Flowering

Habitat

Rocks, fine debris, gravel (limestone and limestone schists) from 2000 to 2800 m above sea level.


Distribution

Sub-endemic species of the Western Italian and French Alps, present from Liguria to Val d'Aosta and in the central Apennines of the Marche region on Monte Vettore (Sibillini Mountains).


Etymology

The name of the genus from the diminutive lat. campanula, "small bell". The specific epithet from lat. alpestris, of the Alps: it indicates not so much the high altitude (alpinus) as the character of the rocky and rugged habitat where the vegetation is often small.


Properties and uses

Like many other species of the genus Micromeria, it can be easily grown both in pots and rock gardens.


Protection

Species with total protection in the Piedmont Region (L.R. n. 32 of 2 November 1982: "Norms for the conservation of the natural heritage and the environment") in the Provinces of Cuneo, Turin and Novara: it is forbidden to pick, remove, damage, keep parts of it, as well as to trade it both fresh and dry.



Endemism: endemic species are animal or plant species living exclusively in a given territory. When this is very limited, we speak of " restricted" endemisms. "Endemic" is not necessarily synonymous with "rare": rare species may have few individuals distributed in large areas, an endemic species may also be abundant in a given area, but be limited to that single territory.
