The fruits are ready for harvesting by the autumn, when the thick green hull begins to crack open to expose the hard-shelled walnut that has a light brown color. Each nut features roughly spherical in shape and weights about 15 g and has a single edible kernel inside.
The walnut kernel has two uneven, corrugated lobes, off white in color and covered by a thin, light brown skin. The lobes are partially attached to each other. Oil extracted from the nuts is used in medicine, and aromatherapy (apart from cooking).
