Corylopsis sinensis is a vigorous, medium sized, deciduous, spreading shrub. Its dark green leaves are broadly ovate, alternate and simple with bristly serrated edges, deeply veined, up to  15cm long and are glaucous on their undersides. Its bark is brown in colour with a smooth texture. Its fragrant pastel yellow flowers are cruciform in shape, borne in pendant racemes which are up to 8cm long and appear on bare stems. The fruit is a small, dry, 2 valved capsule.

Corylopsis sinensis, commonly known as Chinese Winter Hazel, is native to west and central China. The plant was described in 1906 by William Botting Hemsley. It was introduced into Britain by Ernest H. Wilson in 1900 from China.

The etymological root of the binomial name Corylopsis is derived from the Greek ‘korylos’ Hazel and ‘oyis’ ‘appearance’, in reference to the leaves’ similarity to those of the Hazel. Sinensis is derived from the Latin meaning ‘from China’.

The landscape architect may find Corylopsis sinensis useful as an attractive early spring flowering shrub. To be best appreciated it needs space. It also would make a good screening or informal hedging plant.

Ecologically, Corylopsis sinensis does not have much wildlife value  in the UK.

The Royal Horticultural Society has given Corylopsis sinensis var. sinensis their prestigious Award of Garden Merit in 1993.

Corylopsis sinensis prefers moist, humus rich, well-drained soils. It tolerates most pH of soil, although it prefers acidic soils.

Corylopsis sinensis requires little maintenance.
