“Corylus colurna (Turkish Hazel) is a large imposing tree, columnar when young before broadening to a symmetrical pyramid on maturity. Notable for its roughly textured, corky bark, it produces long, yellow catkins in early spring and clusters of fringed nuts in autumn. Corylus colurna is a superb choice for parkland and avenue planting, and it will tolerate paved areas. It thrives in all soils, including chalky and clay soils and is used in cities as a substitute for Lime to combat the problem of aphid drop on cars and pavements.”
