Lobelia urens has the English name of heath lobelia or acrid lobelia. It has a Lusitanian distribution running from Morocco along the Atlantic Coast to Belgium. It can be found in the islands of south Europe: Madeira, Tercia, Falia, Gibraltar. In Spain it is found in grazed pasture of upland valleys between 600 and 915 metres high. In Portugal it exists along the coastal plain, passing into the wet northern province valleys up to 800 metres. In north France it is found in lowland coastal areas. It is rare in Britain and found in South and South West of England in lowland areas up to 210 metres high. It is not threatened in Europe.
