Turkish Hazelnut (Corylus Colurna)

Turkish Hazelnut (Corylus colurna) is primarily grown as an ornamental specimen tree, valued for its striking columnar shape when young that broadens to a pyramid as it matures, elegant long catkins in spring, and attractive bronze-green autumn foliage. It is very hardy and tolerates most soil types including clay and chalk, making it one of the easier large trees to establish. The Turkish Hazelnut does produce edible nuts in clusters with frilly cups, and their flavour is genuinely good, similar to a common hazelnut. However, the nuts are smaller than commercial hazelnuts and have a notably thick, hard shell that makes them difficult to crack and extract. Crops are also inconsistent, producing every two to three years rather than annually. For these reasons, the Turkish Hazelnut is best chosen for its ornamental qualities, with the nuts treated as an occasional bonus rather than a reliable food crop. Can set some nuts without a pollinator, though yields improve with another hazelnut variety nearby.
