What is a Walnut Tree?
Walnut trees are deciduous trees native to North America, Europe, and Asia.
They are part of the Juglandaceae family, which includes hickories and pecans.
Walnut trees can grow up to 100 feet tall, with a spread of up to 60 feet.
The trees have a thick, furrowed bark and large, compound leaves, which are divided into five to nine leaflets.
The nuts are encased in a thick, green outer husk, which splits open when the nut is ripe.
The nut itself has a hard, brown shell and a creamy, edible kernel.
Walnut trees produce fruit from late summer to early fall and are a valuable source of food for wildlife.
