Deciduous shrubs and small trees found in scrub and woodland in China, Taiwan and Japan. They have alternate, simple, ovate, toothed pale to dark-green leaves. Pendent racemes of bell-shaped, fragrant yellow flowers are produced in Spring before new leaves emerge.

Unlike Corylus/ Hazels, Winter Hazels are lime-hating and require acidic/ ericaceous soil and feed.
Particularly useful species for bonsai are Corylopsis pauciflora and C.spicata.
