Article from Bean’s Trees and Shrubs Hardy in the British Isles:

A shrub of bushy habit up to 12 ft high; young shoots downy; year-old bark peeling, glabrous. Leaves narrowly oval, tapered at both ends, finely toothed except towards the base, 2,5 to 6 mm long, 12 to 20 mm wide, furnished both above and below with pale, bristle-like, minute hairs, but especially dense and grey with them beneath. Flowers white, 2 to 2.5 mm in width, borne during early June in racemes of three to eleven; flower-stalk and calyx hairy, purplish; style downy towards the base, shorter than the stamens; stigmas separate. Fruits top-shaped.

Native of Szechwan, China,’ and bordering parts of N.E. Yunnan; introduced to France by the missionary Farges in 1894 and described from plants in the collection of Maurice de Vilmorin, and thence to the Royal Botanic garden at Kew in 1897. It is one of the prettiest of the species, and one of the first to come into flower, in late May or early June. It is closely allied to Philadelphus incanus and Philadelphus subcanus.
