Common Walnut Juglans regia

Other Common Name(s):

Description

English Walnut is a deciduous tree native to Europe and Asia that is widely cultivated for the sweet nuts. It grows 40-60 feet tall and wide with a rounded spreading crown.  It will generally produce a good crop of fruit in about 15-20 years. 

Grow in humusy moist well-drained soils in full sun as a shade tree and for the fruits. It is difficult to transplant due to a deep taproot. This tree doesn't do well in hot humid climates and the pecan tree is a better choice.
