Native to Europe-Rank Endangered in Great Britain: Distribution and habitat Native to Europe, this species has a submediterranean / subatlantic distribution. In the British Isles it mostly occurs near the coast of England, Wales, Scotland and Ireland, but also sporadically inland. It is found in sandy or gravelly, often acidic, soils in arable fields, on wasteland and on walls, as well as poor dry pastures on the coast, and on sand dunes in the Channel Islands.[4] Status This plant has been in long-term decline, especially in the more northern parts of Europe, and is no longer present in many inland sites in Britain and Ireland, with a population reduction of 80% in the last ten years reported in 2006. This may be due to changes in agriculture practices, or it may perhaps be affected by climate change. It is listed as a UK Priority Species, and the Great Britain Red Data List ranks it as endangered.[5] (link added by Steve Conger)
