Substrate: acidic soil (mostly on siliceous substrata)

Altitudinal range: from the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus) to the subalpine belt (potential vegetation: open, taiga-like forests dominated by Larix decidua and/or Pinus cembra and Rhododendron)

Note: on mainly siliceous, often sandy mineral soil in clearings of Calluna-heathlands, with optimum in wind-exposed situations; widespread throughout the Alps.
