Distribution:
Common and widespread.
Habitat:
Considered native in upland ash woodland around Downham and Twiston and around flushed areas in wooded clough elsewhere in upland parts; widely established in neglected fields and allotments; along roadsides, railway banks, streamsides, riverbanks, woodlands.
Comments:
Readily escaping from cultivation with a considerable proportion of the South Lancashire populations being of horticultural origin. Note the lack of records for the reclaimed arable farmland area between Banks and Longton.
