Viola labradorica, commonly known as Alpine dog violet, Alpine violet, American dog violet, dog violet, and Labrador violet, is a perennial native to eastern Canada, Greenland, and the United States. The plant sold as Viola labradorica by nurseries is Viola riviniana.
A purple-leaved form of the European dog-violet (Viola riviniana 'Purpurea Group'), is often sold by nurseries as Viola labradorica. The true Viola labradorica is almost never sold.
Viola riviana is grown as a flowering groundcover in gardens and as a house plant. It can become naturalized, or even an invasive species, when planted near adjacent native plant habitats and natural-wildland ecosystems.
