'''''Deutzia''''' is a [[genus]] of about 60 species of [[shrub]]s in the family [[Hydrangeaceae]], native to eastern and central [[Asia]] (from the [[Himalaya]] east to [[Japan]] and the [[Philippines]]), and [[Central America]] and also Europe. By far the highest species diversity is in China, where 50 species occur.
The species are shrubs ranging from 1-4 m in height. Most are [[deciduous]], but a few subtropical species are [[evergreen]]. The [[leaf|leaves]] are opposite, simple, with a serrated margin. The [[flower]]s are produced in [[panicle]]s or [[corymb]]s; they are white in most species, sometimes pink or reddish. The [[fruit]] is a dry [[capsule (fruit)|capsule]] containing numerous small [[seed]]s. Identification of the species is very difficult, requiring often microscopic detail of the leaf hairs and seed capsule structure.

===Cultivation and uses===
[[Image:Deutzia scabra plena.jpg|left|thumb|''Deutzia crenata'' 'Plena', a double-flowered cultivar]]
Deutzias are commonly grown as [[ornamental plant]]s for their white flowers. Many [[cultivar]]s and [[Hybrid (biology)|hybrids]] have been selected for garden use, including selections with double flowers.
For example, ''Deutzia'' x ''lemoinei'' is a hybrid of ''D. gracilis'' and ''D. parviflora''.
Identification can be difficult, and in particular, many of the plants in cultivation sold as ''D. scabra'' are actually ''D. crenata'' (Huxley 1992). Some species are sometimes known as "Pride-of-Rochester" in cultivation. <br clear = left>
