Summary

Juglans regia, commonly known as English Walnut, is a deciduous tree originally from a range of habitats including the mountainous forests of Western and Central Asia, as well as the Middle East. It can grow to heights of 25–35 m (80 to 120 ft) with a trunk up to 2 m (6 ft) in diameter. Typically, it has a short trunk and broad crown, but it can grow taller and narrower when in competition for light in dense forests. The bark is smooth and olive-brown on young trees, becoming silvery-grey with age and developing broad fissures. English Walnut is notable for its male flowers, which are drooping catkins 5–10 cm (2 to 4 in) long, and its female flowers that appear in clusters, maturing into fruits with a green, semifleshy husk and a corrugated nut in autumn. The nuts are known for their rich flavor and relatively thin shells.

The English Walnut is valued for its edible nuts and is often cultivated in orchards for commercial nut production. It is also planted as a shade tree in parks and large gardens. The tree’s ability to produce juglone, a natural herbicide, can be both a benefit and a drawback, as it can prevent the growth of other plants underneath its canopy. This species requires full sun and long summers, thriving in rich, deep soils with good drainage. While it prefers high amounts of water, it is also relatively drought-tolerant once established. Gardeners should be aware that English Walnut can be invasive in some regions outside its native range, and its cultivation should be carefully considered.CC BY-SA 4.0
