Family

Hamamelidaceae

Botanical Name

CORYLOPSIS spicata

Plant Common Name

Spike Winterhazel

General Description

The picturesque branches of spike winterhazel produce hundreds of pendent, fragrant yellow blossoms in spring. This open, lightly spreading deciduous shrub is native to Japan. It is quite slow-growing but reaches a substantial size when mature.

A profusion of short, drooping clusters with six to twelve fragrant, yellow blossoms appear in spring before the leaves appear. Each bloom has conspicuous pollen-carrying anthers of reddish purple. Deep blue-green oval leaves with a purplish cast emerge after flowering. In a cool, moist autumn they will turn yellow but cold fall weather will cause them to quickly turn brown. Spike winterhazel fruits are dry, tan capsules.

Grow winterhazel in partial shade and slightly acid to neutral soil that is fertile and moist but well-drained. Provide more shade or water in areas with hot, dry summers. Amend heavy soils with organic matter to make it more friable. Refrain from planting this shrub in windy locales. This is an attractive spring accent shrub for large mixed shrub borders or foundations. A planting of early-blooming spring flowers at its base will draw even more attention to its interesting spring flowers.
