Viola riviniana, the common dog-violet, is a species of the genus Viola native to Eurasia and Africa. It is also called wood violet and dog violet. It is a perennial herb of woodland edges, grassland and shady hedge banks. It is found in all soils except acid or very wet.
It is a perennial, flowering from April to June.
Viola riviniana was voted the county flower of Lincolnshire in 2002, following a poll by the wild plant conservation charity Plantlife.
Its leaves are usually hairless.
It is the food plant of the pearl bordered fritillary, small pearl-bordered fritillary, silver-washed fritillary and high brown fritillary butterflies.
This species hybridises with early dog-violet (V. reichenbachiana) to produce Viola × bavarica.
