Salix daphnoides, commonly known as the daphne willow, is a species of deciduous shrub in the family Salicaceae. It is a member of the genus Salix, which comprises the willows.
Taxonomy
- Kingdom: Plantae

The specific epithet daphnoides denotes a resemblance to the shrub Daphne in leaf shape.
Description
Salix daphnoides is a small to medium‑sized shrub, typically reaching heights of 0.5–2 m. The plant possesses slender, flexible twigs that may be slightly pubescent when young. Leaves are alternate, narrow‑lanceolate, measuring 2–5 cm in length, with entire margins and a conspicuously bright green surface that turns yellowish in autumn. The stipules are small and caducous.
The species is dioecious, bearing separate male and female catkins. Male catkins are 1–2 cm long, bearing numerous stamens, while female catkins are slightly longer and develop into capsule fruits containing numerous tiny seeds equipped with tufts of hairs for wind dispersal.
Distribution and Habitat
Salix daphnoides is native to temperate regions of Europe, with its range extending across the Alps, Carpathians, and the Dinaric Alps, as well as parts of the Balkan Peninsula. It is typically found in mountainous or sub‑alpine zones, favoring moist, well‑drained soils along riverbanks, stream margins, and wet meadows at elevations of 500–2,500 m.
Ecology
The shrub commonly colonizes newly disturbed riparian substrates, contributing to bank stabilization and providing habitat for a variety of invertebrates and small vertebrates. Its catkins are an early source of pollen for insects in spring, and the foliage is occasionally browsed by herbivorous mammals such as ungulates.
Conservation Status
The International Union for Conservation of Nature (IUCN) has not assessed Salix daphnoides separately; however, it is generally considered locally common within its suitable habitats. Threats may include habitat alteration from dam construction, watercourse regulation, and overgrazing.
Uses
Salix daphnoides has limited economic use. Historically, the flexible twigs have been employed in weaving and small‑scale basketry. Like other willows, the bark contains salicin, a precursor to aspirin, but the concentration is low and the species is not a primary source for medicinal extraction.
