Yellow Mountain Heather is similar to Pink Mountain Heather but has yellowish-green urn-shaped flowers about 3/8″ (8 mm) long. The two may grow together forming a hybrid known as P. xintermedia which has pale-pink flowers. The petals, sepals and stalks are covered with glandular hairs and are very sticky. The sepals seem to gracefully hold the nodding flowerheads. Of the three heathers in the Park P. glandulifora will be found at the highest elevation usually on moist slopes and rocky ridges to 9,000′ elevation.
