Value of species
Viola lutea subsp. lutea is native to central and north-western Europe, from the British Isles to Austria; another subspecies occurs further east, from Hungary to the Balkans. Within Great Britain, V. lutea is found only in upland areas north of a line drawn between the Severn and Humber estuaries; it ranges in altitude from 200 metres (660 ft) in Derbyshire to 1,070 m (3,500 ft) in Breadalbane. In Ireland, its distribution is more scattered geographically, and ranges vertically from sea level in County Clare to 380 m (1,250 ft) in the Wicklow Mountains.
