Deutzia scabra is a species of flowering plant in the hydrangea family (Hydrangeaceae) native to Japan and introduced to mainland east Asia, Europe, and North America.[1] In its native Japan, it is found from the Kantō region, westward to the islands of Kyushu and Shikoku.[2] Its natural habitat is along forest edges and rocky openings.[3] It is tolerant of disturbance and can be found growing out of stone walls, along roadsides, and in other waste areas.[4]
Deutzia scabra is a deciduous shrub growing 1–2 meters in height.[3] One way it differs from other Deutzia of Japan, is by its somewhat dimorphic leaves: those subtending the inflorescence being sessile and slightly clasping, while leaves lower down the stem are petiolate.[2] It produces panicles of white flowers, blooming from May to July.[3]
The cultivar 'Candidissima' bears double flowers, and is taller than the species at up to 4m (13feet). It is a recipient of the Royal Horticultural Society's Award of Garden Merit.[5] The pink flowered double 'Codsall Pink' has also received the award.[6]
