Distribution & location
Salix hastata grows in arctic and sub-arctic Europe , in North America and in the mountains of central and southern Europe . The deposits in southern Harz are extinct.
The spit willow thrives on fresh or moist, nutrient-rich and base-rich, humus-rich stone or clay soils in a sunny location. It grows in the subalpine and alpine tall shrubbery of the knee wood belt. It occurs together with Salix waldsteiniana in societies of the Salicion waldsteinianae association and also likes to be in contact with the Alnetum viridis. In the Allgäu Alps in Bavaria, it rises to the east above the Waltenberger House up to 2150 meters above sea level.
