Salix scouleriana, Scouler's Willow – Woodbrook Native Plant ...A Scouler's willow (*Salix scouleriana), also called Upland Willow, is a fast-growing deciduous shrub or small tree native to western North America, known for its adaptability to drier upland areas and disturbed sites, providing crucial early nectar for pollinators and browse for wildlife, with distinctive fuzzy, rusty-colored leaf undersides.
