Habitat :It is native to Europe and western Asia, from the British Isles south to Iberia, Greece, Turkey and Cyprus, north to central Scandinavia, and east to the central Ural Mountains, the Caucasus, and northwestern Iran.
Common hazel is typically a shrub reaching 3–8 m tall, but can reach 15 m. The leaves are deciduous, rounded, 6–12 cm long and across, softly hairy on both surfaces, and with a double-serrate margin. The flowers are produced very early in spring, before the leaves, and are monoecious with single-sex wind-pollinated catkins. Male catkins are pale yellow and 5–12 cm long, while female catkins are very small and largely concealed in the buds with only the bright red 1–3 mm long styles visible. The fruit is a nut, produced in clusters of one to five together, each nut held in a short leafy involucre (“husk”) which encloses about three quarters of the nut. The nut is roughly spherical to oval, 15–20 mm long and 12–20 mm broad (larger, up to 25 mm long, in some cultivated selections), yellow-brown with a pale scar at the base. The nut falls out of the involucre when ripe, about 7–8 months after pollination.
It is readily distinguished from the closely related Filbert (Corylus maxima) by the short involucre; in the Filbert the nut is fully enclosed by a beak-like involucre longer than the nut.
The leaves provide food for many animals, including Lepidoptera such as the case-bearer moth Coleophora anatipennella. Caterpillars of the concealer moth Alabonia geoffrella have been found feeding inside dead Common Hazel twigs. The fruit are possibly even more important animal food, both for invertebrates adapted to circumvent the shell (usually by ovipositing in the female flowers, which also gives protection to the offspring) and for vertebrates which manage to crack them open (such as squirrels and corvids).
The scientific name avellana derives from the town of Avella in Italy, and was selected by Linnaeus from Leonhart Fuchs’s De historia stirpium commentarii insignes (1542), where the species was described as “Avellana nux sylvestris” (“wild nut of Avella”).
Common Hazel is cultivated for its nuts. The name hazelnut applies to the nuts of any of the species of the genus Corylus. This hazelnut or cob nut, the kernel of the seed, is edible and used raw or roasted, or ground into a paste. The cob is round, compared with the longer filbert nut.
The hazelnut is the nut, of the hazel and is also known as the cobnut. It is roughly spherical to oval, about 15–25 mm long and 10–15 mm in diameter, with an outer fibrous husk surrounding a smooth shell. The nut falls out of the husk when ripe, about 7–8 months after pollination. The kernel of the seed is edible and used raw or roasted, or ground into a paste. The seed has a thin, dark brown skin which has a bitter flavour and is sometimes removed before cooking.
There are many cultivars of the Hazel, including ‘Barcelona’, ‘Butler’, ‘Casina’, ‘Clark’ ‘Cosford’, ‘Daviana’, ‘Delle Langhe’, ‘England’, ‘Ennis’, Fillbert, ‘Halls Giant’, ‘Jemtegaard’, ‘Kent Cob’, ‘Lewis’, ‘Tokolyi’, ‘Tonda Gentile’, ‘Tonda di Giffoni’, ‘Tonda Romana’, ‘Wanliss Pride’, and ‘Willamette’. Some of these are grown for specific qualities of the nut including large nut size, and early and late fruiting cultivars, whereas other are grown as pollinators. The majority of commercial Hazelnuts are propagated from root sprouts. Some cultivars are of hybrid origin between Common Hazel and Filbert.

Common Hazel is cultivated for its nuts in commercial orchards in Europe, Turkey, Iran and Caucasus. The name “hazelnut” applies to the nuts of any of the species of the genus Corylus. This hazelnut or cobnut, the kernel of the seed, is edible and used raw or roasted, or ground into a paste. The seed has a thin, dark brown skin which has a bitter flavour and is sometimes removed before cooking. The top producer of hazelnuts, by a large margin, is Turkey, specifically the [[ORDU Province]. Turkish hazelnut production of 625,000 tonnes accounts for approximately 75% of worldwide production.
The Common Hazel is a shrub common in many European woodlands. It is an important component of the hedgerows that were the traditional field boundaries in lowland England. The wood was traditionally grown as coppice, the poles cut being used for wattle-and-daub building and agricultural fencing.
Hazelnuts are rich in protein and unsaturated fat. Moreover, they contain significant amounts of thiamine and vitamin B6, as well as smaller amounts of other B vitamins. Additionally, 1 cup (237 ml) of hazelnut flour has 20 g of carbohydrates, 12 g of which are fibre.
Hazelnut oil is a good carrier oil in aromatherapy applications, it has a slightly astringent action that is good for all skin types. The name “hazelnut” applies to the nuts of any of the species of the genus Corylus. This hazelnut or cobnut, the kernel of the seed, is edible and used raw or roasted, or ground into a paste. Hazelnuts are extensively used in confectionery, hazelnut butter is being promoted as a more nutritious spread than its peanut butter counterpart, though it has a higher fat content.
Yellow color contains vitamins, minerals, protein slightly astringent, good for all skin types. Absorbed quickly into the skin, it has tonifying and astringent action. Good for those with slightly oily skins, dry, devitalized, or sun damaged. A lovely carrier oil for aromatherapy skin care blends.
They are under the dominion of Mercury. The parted kernels made into an electuary, or the milk drawn from the kernels with mead or honeyed water, is very good to help an old cough; and being parched, and a little pepper put to them and drank, digests the distillations of rheum from the head. The dried husks and shells, to the weight of two drams, taken in red wine, stays lasks and women’s courses, and so doth the red skin that covers the kernels, which is more effectual to stay women’s courses.
