Common Hazel
Created by admin

The common hazel (Corylus avellana) is a deciduous woody plant native to Europe, Asia and North Africa. In many English-speaking countries it is referred to as the hazelnut. It is the principal species of the genus Corylus. The common hazel is a large tree growing to 20 m (66 ft) tall, with stout stems clad in smooth, brownish bark. The leaves are deciduous, rounded, 6–12 cm (2.4–4.7 in) long and across, softly hairy on both surfaces, and with a double-serrate margin. The flowers are produced early in spring on catkins 2–5 cm (0.79–1.97 in) long, the individual flowers pendulous, with no petals, and wind-pollinated.

Hazelnuts prefer well-drained soils with a pH in the range of 5.5 to 8.0. They also prefer a soil rich in organic matter. The optimum growing temperature for hazelnuts is between 15 and 20 °C (59 and 68 °F). In commercial hazelnut production, trees are generally spaced 4 m (13 ft) apart in the row. It is wind pollinated.

other uses:
Hazelwood is sometimes used in jewelry, particularly rosaries. It is also used in woodworking, turned objects, and musical instruments such as guitars and marimbas. Hazelnuts are used in the production of hazelnut oil, a strongly flavored oil used as a cooking oil and in cosmetic formulations. Hazelnut shells are sometimes used as an abrasive for cleaning metal objects.

potential disturbances:
The common hazel is susceptible to a number of fungal diseases. These include brown rust (Pucciniastrum coryli), powdery mildew (Erysiphe coryli), scab (Venturia inaequalis), and Verticillium wilt (Verticillium albo-atrum). Hazelnuts are also susceptible to the Eastern Filbert Blight (Anisogramma anomala), a disease that has destroyed many hazelnut trees in North America. The common hazel is used as a food plant by the larvae of a number of Lepidoptera species; see List of Lepidoptera that feed on hazels.
