'''''Corylopsis''''' is a genus of nearly 30 species of [[shrub]]s in the witch hazel family, [[Hamamelidaceae]], native to eastern [[Asia]] with the majority of species endemic in [[China]] but with some also in [[Japan]], [[Korea]], and the [[Himalaya]].

They grow to 2-6 m tall, and often with a crown wider than tall. The [[leaf|leaves]] are ovate with an acute apex and a serrated margin, 4-20 cm long and 3-15 cm broad. The [[flower]]s are produced in late winter in pendulous [[raceme]]s 3-9 cm long with 5-30 flowers; each flower has five pale yellow petals, 4-9 mm long. The [[fruit]] is a dry [[capsule (fruit)|capsule]] 10-12 mm long, containing two glossy black [[seed]]s.

===Cultivation and uses===
[[image:Corylopsis_Pauciflora_A.jpg|thumb|Corylopsis Pauciflora]]They are often grown in gardens for their very early, yellow flowers. They do have weak branches though, which are often damaged by heavy snow loads. ''Corylopsis'' prefers to grow in semi-shade or shade, protected from strong winds. It grows best on humus-rich soils. The sweetly scented flowering branches keep well in a vase. ''Corylopsis'' also makes good bonsai plants, especially ''C. pauciflora''.

 Deciduous shrubs, rarely trees: lvs. alternate, strongly veined, dentate: fls. in nodding racemes with large bracts at the base, appearing before the lvs., yellow; calyx-lobes short; petals clawed, 5; stamens 5, alternating with entire or 2-3-parted short staminodes; styles 2; ovary half-superior, rarely entirely superior: fr. a 2-celled, dehiscent, 2-beaked caps., with 2 shining black seeds.—About 12 species in E. Asia and Himalayas.
 These are low ornamental shrubs, with slender branches and pale bluish green distinct foliage; all are very attractive in early spring, when covered with numerous nodding spikes of yellow, fragrant flowers. Not hardy north of New York, except in sheltered positions. They grow best in peaty and sandy soil. Propagated by seeds sown in spring, best with slight bottom heat, and by cuttings of half-ripened wood in summer under glass; also by layers, rooting readily in moderately moist, peaty soil.
