The perennial wildflower is native to western North America from northeastern California, the Great Basin, and Pacific Northwest; east to Wyoming and Montana (U.S.) and across western Canada to Saskatchewan. 
It grows in seasonally wet areas of habitats including: sagebrush steppe and sagebrush scrub, yellow pine forest, wetland-riparian zones, and moist slopes and meadows of mountains.  It is found at elevations of 200–1,900 metres (660–6,230 ft). 
Dodecatheon conjugens−Primula conjugens is a thick-rooted perennial with narrow oval-shaped leaves around the base. 
Each flower nods with its mouth pointed to the ground when new, and becomes more erect with age. It has five reflexed sepals in shades of magenta or white which lie back against the body of the flower. At the sepal bases is a ring of bright yellow. From the corolla mouth protrude large dark red or black anthers surrounding a threadlike pink stigma. 
The fruit is circumscissile.
