This has grown into one of our favorite small deciduous shrubs which we grow near our bog garden.  Collected in China on the Sino-British Expedition to Cangshan in 1981 which was one of the first western botanic expeditions to China in modern times.  Copious pink-white flowers on a 4'-6' tall shrub.  Zone 6 at least.

Uncommon evergreen Deutzia with glossy, dark green leaves with a white underside. Early summer brings subtle clusters of small, star shaped white flowers with pronounced golden anthers. From a Peter Cox collection in the Cangshan.
