It is a large shrub or small tree endemic to Corsica, Sardinia, and Sicily where it is associated with sunny, open landscapes and poor, stony soil. It is a very common constituent of the garigue plant communities, Mediterranean shrubby vegetation, around the lower slopes of Mount Etna, hence its Latin specific epithet aetnensis.
