Salix rotundifolia, commonly known as Round-Leaf Willow, is a deciduous perennial shrub native to alpine and subalpine zones in Western North America, including wet meadows, stream banks, and lakeshores. It is a rapidly growing species that typically reaches a height of 6-30 feet (1.8-9 meters) and a width of 6-20 feet (1.8-6 meters). The Round-Leaf Willow has a bushy form with multiple stems and round, bluish-green leaves. Its flowers are yellow or green catkins that appear in early spring before the leaves, and while they are not particularly showy, they are important for early pollinators.

The Round-Leaf Willow is valued for its ability to stabilize soil in riparian zones and for its wildlife habitat benefits, providing food and shelter for various species. It is used in restoration projects, as well as in garden settings for naturalistic plantings. This willow thrives in full sun to part shade and prefers moist to wet soils, such as clay, loam, or sandy substrates with high water availability. It is tolerant of cold temperatures and can withstand periodic flooding. Gardeners should be aware that willows can have aggressive root systems that may interfere with underground utilities or structures.CC BY-SA 4.0
