Rhododendron griersonianum is a species of flowering plant in the family Ericaceae.

[1] It is native to western Yunnan (China) and Myanmar, where it grows in mixed forests and thickets at altitudes of 1,600–2,700 m (5,200–8,900 ft).

This evergreen shrub reaches an average height of 1.3 m (4.3 ft).

This highly distinctive species was introduced to western horticulture in 1917 by the Scottish planthunter George Forrest, who later commented: "Extremely local; essentially a plant of the open, seldom, if ever, seen in the shade, though the glades where it is seen at its best are always more or less sheltered.

In addition to the striking beauty of the flowers it is a most shapely shrub.
