Summary

Corylus x colurnoides, a hybrid of Corylus avellana and Turkish hazel. It has a shrubby habit, but sometimes becomes a tree up to 20m. The bark tends to be less corky, more fissured and only somewhat peeling on young plants compared to either of the parents. The hybrid is noted for its fine-tasting nuts.


Physical Characteristics

 icon of manicon of lolypop
Corylus x colurnoides is a deciduous Tree growing to 15 m (49ft) by 15 m (49ft). It is in flower from April to May. The species is monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) and is pollinated by Wind.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils and can grow in very alkaline soils.
It can grow in semi-shade (light woodland) or no shade. It prefers moist soil. The plant can tolerates strong winds but not maritime exposure.

Edible Uses

Edible Parts: Oil  Seed
Edible Uses: Oil

Seed - raw or cooked[183]. Very tasty[177]. The seed makes an excellent dessert nut, tasting just like the cob and filbert[183, K]. It can also be dried and ground into a powder then used in making nut milks, bread etc[183]. 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.

Now available: PLANTS FOR YOUR FOOD FOREST: 500 Plants for Temperate Food Forests and Permaculture Gardens.

An important new book from PFAF. It focuses on the attributes of plants suitable for food forests, what each can contribute to a food forest ecosystem, including carbon sequestration, and the kinds of foods they yield. The book suggests that community and small-scale food forests can provide a real alternative to intensive industrialised agriculture, and help to combat the many inter-related environmental crises that threaten the very future of life on Earth.

Cultivation details

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]. Plants are fairly wind tolerant[1, 11]. A hybrid of garden origin, it combines the non-suckering, winter hardiness and vigorous growth of C. colurna with the free-falling, early bearing and large nut size of C. avellana[183]. There are some named varieties, selected for their edible seeds[183, 200]. Members of this genus bear transplanting well and can be easily moved even when relatively large[11]. 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].

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]. This species is a hybrid and will not breed true from seed. Layering in autumn. Easy, it takes about 6 months[78, 200].

Steve Joul   Sun Oct 12 2008

Britain's Champion Corylus x colurnoides, planted by Edward Oates at Meanwoodside, Green Road, Leeds (Grid ref. SE 28135 37277) after he bought the estate in 1834, purchased from Loddiges Nursery who first made it available in 1836 after it was identified there by the great J.C. Loudon who included it in his standard tree reference. It was lost to science, outliving all who knew of it, and predates the only other well known tree at Kew by 100 years. It was rediscovered in Germany by Schneider after which Kew obtained a good specimen and young trees are now widely planted. Now towards the end of it's life, the original is still a wonderful tree with 2 trunks grafted onto a Turkish Hazel stock. Easily seen in the public park.
