Hazel

RHS Genus Guide
Hazels are a versatile group of deciduous trees and large shrubs. They are probably best known for their yellow, dangling catkins on bare branches in early spring, followed by edible nuts in autumn. The common hazel (Corylus avellana) is excellent for wildlife gardens, hedgerows and woodland settings.

Botanical name: Corylus

Common name: hazel

Appearance

Hazel species vary in size, typically reaching 3-8m tall, with rounded leaves that turn yellow in autumn. They can make a graceful arching form if kept coppiced and make the perfect setting for spring flowers. Some varieties have deep red leaves and others have interesting, twisted branches.

Preferences

They thrive in well-drained, fertile soil in sun or partial shade. They appreciate shelter from strong winds and do well in mixed hedgerows or naturalistic planting schemes.

Dislikes

Hazels dislike waterlogged soils and may struggle in very dry or exposed sites. Heavy pruning at the wrong time can reduce nut production.

Did you know?

In folklore, hazel was a symbol of wisdom, and hazel twigs are used to this day for the traditional art of dowsing – finding water hidden underground.
