Rosa canina s.str.
A deciduous shrub of well-drained calcareous to moderately acidic soils. Habitats include woodland, scrub, hedgerows, cliffs, river banks, rock outcrops, roadsides, railways and waste ground. It can rapidly colonise open, disturbed sites. 0?550 m (Breadalbanes, Mid Perth).
This is the most widespread and common segregate of the R. canina aggregate. Four `Groups` within the species were described and mapped by Graham & Primavesi (1993). The distribution of the species is probably stable. The name R. canina is often used for other species and hybrid `Dog-roses`; as many such records have been rejected the true plant is under-recorded in some areas, particularly in Ireland.
European Temperate element; widely naturalised outside its native range.
