Summary

Corylus species The hazel is a genus of deciduous shrubby trees and large shrubs native to the temperate Northern Hemisphere. Some Corylus species can tolerate Mediterranean climates without sufficient water and are not well-suited to arid or semi-arid climates. Worth considering is Beaked Hazel (C. cornuta), whose native range is Canada to the U.S.A., including California, Colorado, Idaho, Montana, Wyoming, and Washington. Turkish Hazel (C. colurna) native range from SE. Europe to N. Iran. Including Greece, Iran, North Caucasus, Romania, Transcaucasus, and Turkey and has been introduced to Spain. European or Common Hazelnut (C. avellana) native range is Europe to the Caucasus, including Corsica, Greece, Italy, Portugal, Sardinia, Sicily, Spain and Turkey. It has sweet nuts with a thin shell. Suitable cultivars are ‘Cosford’, ‘Pearson’s Prolific’ and ‘Red Majestic’. The sweet nuts of all hazels, cultivated for centuries, are edible and will make a tasty addition to any food forest. Often grown as a coppiced shrub in woodlands, regenerating shoots allow for stem harvests every few years. Coppicing is a traditional woodland management method where stems are repeatedly cut down near the ground, creating a timber self-renewing source. Make wattle fencing, thatching spars, walking sticks, fishing rods, basketry, and pea and bean sticks from the new growth. Most tree species will coppice, but hazel, sweet chestnut, ash and lime are more suited. Coppicing hazel prevents over-shading, allowing ground layer plants to thrive and creating dense wildlife habitats. Hazel coppice cycles are 7-10 years. The flat, suckering root pattern forms a plate near the soil surface. Sweet nuts are excellent raw or roasted for bread, cakes, biscuits, pies, and sweets. Liquidized with water, they make tasty plant milk. Extracted hazelnut oil is used for salad dressings and cooking. If unshelled, the nuts keep for at least 12 months. Fertile soils can lead to excessive growth and inferior crop sizes. Planting two or more cultivars and growing in groups produces better pollination. Larger nuts are grown on old wood. Form: Oval, Pyramidal.

Edible Uses

Edible Parts: Oil  Seed
Edible Uses: Oil

Seed - raw or cooked[2, 22, 46, 105]. Rich in oil. As nice a flavour as C. avellana, the common hazel nut[146, 158]. The seed ripens in mid to late autumn and will probably need to be protected from squirrels[K]. When kept in a cool place, and not shelled, the seed should store for at least 12 months[K]. An edible oil is obtained from the seed.

Other Uses

Oil  Wood

Hazels can be used in agroforestry systems as a hedge, windbreak, or for erosion control. They can also be intercropped with other plants, benefiting soil health and biodiversity. Wood - firm, durable, moderately hard. Used for furniture, turnery etc[74, 158]. 1. Nectary - Flowers rich in nectar and pollen: No – Hazels produce wind-pollinated catkins, which are not rich in nectar but produce pollen that some insects may utilize. 2. Wildlife - Food (Fruit, Seeds, Leaf litter, Shelter, Nesting, Roosting): Yes – The nuts (hazelnuts) are a valuable food source for birds, small mammals, and insects. Hazels also provide dense foliage for shelter and nesting, while leaf litter supports a variety of organisms. 3. Invertebrate Shelter (Overwintering sites, Leaf litter, Groundcover): Yes – Hazels provide excellent overwintering sites in their rough bark and dense foliage. The leaf litter supports invertebrates and provides shelter at ground level. 4. Pest Confuser (Smell): No – Hazels do not have a strong scent that would confuse or repel pests.

Cultivation details

Management: Standard  Regional Crop  Staple Crop: Protein-oil

Landscape Uses:Firewood, Specimen, Street tree. An easily grown plant, it succeeds in most soils, but is in general more productive of seeds when grown on soils of moderate fertility[11, 200]. It does less well in rich heavy soils or poor ones[11, 63]. Does well in a loamy soil[11]. Very suitable for an alkaline soil[11], but it dislikes very acid soils[17]. Tolerates a pH in the range 5.3 to 7.3. Once established, this is a very drought resistant tree[183]. It does not produce suckers[183]. Plants are fairly wind tolerant[1, 11]. A very ornamental tree[1]. Members of this genus bear transplanting well and can be easily moved even when relatively large[11]. The Turkish hazel is occasionally cultivated for its edible seed[46, 61, 158]. This species is also useful in hybridizing with C. avellana in order to develop superior fruiting cultivars[183]. Special Features:Not North American native, Inconspicuous flowers or blooms. The plant is heat tolerant in zones 7 through 5. (Plant Hardiness Zones show how well plants withstand cold winter temperatures. Plant Heat Zones show when plants would start suffering from the heat. The Plant Heat Zone map is based on the number of "heat days" experienced in a given area where the temperature climbs to over 86 degrees F (30°C). At this temperature, many plants begin to suffer physiological damage. Heat Zones range from 1 (no heat days) to 12 (210 or more heat days). For example Heat Zone. 11-1 indicates that the plant is heat tolerant in zones 11 through 1.) For polyculture design as well as the above-ground architecture (form - tree, shrub etc. and size shown above) information on the habit and root pattern is also useful and given here if available. The plant growth habit is a standard with a non-suckering single trunk [1-2]. The root pattern is flat with shallow roots forming a plate near the soil surface [1-2]. Corylus species are considered medium to fast-growing, reaching a height of about 3 to 6 meters (10 to 20 feet) within 5 to 10 years, depending on the specific variety and growing conditions. Hazelnuts are typically harvested in late summer to early autumn, when the nuts have matured and fallen from the trees. Hazels flower in late winter to early spring, with male catkins producing pollen before the female flowers emerge. Most Corylus species are not self-fertile and require cross-pollination from another variety to produce nuts. Corylus colurna is self-fertile.

Carbon Farming

  • Management: Standard  Plants grow to their standard height. Harvest fruit, seeds, or other products. Non-Destructive management systems.
  • Regional Crop  These crops have been domesticated and cultivated regionally but have not been adopted elsewhere and are typically not traded globally, Examples in this broad category include perennial cottons and many nuts and staple fruits.
  • Staple Crop: Protein-oil  (16+ percent protein, 16+ percent oil). Annuals include soybeans, peanuts, sunflower seeds. Perennials include seeds, beans, nuts, and fruits such as almond, Brazil nut, pistachio, walnut, hazel, and safou.

Plant Propagation

Seed - best sown as soon as it is harvested in autumn in a cold frame[164]. Germinates in late winter or spring. Stored seed should be pre-soaked in warm water for 48 hours and then given 2 weeks warm followed by 3 - 4 months cold stratification[164]. Germinates in 1 - 6 months at 20°c[164]. When large enough to handle, prick the seedlings out into individual pots and grow them on in a cold frame or sheltered place outdoors for their first winter. Plant them out into their permanent positions in late spring or early summer[K]. Layering in autumn. Easy, it takes about 6 months[78, 200].

Mr Nixon   Tue May 30 2006

very helpfull thankyou, i needed some of this information for my course work. in my opinion it is clear and easy to read, but the only thing bad i will say is that you should put significant pests and diseases of this tree on there and you should have the basic maintenance of the tree when it is young, and a few pictures wouldnt go amiss either.

Dr K.K. Srivastava, Assistant Professor, SKUAST -k, Shalimar, Srinagar, J& K    Wed Nov 15 2006

In kashmir condition Corylus colurna is found in ample amount, i have tried its propagation by sucker cutting in IBA treatment and incourgaging success have been attained. Further its sucker grown on the root hence it is difficult to raise from since it has no fibrous root. A part of previous wood helps for rooting .

i need seeds of this tree if possible can be plant in western african country or more trees are have shade please email me to let me know how to reach you or how to get those seeds thank you
