Rhododendron racemosum, the racemose rhododendron[2] (Chinese: 腋花杜鹃; pinyin: yèhuā dùjuān),[3] is a species of flowering plant in the heath family, native to forest and grassland at 1,500–3,500 m (4,900–11,500 ft) in northwestern Guizhou, southwestern Sichuan, and Yunnan, China.[3]

Description

It is an upright evergreen shrub growing to 2 m (6.6 ft) tall by 1.5 m (4.9 ft) broad. In early spring it bears masses of pale or deep pink trumpet-shaped flowers, each with up to 10 prominent stamens.[2]

Cultivation

In cultivation in the UK Rhododendron racemosum and the cultivar ‘Rock Rose’[4] have gained the Royal Horticultural Society’s Award of Garden Merit.[2][5] It is hardy down to −20 °C (−4 °F) but like most rhododendrons it requires a sheltered spot in dappled shade, and an acid soil enriched with leaf mould.
