Crenate Pride-Of-Rochester

(Deutzia crenata)



Deutzia crenata is a species of flowering shrub in the hydrangea family (Hydrangeaceae). It is native to Japan, where it is common and found throughout the country. Its natural habitat is in forest edges and cliffs. It has been commonly cultivated outside its native range, and has naturalized from plantings in China and North America. Deutzia crenata is a deciduous shrub. Its leaves are opposite, dentate, and rather thickened. In contrast to the similar Deutzia scabra, its leaves are not notably diamorphic and are found on short petioles throughout the length of the stem. In addition, all of the filaments of Deutzia crenata are toothed.In Japan, this species produces flowers from May to July. A form with doubled flowers (forma plena) is popular in gardens Deutzia (/ˈdjuːtsiə/ or /ˈdɔɪtsiə/) is a genus of about 60 species of flowering plants in the family Hydrangeaceae, native to eastern and central Asia (from the Himalayas 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 (3 ft 3 in – 13 ft 1 in) in height. Most are deciduous, but a few subtropical species are evergreen. The leaves are opposite, simple, with a serrated margin. The flowers are produced in panicles or corymbs; they are white in most species, sometimes pink or reddish. The fruit is a dry capsule containing numerous small seeds. Identification of the species is very difficult, requiring often microscopic detail of the leaf hairs and seed capsule structure. Deutzia is named after the 18th century Dutch patron of botany, Johan van der Deutz. The deutzias are fairly new to gardens: the exception, D. scabra, was noticed in Japanese gardens by Engelbert Kaempfer (1712) and Carl Peter Thunberg (1784) but not actually seen in Europe till the 1830s; two-thirds of the species noted in the R.H.S. Dictionary were gathered in from the wild during the 20th century.
