About

Rhododendron sinogrande (凸尖杜鹃) is a species of flowering plant in the family Ericaceae. It is commonly called the great Chinese rhododendron, and is native to alpine regions at 2,100–3,600 m (6,900–11,800 ft) in southeastern Xizang and western Yunnan in China and in northeastern Myanmar.

How to grow it

In cultivation in the UK Rhododendron sinogrande has gained the Royal Horticultural Society's Award of Garden Merit. It is hardy down to −10 °C (14 °F) but like most rhododendrons it requires a sheltered spot in dappled shade, and an acid soil enriched with leaf mould.
