Substrate: calciferous rocks

Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the montane belt (potential vegetation: deciduous forests dominated by Fagus sylvatica and closed coniferous forests with Picea abies)

Note: a mild-temperate to subtropical species found on a wide variety of calciferous substrata; common in the Mediterranean-submediterranean belts, rarer at higher altitudes, more helio- and thermophytic than the closely related C. flavescens; widespread throughout the Alps, at low elevations.
