Small tree, often multi-stemmed, or large bushy shrub. Broadly heart-shaped, toothed mid-green leaves. Pendant yellow catkins in late winter and early spring, before the leaves develop. Edible brown nuts develop later.

Tough and adaptable to many conditions. Thrives on chalky soils.

Responds well to coppicing, traditionally every 7 years, to produce a dense clump of straight stems.

Commercially cultivated for hazelnuts, mostly as named varieties.

Important species for country hedges as it is easy to maintain and also benificial to wildlife.

Coppiced stems are used for traditional fencing and many other purposes.

other notes:
Native to Europe and western Asia. Occurs very commonlly in hedgerows and marginal woodlands. A British native tree.
