Walnut  black

            The walnut tree produces a substance called juglane which is allelopathic to other plants, i.e. it is poisonous to them and thus it is said that nothing grows under a black walnut tree.

          The nuts of the black walnut are edible, but alas they are not the ones that you find in the shops and which are used for confectionery; those nuts come from the Persian walnut tree, of which there are examples in Lincoln's Inn.

            The leaves are arranged pinnately compound (see tree identification section) and are quite large.

            The tree which produces the nuts that are eaten around Christmas time originates from Iran and this one comes from not far away from there: Turkey.

The more familiar sight
of the nuts without their skin.
