Occurrence

In the Eastern Alps the snow sorrel occurs rarely, but mostly in smaller, individual- rich stocks; in the German Alps it is found only in the Allgäu Alps; in Austria, east in the Northern Limestone Alps and the Dachstein in the Austrian Central Alps it occurs very rarely, indeed by the Silvretta eastward, in the Western Alps to the Bernese Oberland and the Upper Valais.

The snow - dock populated Schneetälchen and moraines, especially at altitudes between about 1500 to 2500 meters in the Alps. He needs lime and rich, moist and long snow-covered soils in alpine climate.
