Corylopsis-commonly called winter hazel–is a deciduous shrub that bears bell-shaped fragrant yellow flowers borne on pendent racemes in spring before the young leaves emerge. Corylopsis has a spreading habit; it grows from 5 to 15 feet tall and is commonly wider than it is tall. Leaves are pale to dark green.
Corylopsis is a good choice for a woodland garden or in a shrub or mixed border. Planted against a backdrop of evergreens the late winter, early spring blooms will be well displayed.
Corylopsis grows best in partial shade in humus-rich, well-drained soil. Corylopsis should be planted where it is protected from wind.
Corylopsis is a genus of about 10 species of deciduous shrubs and small trees native to woodlands and scrub in the Himalayas, China, and Japan.
