Hazel (Corylus avellana)

How to Identify Hazel


Botanical Name:

Corylus avellana

Known Hazards:


Could be confused with:

Other species in the Corylus family, of which are similarly used. Linden Tree (Tilia) which has a similar leaf structure but grows to a huge size and doesn’t produce hazel nuts and isn’t poisoness.

Range and Distribution:

UK, Europe, Norway, North and West Asia, similar hazel in North America


Found growing on calcareous soils often in hedgerows and woodlands where it is used for hedging or coppicing.

Physical Characteristics:

The Common hazel is typically found as a shrub reaching 2-8m tall where it’s coppiced, however when it’s left to grow un-coppiced it can reach 15m tall. The bark is grey brown, becoming darker with age and eventually becoming slightly peely, the fresh young shoots are hairy.

The leaves 6-12cm long and across, are rounded with a double serrated margin and hairs on both sides.

The Flowers are formed in early spring before the leaves. The catkins come in two forms, male and female, male 5-12cm long are pale yellow whilst 1-3mm long, bright res, form mostly concealed in the buds.

The 15-20mm spherical, yellow-brown, nut comes in a short leafed husk, in clusters of 1-5 together and will fall to the ground when ripe, September – October.

Folklore, tall tales, and not so folklore:

Hazel has a strong link with poets, literature and gaining wisdom.

Edible Use:

Leaves: green tea, fermented tea, dried tea, wine, smoking foods

Catkin: edible

Green nut: Salads, pasta, feta parcels, milk

Ripe nut: salads, pasta, cakes, pesto, flour, roasted, pickled, salted, soups, milk, oil


The oil of hazel is referenced as being used to treat infection of threadworm or pinworm in young children.

You have to get out early to collect these nuts before the squirrels get them, find a spot where you know they are and return weekly when you expect them to come in to season around early September, alternatively they can be pickled straight from the tree and used fresh. One of the few nuts that taste brilliant straight off the tree like this.

Although we only have one recipe in this book including hazel I have included it above all other nuts producing trees as it produces the one wild nut I pick on a regular basis (when they’re green and can beat the squirrels to them). I then use this nut in any recipe that calls for either fresh or crushed nuts of any kind.
