There are localities for northern Algeria , Spain , France , Belgium , the Netherlands , Germany , Austria , Switzerland , Italy (including Sardinia , Sicily ), Poland , Czechoslovakia , Hungary , the former Yugoslavia , Bulgaria , Romania , Albania , Moldova , Greece , Turkey , southern Ukraine , and Crimea .

The mountain germander tolerates heat and drought very well. In Central Europe it is a character species of the Xerobromion association, but also occurs in plant communities of the Mesobromion, Steipion calagamgristis, Seslerion or Erico-Pinion associations.
