Where it grows wild

Specimen labels record laurel forest (El Cedro on El Hierro, Los Tilos on La Palma) and 'N-facing rock crevices in large gulley' (Morocco). Other records come from cliffs and ravines on Tenerife and El Hierro.

The few records with an elevation fall between 700 and 1300 m, median 850 m. This is the cloud and laurel forest belt of the western Canaries.
