State Rank Reason (see State Rank above)
Viola purpurea occurs in the southwest and south-central portions of Montana, which is at the edge of its distribution in the western United States (FNA 2015). Plants grow in gravelly soils of meadows, grasslands, and exposed slopes from the montane to subalpine zones. Since 1899 many populations have been documented, but observation data is getting old. Habitat appears to be stable and not a limiting factor. Threats have not been identified. Current information on population locations and sizes, threats, and habitat requirements is needed to better assess its status.
