaves and produces catkins that are 1.6 to 2 inches (4 to 5 cm) long, which appear before the leaves in early spring. The catkins are yellowish and can be quite showy. This species is particularly noted for its ability to reproduce vegetatively, sprouting from stem pieces, and sexually through wind-dispersed seeds.

The Yellow Willow is valued for its use in stabilizing stream banks and for its role in revegetation projects in riparian habitats where erosion control is needed. It is also appreciated for its wildlife value, providing food and habitat for various species. In cultivation, it requires full sun to partial shade, consistent moisture, and prefers soils with slow to medium drainage. While it is not commonly used in ornamental landscaping, it serves an important ecological function in naturalized areas. Gardeners should be aware that, like many willows, Salix lutea can be susceptible to pests and diseases such as willow scab and canker. It is also important to consider its potential size and root system when planting, as it can be expansive and may interfere with structures or other plantings.CC BY-SA 4.0
