More Information

The Walnut Butternut tree is one of the hardiest of the nut tree family. Native to North America, the tree is medium sized at approximately 40-80 feet with a 35-50 foot spread. It is a slow grower averaging about 12 additional inches each year.

The leaves of the tree are pinnately compound with 7-17 leaflets arranged alternately on the stem. The leaves are typically 10-20 inches long and medium green in color. They will turn yellow in the fall.

The tree flowers in late spring. The male flowers are slender, yellow-green catkins and the females are short, terminal spikes. In September and October, the sticky nuts mature inside oblong green shells. Nuts are found singly or in clusters of two to five.

The seed of the nut is edible, with a buttery flavor. Nut hulls remain on the tree through autumn. A tree will not yield nuts until seven to ten years after being planted.

The Walnut Butternut tree grows best in rich, moist, deep soil that is acidic or alkaline, and loamy, sandy or clay. Hardiness Zone: 3-7.
