Discussion | Cliffs and subalpine to alpine slopes. Flowering Jul–Aug. 300–3000 m. BW, Casc. WA; north to AK, east to WY. Native. See comments for Phyllodoce empetriformis. |
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. |
