Common hazel is a shrub or small tree from the birch family (Betulaceae), botanically accepted as Corylus avellana L. The plant usually reaches 2 to 5 metres in height, forms a dense crown, and is able to spread through root suckers.
The stem is slender, with smooth greyish to ash-coloured bark. Common hazel is a monoecious species, meaning that male and female flowers occur on the same plant. The male flowers are arranged in catkins and appear before the leaves, usually from February to April.
The leaves are large, with a broad heart-shaped base, a pointed tip, and a finely hairy surface. The fruit is the hazelnut — a hard brown nut enclosed in a green husk.
Common hazel is widely distributed in Bulgaria. It grows in deciduous forests, on slopes, woodland edges, and in scrubland.
