Narrative
A plant evaluation was executed at the Natural Resources Conservation Service Plant Materials Center, Corvallis, OR testing 105 sources or clones comprising at least eight native willow species. 'Placer' was selected for rapid growth and high stem density at ground level. Primary use for streambank stabilization along rivers of low flow velocity. Adapted to poorly drained to well drained soils in areas of the Pacific Northwest including Washington, Oregon and northern California. Disease resistant. 'Placer' willow is a medium sized shrub that grows to a height of 8 to18 feet, depending on the site. Its form is multi-stemmed and upright to broadly branching with a rounded crown. Young twigs are yellowish-green in spring then often become tinged with red by winter. The bark of older limbs and the trunk is mostly smooth and gray. Both the foliage and twigs lack pubescence (short fine hairs). 'Placer' is a male clone where flowers emerge in mid-February to March, approximately two weeks before leaves emerge. Released by USDA-NRCS in 1988 in cooperation with the Oregon Agricultural Experiment Station and Washington Agricultural Research Center.
