Edaphic preferences: Ca/Si; Si; Ser. Chorotype: Paleosubtropical. Global distribution (POWO, 2022): native to Afghanistan, Albania, Algeria, Azores, Baleares, Canary Is., Corse, Cyprus, East Aegean Is., Eritrea, Ethiopia, France, Greece, Iran, Iraq, Italy, Lebanon-Syria, Libya, Madeira, Morocco, Pakistan, Palestine, Portugal, Spain, Tunisia, Turkey, Yemen, ex-Yugoslavia.

Introduced into Lombardy. Recorded by mistake in Emilia Romagna. Notes: species with a large Mediterranean and Paleotropical (montane) range.
