The European hazelnut (Corylus avellana), also known as the common hazel, is a deciduous, multi-stemmed tree or shrub prized for its delicious nuts, ornamental appeal, and wildlife value. Native to Europe and parts of Asia, it is a cold-hardy and adaptable tree that thrives in temperate climates, making it a great addition to home gardens, orchards, and agroforestry systems.
