Hazel is a colonizing species that grows along watercourses, ravines and valleys. They grow in isolation, forming stands, groves or acting as companions to other species.

The Hazel is a shrub branching out from the base or a small tree that reaches a height of 8-10 m.

Its crown is broad and dense, its bark reddish in colour at the outset and greyish at full maturity. The leaves are deciduous, plain, alternate, comparatively large, heart-shaped, round or broadly oval, up to 15 cm in length, double-toothed, finishing in a pointed tip.

Hazel are monoecious, meaning that the separate male and female flowers are found on the same tree, blooming on bare branches from the end of winter right into the beginning of spring (March-April), before the leaves appear.

The eye-catching male flowers are arranged in long hanging filaments called catkins that disperse pollen with even the slightest breeze. The female flowers, on the other hand, are more discreet with red buds that bloom just above the male catkins. These flowers, once pollinated, develop into the oval fruit or hazelnut, that have a partial shell with a papyrus-like aspect resembling a helmet. Hazel is very flexible, therefore its branches or strips of wood are used for basketry, wooden casks, as well as crafting sticks and canes.

Its specific epithet (botanical name) actually comes from Avella Veccia (Southern Italy) or Avellina (Eastern city of Naples, where it was widely cultivated) and called Nux Avellan by the Romans.
