Geyer willow occurs from southern British Columbia southward in the mountains to central California, central Arizona, and southern Colorado. It is widespread in the Cascades, Sierra Nevada, and northern and central Rocky Mountains, and is found in scattered mountain ranges in southern Idaho, eastern Oregon, Nevada, northern Utah, southern Colorado, and Arizona.
This plant is present in at least 12 states/provinces in this country.
Geyer willow is larger than many associated shrub willows. It grows as a large deciduous shrub or small tree sometimes up to 20 feet (6 m) tall. It is usually found in somewhat open stands, occurring as well-spaced individuals with numerous, straight, nearly erect stems arising from a tight basal cluster. Male and female flowers occur on separate plants in erect catkins. The fruit is a two-valved capsule.
Geyer willow begins to bloom as early as May, to as late as the end of August.
