Native populations of this perennial are found on calcareous soil over limestone rocks in England and Wales. It typically grows in woodland glades and open scrub, by woodland rides and streamsides, in damp grassland and fen, and on scree slopes. Garden escapes can be naturalised in quarries, on roadsides, railway banks and old walls. 0-470 m (Sandbed Gill, Cumberland).
A. vulgaris has increased since the 1962 Atlas, presumably because of the increasing frequency of garden escapes. The native distribution is now totally obscured and all records are mapped as if they were native.
European Temperate element; widely naturalised outside its native range.
