Map of distribution and habitat in USA
This plant is present in at least 13 states/provinces in this country.
Booth's willow is a native, multibranched, rounded shrub typically between 9 and 18 feet (3 and 6 m) tall. On well-drained soils in Oregon, Booth's willow is broadly rounded and has many stems, but in bogs, it is dwarfed and has few stems. At 10 years of age, Booth's willow reaches a height of approximately 8 feet (2.5 m). Stems reach senescence between the ages of 15 and 20 years. Male and female flowers occur on separate plants in 0.5- to 1.5-inch-long (1-1.5 cm), erect catkins.
Booth's willow flowers in late spring or midsummer, from May to June. The fruit ripens soon after plant flowering, followed by seed dispersal in late July and early August.
