Is Corylus avellana contorta edible?
The name ‘hazelnut’ applies to the nuts of any species in the genus Corylus, but in commercial contexts usually describes C. This hazelnut or cob nut, the kernel of the seed, is edible and used raw, roasted, or ground into a paste. It is famous along with other species of the genus Corylus for its production of hazelnuts (cobnuts) though avellana is the most commonly used for production. It enjoys full sun conditions and produces suckers that may need to be pruned.
Is Corylus avellana self-pollinating?
Hazel flowers must be pollinated by pollen from other hazel trees. Leaves are round to oval in shape, and pointed at the tip. Hazel grows in woodland, scrub and hedgerows. It can reach up to 12m in height. Hazel can live to about 70 or 80 years of age – coppicing, however, can dramatically increase its lifespan. Coppicing allows the shrub to constantly renew itself. The ‘stool’ (the base of the plant that remains uncut) is the only part of the plant that reaches any great age.Corylus avellana has a moderate growth rate, growing around 40-60cm a year. Many hazel trees will take more than 10 years to reach their eventual height. Although it can grow to 12m tall in the wild, it’s easy to keep a hazel tree compact by pruning regularly.
