Turkish Hazel tree identification

The Turkish Hazel Corylus colurna, native to South-East Europe, Turkey and Iran was was introduced to Britain in 1582. It is an attractive tree, with a straight trunk. It is the largest species of Hazel and can reach a height of 20m.  It has been widely planted in city streets, where it thrives. It is tolerant of urban air pollution.  Its buds, catkins and nuts are similar to the Common Hazel but its fruit looks quite different because the nut sits in a cup that has long prickles. The nut is edible but it is hard and small and of no commercial value. For more information on the Common Hazel click HERE
