Rhododendron davidsonianum, the concave-leaf rhododendron,[3] is a species of flowering plant in the heath family Ericaceae that is native to the forests of Sichuan, China, where it lives at elevations of 1,500–2,800 m (4,900–9,200 ft).[4] Growing to 4 m (13 ft) tall and 2.5 m (8.2 ft) broad, it is an upright evergreen shrub. The glossy leaves are lanceolate and up to 6 cm (2.4 in) long. In spring trusses of bell-shaped, pale pink or purple flowers are produced.[5]

In cultivation in the UK, Rhododendron davidsonianum has gained the Royal Horticultural Society's Award of Garden Merit.[3][6] Like most rhododendrons it prefers an acid soil. It is hardy down to −15 °C (5 °F).
