Field observations suggest that Rhododendron bureavioides should be treated as a distinct species. It differs in having a bistrate indumentum.

Rhododendron bureavii ( anglais )

fourni par wikipedia EN

Rhododendron bureavii, the Bureau rhododendron[2] (Chinese: 杜鹃; pinyin: xiùhóng dùjuān),[3] is a species of flowering plant in the heath family Ericaceae. It is native to western Sichuan and northern Yunnan, China, where it lives at altitudes of 2,800–4,500 m (9,200–14,800 ft).[3]

Growing to 2.5 m (8.2 ft) tall and broad, it is an evergreen shrub. The leathery leaves are elliptic to obovate-oblong, 6–14 by 2.5–5 cm in size. New leaf growth is covered in a fuzzy brown indumentum that remains on the underside of the mature leaves. In mid-spring, the Bureau rhododendron produces trusses of bell-shaped flowers. The flowers are pink in bud, fading to white when open, with purple spots on the interior.[4]

In cultivation in the UK, Rhododendron bureavii has gained the Royal Horticultural Society’s Award of Garden Merit.[2][5] Like most rhododendrons it prefers an acid soil and dappled sunshine. It is hardy down to −20 °C (−4 °F).
