Common hazel (Corylus avellana) is a deciduous woody perennial typically forming a multi-stemmed shrub with upright, flexible branches emerging from the base. The stems are smooth and often slightly twisted, supporting broad, rounded leaves during the growing season. Also referred to as European hazel, the species is native to Europe and western Asia and commonly occurs in mixed woodlands, forest edges, and hedgerows.
Corylus avellana is biologically significant for its early seasonal flowering and production of edible nuts. The plant exhibits strong coppicing ability, allowing repeated regeneration from the base after disturbance. This trait contributes to its long-term persistence and adaptability. In its natural form, common hazel emphasizes flexibility, regenerative growth, and its role as a key understory species within temperate forest ecosystems.
Common Hazel has a typical overall cultivated height between 12’-20’ (3.66-6.1 m), maximum wild heights of 40’-50’ (12.19-15.24 m), and spread diameter of 8’-25’ (2.44-7.62 m).
