Range & Status

Native. Oceanic Southern-temperate species. Widespread in the Channel Islands and coastal areas of western Britain and Ireland, west of Hampshire to southern Scotland.

Regional Distribution

Still a frequent plant in the Isles of Scilly, on all the inhabited and larger uninhabited

islands. Around the Cornish coast it occurs along the north coast between St. Ives (SW54) and Wadebridge (SW97), north and south of Bude (SS21) and scattered along the south coast.

Habitat & Ecology

Along the cliffs on rocky slopes, semi-fixed dunes, coastal walls and hedges, and along the coastal footpath. It also grows on shingle and occasionally on storm beaches. In Scilly it is a plant of sand and shingle beaches, as well as on dune-grassland and sandy places especially on the uninhabited islands such as Te\'e4n (SV91), Samson (SV81) and the Eastern Isles (SV91).




Many sites are SSSI.
