Most distinct amongst the rowans, this Chinese/Burmese species, closely related to S. insignis, has comparatively huge foliage composed of great fat, thick textured, glossy, dark green leaflets with pale glaucous undersides. Large flat heads of white flowers are followed by small pink fruits. Makes a large shrub or small tree eventually. Quite striking! A Wickendon collection from the Dulong, NW Yunnan.
