There is in Quebec three other species of white stemless (without stem, leaves and flowers come directly from the ground) violets,the one that resembles it the most is the Sweet white violet (Viola blanda), but the latter form stolons (stems, often at the surface, which, rooting, produce other plants, such as on strawberries, for example ), which allows it to extend in full carpet.
The Small white violet (Viola mccloskey) witch has flowers that rise much above the leaves.
The Lance-leaved violet (Viola lanceolata) is distinguished by its much longer than wide leaves.
There is also the Woolly blue violet (Viola sororia) that usually has blue flowers, sometimes has a form with white flowers.
