(Before 1980) This small azalea blooms in late spring or early summer with flowers that are shades of orange to red. It is sometimes mistaken for the Flame Azalea, but the plants in the Glen are smaller and not as vigorous as the other azaleas. It is located in the area at the north end of the Kellam Trail, in a section (now obscured) that was rock-lined to enclose a planting of azaleas. It is beside R. arborescens.
