Introduced from native central and eastern America into Europe in 1629, this fast growing tree won the Award of Garden Merit in 2002.
The national US champion stands at 44 metres high by 47 metres wide in Oregon so not one to be planted in restricted places.
It makes a large tree with a broadly pyramidal crown and is a very good choice for parkland settings.
It produces an abundance of nuts over a long period, but they are rather difficult to extract from their very hard shells.
Rough barked from a young age so easily distinguished from the smooth barked Juglans regia.
It grows on most soils but thrives on deep loam.
Mature height: 20m+
Mature spread: 15-20
