Juglans nigra
black walnut
The black walnut is a great shade tree that produces tasty nuts in the fall. The pinnately-lobed leaves are strongly aromatic when crushed. Black walnut is allelopathic, releasing chemicals from its roots that inhibit the growth of other plants, with some exceptions... ask us for a list of resistant species!
