Weigela
''Weigela'' 〔''Sunset Western Garden Book,'' 1995:606–607〕 is a genus of between six and 38 species〔All of the species listed in the 'Selected species' section are accepted by The Plant List, but most are still under review, and therefore subject to changes in status. 〕 of deciduous shrubs in the family Caprifoliaceae, growing to 1–5 m (3-15') tall. All are natives of eastern Asia. The genus is named after the German scientist Christian Ehrenfried Weigel. The leaves are 5–15 cm long, ovate-oblong with an acuminate tip, and with a serrated margin. The flowers are 2–4 cm long, with a five-lobed white, pink, or red (rarely yellow) corolla, produced in small corymbs of several together in early summer. The fruit is a dry capsule containing numerous small winged seeds. ==Garden history== The first species to be collected for Western gardens, ''Weigela florida'', distributed in North China, Korea and Manchuria, was found by Robert Fortune and imported to England in 1845.〔 Following the opening of Japan to Westerners, several ''Weigela'' species and garden versions were "discovered" by European plant-hunters in the 1850s and 1860s, though they may have already been known to locals.〔Mark Nesbitt, ''The Cultural History of Plants'', 2005:284; Ran Levy-Yamamori, Ran Levy, Gerard Taaffe, ''Garden plants of Japan'', 2004, ''s.v.'' "Weigela hortensis"〕 The British ''Weigela'' national collection is held at Sheffield Botanical Gardens; along with the national collection of the closely related ''Diervilla'' genus.〔 The German ''Weigela'' national collection, Sichtungsgarten Weigela, is in Buckow, Maerkische-Schweiz.
