Family:
Formerly often classified as belonging to the Betulaceae (Birch family), but was then given its own family: Corylaceae (Hazel family).

Synonyms:
Common Hazel, Hazelnut, European Filbert, Cobnut.

Hazel is a native British tree and occurs throughout England, Scotland, Wales and Ireland, except for the Shetland Isles. It also grows throughout Europe except for the far North.

Hazel (Corylus avellana)

Analysis if pollen deposits in dated peat strata has confirmed that Hazel was on of the dominant plants of the undergrowth in Pine Forests after the Ice Age. This makes sense of the fact that one of the ancient names for Scotland was "Caledonia", meaning Hill of the Hazel ('Col' or 'Cal' is the Celtic word for Hazel and 'dun' means hill - as in our modern 'dunes').

Name:
'
Corylus' was the Greek name for a Hazelbush.
'Avellana' is thought to refer to Avella Vecchia in Southern Italy.

Hazel (Corylus avellana) - nutsCultivation:
Propagation can be by seed, tip-layering or radical suckers and cutting. Hazels will grow in shade as well as in full sunlight and are  lime-tolerant. Grows 15 ft in 20 years. Hazel take extremely well to being coppiced and if done properly this practice can prolong the life of the Hazel considerably, since it normally is a relatively short-lived tree. Hazels were often cut every 7 years and could form enormous stools eventually.

Uses:
The nuts were of course eaten. It is rich in fatty oils and vitamins. Weight for weight they contain 50% more protein, 7x more fat and 5x more carbohydrate than hen's eggs.
The oil is multi-usable and has been employed for cooking or dressing salads, as well as in oil paints, as a machine lubricant and in making perfumery and cosmetics.
The wood of the Hazel is not long lasting, but since Hazel rods are extremely pliable (and abundant), they have been used for a great variety of purposes: basket work, wattle and daub frames, hurdles to pen sheep and other fencing panels, thatching spars, coracle frames (Coracles are the Celtic basket like boats), bender poles (a bender is a temporary tent as used by travelers, peace protesters and so on), hoops, fishing rods, walking sticks, broom handles and so on
Forked hazel twigs are traditionally used for water divining.

Hazel Medicine:
The Hazel has not been as widely used in herbal medicine as some of our other trees. Nevertheless the dried or fresh leaves have a stimulating effect on the circulation and bile production, as well having some diuretic properties. The leaves have used in the past in some patent medicines for gall and liver disorders. The 17th century herbalist Nicolas Culpepper wrote:
"The parted kernels made into an electuary or the milk drawn from them with mead or honied water is good to help an old cough, and a little pepper put in draws rheum from the head. The dried husks and shells to the weight of two drams, taken in wine, stays laxness and women's courses, the skin answers the same purpose."
Hazel bark has been used as a substitute for Witch Hazel (see below). This must work fine to some extent, since all tree barks contain relatively large quantities of tannins. I would love to hear from anyone with experience on this subject.

The long male Hazel Catkins are sometimes called 'lambs tails' The female catkins are small and reddish on the same branch

History and Treelore:

  • Before the second World War, it was still quite common for people to harvest the nuts. Like many other rural customs, this was often a communal affair with whole villages going out and about. Timing is very important. Too early and the nuts will lack taste and will not store long. Too late and the jays and squirrels will have all. People would take picnics and a drink of ale or cider. "Nutting" used to be a euphism for "courting", and this expression may originated in the fact that gathering nuts in the woods and shrubland gave lots of opportunity for making contact with the object of one's affection.

  • The Hazel used to be the only proper edible Nut tree in Northern Europe and this gave it a special place in folklore and tradition. The nut was seen as powerful symbol of Wisdom. "All in a nutshell." Wisdom comes from the old Anglo-saxon root "wissen" which has a double meaning of 'knowledge' as well as 'growing'. Wisdom was seen as "growing power", it was seen as a living process rather than 'dogma'.

  • Hazel was an important tree in Irish mythology. It represented the letter 'Coll', which was the ninth letter of the Irish Bardic Ogham alphabet. It gave its name to a God named Mac Coll (son of Hazel), who according to Keating's history of Ireland was one of the earliest rulers Ireland, his brothers being Mac Ceacht (son of the plough) and Mac Greine (son of the Sun). They celebrated a triple marriage with the Triple Goddess of Ireland: Eire, Fodhla and Banbha.

Other species and varieties:

  • Corkscrew Hazel (Corylus avellana 'Contorta') - Differs from the common Hazel in that the twigs and branches have amazing twists and contortions. A slow growing tree, which is a popular choice as an ornamental garden tree, because it looks stunning in the late winter/early spring with its catkins. Often easily available at garden centres.

  • Filbert or Kentish Cob (Coryllus maxima) - A native of Western Asia and South-Eastern Europe, which was introduced here because of its larger nuts. Like the Common Hazel this is a small tree eventually growing up to 10 metres high. The leaves and the male catkins are larger. Other differences are that the nut is more elongated and the cup around it is longer.

  • Hybrids between the Common Hazel and the Kentish Cob are seen.

  • Corylus maxima 'Purpurea' is a purple-leaved variety, which is frequently grown for its foliage.

  • Turkish Hazel or Turkish Filbert (Corylus colurna) - In comparison with the others, this is the 'giant' member of the Hazel family and grows up to 80 ft high in a pyramidal shape in its native lands. Everything is bigger on this tree, the bark has coarser fissures, the hazels appear in clusters and the branching is very level.. It was introduced to Britain along with the Horse Chestnut in the 17th century . It is a sun-loving tree, which thrives on hot summers and cold winters. Consequently it does not fruit well in Britain and usually only grown as an ornamental in parks and gardens. 

  • Witch Hazels (Hamamelis species). When European settlers arrived in North America they mistook what is now known as Hamamelis virginiana or Witch Hazel as a Hazel because of the similarity in leaf and bushy habit. It turned out to have great gifts as a medicinal plants (We offer a page where you can read the entry for Witch Hazel from "A Modern Herbal" by Mrs. M. Grieve and Mrs. C.F.Leyel, published in 1931. Obviously things have moved on since then, yet this book is still often unsurpassed in its scope and depth of traditional knowledge. The page pops up in a new window. Close it to return to the Tree Gallery).
    The American Witch Hazel was introduced to Britain in the 1740's, but the nut does not bear seeds in the UK. In Germany however, it has been cultivated widely for the medicinal tonic properties of its bark and leaves.

    Witch Hazels have become popular as ornamental trees in Parks and gardens due to their autumn or winter flowering (Yellow flowers rather than catkins) and handsome habit. Chinese Witch Hazel (Hamamelis mollis) was introduced to Britain in 1879. It flowers in Feb/March and has lovely autumn foliage. This was later crossed with the Japanese Witch Hazel (Hamamelis japonica) to produce Hamamelis x intermedia. This is now the most commonly grown of the Witch Hazels in the UK and has given rise to dozens of cultivars. It has larger flowers than its parents.

Note from webmother to  page visitors:
Many of these pages are still bare bones. Whenever time allows, we will continue to add information to the Tree Gallery until all the trees have descriptions of their habitat, characteristics, cultivation, uses and anything else of interest. Email us if you are keen to know more about a particular tree and we will do our best to complete that one next.
