Subalpine to alpine slopes, and occasionally level wetlands. Flowering May–Sep. 900–2900 m. BW, Casc, ECas, Owy. CA, ID, WA; north to Yukon, east to WY, southeast to AZ. Native.

Where P. empetriformis and P. glanduliflora are sympatric, hybrids are occasionally found (P. × intermedia). Whether or to what degree these hybrids are fertile has yet to be determined.
