Large tree 15-20 m tall with a broad crown and gray bark with deep fissures. Bare branches extending at right angles, slightly drooping, very brittle at the base. Flower buds separated from escaping, lanceolate, uzkotreugolno-lanceolate or conical, with the tip of a straight or bent down to escape, with distinct lateral carinae, and 7 (9) mm long. The leaves are ovate-oblong or ovate-lanceolate with long pointed tip, margin glandular serrate with coarse and uneven teeth dark green above, below pale green or glaucous, yulye, only slightly pubescent youth and somewhat sticky. Earrings on long hairy legs with 3-5 arcuate edged leaves, cylindrical. Stamens two, half-hairy. Ovary glabrous, ovate-conical, short stem, with a rather short column. It flowers in May, fruiting in June.
Spread almost everywhere in Europe, in the Caucasus (near Akhaltsikhe) and in Asia Minor. In Russia, found in the European part (except for the strip of the Arctic), in Caucasia and in Western Siberia. In Central Russia grows throughout.
It grows on moist sites, floodplains, coast streams, around ponds, frequent or estates. Widely cultivated in rural areas and self settles by rooting branches easily break off the wind. Extensively hybridized with white willow, presumably the entire European part of the area is dominated by brittle willow hybrids. In nature, propagated by seeds, in culture — cuttings (sticks).
The bark is used in tanning, wood goes to the various crafts (arc, shafts, troughs, Kolodny hive) as fuel and building material. The leaves are small cattle feed, as well as wild animals. Used in folk medicine. Good honey plant.
