Juglans  nigra  L. Black walnut   - Juglandaceae

Indigenous to eastern United States this tree, Juglans nigra, is valued for its wood and oily nuts which are a prized ingredient in confections.  Leathery spherical fruits 2-3 inches (5-7 cm) in diameter encase oval, slightly flat, dark brown nuts which are deeply divided into irregular ridges. In colonial America women soon learned that the nut's husks proved a permanent and beautiful dye for their woolens.

In Hawaii, black walnuts are strung into leis. Elsewhere slices of the nut's shell are used ornamentally in belts and pendants.
