Juglans nigra

black walnut

Black walnut is a great shade tree that produces tasty nuts in the fall. The pinnately-lobed leaves are strongly aromatic when crushed. It is well known for being allelopathic, however, other native plants are rarely affected by the chemical inhibitors released by black walnut.
