Walnut trees, no matter their name, are prized for both the nuts they produce and their wood, valued highly for furniture, cabinets and flooring. While all have the same basic needs, the different varieties grow at different rates.
Three main types of walnut trees grow in the United States: English walnut, black walnut and butternut, which is sometimes called white walnut.
Fast growth (25 inches or more per year) is one of the traits of the English walnut tree. These trees are hardy in zones 5 to 9 and produce a thin-hulled nut that is easily cracked.
Black walnut trees, hardy in zones 4 to 9, are moderate growth rate trees. Annual growth rates will be between 13 and 24 inches per year.
Butternut trees, or white walnuts, grow at a rate of 12 inches or less per year, making them a slow growth tree. They are hardy in USDA zones 3 to 7.
All three varieties of walnut tree are nut bearers with highly edible and prized nuts, which can be eaten raw or cooked.
