Summary

Corylus colurna, commonly known as Turkish Hazel, is a deciduous tree native to Southeastern Europe, Western Asia, and parts of the Middle East. It thrives in a variety of woodland settings, often on well-drained soils in hills and mountainous regions. This species can reach heights of 40-80 feet with a width of 30-50 feet, and it features a dense, pyramidal to oval form. The Turkish Hazel blooms in early spring, producing separate male and female flowers on the same tree; the male catkins are yellow and pendulous, while the female flowers are small and red. The tree is particularly noted for its corky bark and showy, fringed husks that encase the edible nuts.

Turkish Hazel is valued for its hardiness in urban environments, where it can withstand pollution and soil compaction, and its symmetrical crown is appreciated for formal landscape designs. It is used for avenue planting, as a specimen tree, and in large gardens. While it can tolerate a range of soil conditions, including occasional drought and alkaline soils, it prefers moist, well-drained sites and full sun to part shade. Once established, it is also tolerant of heat and cold. Corylus colurna is relatively free of serious pests and diseases, but its deep root system can make transplanting difficult. It requires additional watering during the first couple of years after planting until it becomes fully established.CC BY-SA 4.0
