Upright and stout-branched large evergreen shrubs or small trees. The leaves have a thin brownish indumentum on the lower surface. The pale yellow to yellow flowers (mid-spring) are in a large round inflorescence and often have a large reddish blotch in the throat.The beautiful and attractive foliage combine to make this one of the most popular and highly sought after species. Rarely available, it is rather slow-growing and difficult in cultivation, requiring shade from the hot afternoon sun and a cool, acidic and extremely well-drained soil. Native to west-central & NE Yunnan, China where it occurs in various montane habitats from 10,000 to 13,000 ft.
