Narrative
A plant evaluation was executed at the Natural Resources Conservation Service Plant Materials Center, Corvallis, OR testing 24 sources of Columbia River willow. 'Multnomah' was selected for overall superiority in growth rate and form. A medium to large shrub that grows to a height of 10 to 20 feet depending on the site. Multi-stemmed and compact with upright slender branches, this species is known for its spreading or suckering habit. Young twigs are brown or green and smooth to slightly hairy. The bark of older limbs becomes grayish-brown and scaly with age. 'Multnomah' is a male clone flowering in May or early June. They are upright and flower after leaf formation in spring. Primary use for streambank stabilization along low velocity flow rivers. Area of adaptation is restricted to areas west of the Cascade Mountains in Oregon and Washington below 1,500 feet elevations. Originally collected in 1980 from plants growing along the banks of the Sandy River in Multnomah County near Portland. Released by USDA-NRCS in 1988 in cooperation with the Oregon Agricultural Experiment Station and Washington Agricultural Research Center.
