Vegetative characteristics

The ear willow is a deciduous, multi-stemmed, richly branched shrub , rarely a small tree and reaches heights of 2 to 3 meters. The gray-brown bark of the twigs is initially tomentose and remains smooth, later changing its color from brown to blackish. The winter buds are brown to red, glabrous, egg-shaped and 3 to 5 mm long. The winter branches are missing a terminal bud.

The alternate leaves arranged on the branches are divided into a petiole and a leaf blade. The petiole is 4 to 10 millimeters long. The simple leaf blade is obovate with a length of up to 5 centimeters and a width of about 2.5 centimeters. The upper side of the leaf is dark green, the underside whitish to blue-green and hairy on both sides. The tip of the spade is usually twisted and the leaf margin is roughly serrated irregularly. The permanent stipules are kidney-shaped.

Generative characteristics

The flowering period extends from March to May. The ear willow is dioeciously separated sex ( diocesan ). The inconspicuous flowers appear in kitten-shaped inflorescences before the leaves shoot . The male kittens are up to 2.5 inches long and the female up to 3 inches long.

The many-seeded capsule fruit is 7 to 8 millimeters long. The fruit ripens in May and June.

The number of chromosomes is 2n = 38 or 76.


The natural range of the ear willow extends over Europe and western Asia . In Central Europe , the ear willow thrives from the lowlands at altitudes of up to 1800 meters in the northern Alps . In the Allgäu Alps, it rises in Bavaria on the Söllereck to an altitude of up to 1650 meters.

Salix aurita thrives best on moist, low- alkali and low-nutrient salt sand to sand loam soils . It is often to be found in flat moors , spring swamps and at the edges of ditches. The ear willow, which needs light, often grows outdoors , but is also associated with Sal willow ( Salix caprea ), downy birch ( Betula pubescens ), gray alder ( Alnus incana ), black alder ( Alnus glutinosa ) and buckthorn ( Frangula alnus ). It is a characteristic species of Salicetum auritae from the Association Salicion cinereae and also comes in plant communities of the sub-association Frangulo Rubenion ago.
