Substrate: siliceous rocks,

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the alpine belt (potential vegetation: treeless Alpine grasslands and tundras, to the lower limit of perennial snow and the equilibrium line of glaciers)

Note: a mainly boreal-montane, circumpolar species found on periodically submerged siliceous rocks, sometimes also in humid forests; widespread but not common throughout the siliceous Alps.
