Salix geyeriana, commonly known as Geyer’s Willow, is a deciduous shrub or small tree native to wetlands, stream banks, and moist open areas in the Western United States, British Columbia, and parts of the Rocky Mountains, including Wyoming. It typically grows up to 16 feet (5 meters) tall and can form dense colonial thickets through vegetative reproduction. Geyer’s Willow has a multi-stemmed growth habit with slender branches and narrow, lance-shaped leaves. The flowers are catkins, with the male catkins being yellow and showy, appearing from March to June, depending on the local climate.

Geyer’s Willow is valued for its ability to stabilize stream banks and its use in riparian restoration projects. It provides habitat and food for wildlife, including pollinators attracted to its early flowers. This species is adaptable to a range of moisture conditions but prefers consistently moist soils. It is suitable for wet areas in gardens and naturalized landscapes, and can be used for erosion control. Geyer’s Willow requires full sun to part shade and can tolerate a variety of soil drainage conditions. It is relatively low-maintenance but can be susceptible to willow beetle infestations and fungal diseases such as willow scab and black canker.CC BY-SA 4.0
