A deciduous perennial herb found as a well-naturalised garden escape on and around chalk cliffs at Rottingdean and Seaford (E. Sussex) and on the sea front at West Bay (Dorset). It grows with alien populations of Frankenia laevis at both localities, and is apparently spread by gulls. Lowland.
This species was first recorded in the wild at Rottingdean in 1979, and in West Bay in 1993. It was not described from Sicily as a distinct species until 1980.
Native of Sicily.
