Its scientific name derives from the Greek kràtaigos which means strength and robustness, due to the hardness of its wood. It is widespread throughout Italy (even in the islands), from flat areas up to 1,500 m of altitude; it is common among the shrub species of the undergrowth, at the edge of the woods or in the wooded pastures, it manages to colonize the grassy slopes.
