A male cultivar of S. alba with a nice straight to slightly bent trunk and a narrow oval to ovoid crown. Height to approx. 25 m. Often used in landscaping as a pollard willow and then remains significantly lower. The yellowish brown to grey trunk has grooves and is somewhat corky. Young twigs are yellowish brown and very bendable: they are often used for wickerwork and basketwork. The lanceolate leaves are dark green and slightly shiny on top. The leaves are bluish green on the underside. Both sides are slightly hairy with silvery hairs. The yellow catkins appear at the same time as the leaves. Roots grow close to the surface, with very many root-hairs. It grows in moist places and can stand temporary submersion, but also thrives in dryer places. Of the cultivars of S. alba, 'Belders' is the most resistant to watermark disease.
