It is endemic to Colorado in the United States, where it occurs only in the vicinity of Pagosa Springs in Archuleta County.

It is white in color with tiny purple dots, sometimes so many that they give the flower a purplish tint.

[2] This species is threatened with direct mortality and loss of habitat as the human population of Archuleta County swells.

More land nearby will be affected by associated development activities, such as the construction of roads and utilities such as power lines.

About 9% of the plant's habitat is on highway right-of-ways which are affected by herbicide application and the introduction of groundcover, such as exotic grasses.
