Cultivated for many centuries and growing into a substantial tree of about 8-12 m in height. The almost round crown is composed of heavy branches. The old trunk is light grey with deep, irregular vertical grooves. The odd-pinnate leaves grow to 20 - 30 cm long and have 2 - 4 (6) yokes. The partial leaves are ovate to oval, about 8 - 12 cm. After leaf development, the green, male catkins (circa 7 cm) and the smaller female flowers appear, arranged in groups of 2 or 3 together. The green, almost round, fruit has a smooth husk that is initially still short, glandularly hairy. The light brown nut is grooved. Particularly tasty. Nuts do not appear until around 15 years old. Roots very deeply and prefers well-rooted, open soil. Important timber producer.
