Rhododendron adenogynum is an evergreen shrub of the heath family (Ericaceae), native to high altitudes (3,200 to 4,200 m) in southwest Sichuan, southeast Tibet and northwest Yunnan. It is hardy but rarely grown outside specialist collections, so growing it means treating it like other high-altitude rhododendrons: cool, moist, acidic conditions and good drainage.

About
Rhododendron adenogynum (simplified Chinese: 腺房杜鹃; traditional Chinese: 腺房杜鵑; pinyin: xiànfáng dùjuān) is a species of flowering plant in the heath family Ericaceae, native to southwest Sichuan, southeast Xizang, and northwest Yunnan in China, where it grows at altitudes of 3,200–4,200 m (10,500–13,800 ft). This evergreen shrub grows to 1–2 m (3.3–6.6 ft) in height, with leathery leaves that are lanceolate to oblong-lanceolate, 6–12 by 2–4 cm in size. The flowers are white to pink, with crimson spots.
Though hardy, it is rarely seen in cultivation outside of specialist collections.
