Bebb willow occurs from Newfoundland west to Hudson Bay and across Canada to the Yukon Territory and interior Alaska. It extends south to southeastern Alaska, British Columbia, the mountains of Washington, central California, Arizona, New Mexico, and Wyoming, through western Nebraska, Montana, and south and east from North Dakota and South Dakota to the northeastern United States.
This plant is present in at least 46 states/provinces in this country.
Bebb willow is a large shrub 10 feet (3 m) tall or a small multistemmed tree with a bushy top 15 to 25 feet (4.6-7.6 m) tall. The twigs are slender and branch at wide angles, and are thin to densely hairy. Largest mature leaves are 2.6 to 6 inches (7.2 cm) long. The bark is smooth when young but becomes rough and furrowed with age. Roots of Bebb willow are shallow and dense.
In general, Bebb willow flowers from April through July or August. The fruit ripens soon after flowering, followed by seed dispersal.
