The plant is found in woods, open scrub, and grassland including on chalk. Its world distribution is broadly endemic to Europe: from the British Isles in the west to European Russia and the Caucasus in the east; and from the coastal region of Norway to 65°N, down to the whole of Italy and the Balkans excluding most of Greece. There are scattered outliers in Spain, Turkey, and North Africa. (Codes)
