Weigela // is a genus of between six and 38 species 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 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 were already well known to locals.[clarification needed]
The British Weigela national collection is held at Sheffield Botanical Gardens; along with the national collection of the closely related genus Diervilla. The German Weigela national collection, Sichtungsgarten Weigela, is in Buckow, Maerkische-Schweiz.

Several of the species are very popular ornamental shrubs in gardens, although species have been mostly superseded by hybrids (crosses between W. florida and other Asiatic species). The following cultivars have gained the Royal Horticultural Society's Award of Garden Merit:
Weigela florida 'Pink Princess'Edit
Weigela florida 'Pink Princess' is a popular cultivar of Weigela florida, a shrub native to northern China, Korea, and Japan, that flowers profusely. It is a hardy plant, easy to grow and maintain. It grows to a height and width of up to 1.5–1.8 m (5–6 ft) in appropriate conditions, and is thus more compact than the normal Weigela florida, which makes it a more versatile shrub. It is attractive to hummingbirds and bees.
