Primula veris (Cowslip)
A perennial herb of well-drained, herb-rich grasslands on mesic to calcareous soils; less commonly on seasonally flooded soils, in scrub or woodland rides and edges, and on calcareous cliffs. 0-750 m (Knock Ore Gill, Westmorland), and exceptionally at 845 m (Great Dun Fell, Westmorland).
P. veris suffered a marked decline between 1930 and 1980 due to the ploughing or agricultural improvement of grassland. It has, however, recently become more frequent on road verges sown with this species or with wild-flower mixtures. The current map shows little change from the 1962 Atlas.
Eurosiberian Temperate element.
Calcareous grassland (includes lowland and montane types)
