 (Juglans nigra Northern) Deciduous. Zones 4-7.

Black Walnut is a monumental shade tree with a long, sturdy trunk and open, oval crown that can reach up to 100 feet. It was once prized for its nuts, which have a long history in medicinal use and are some of the most versatile nuts in the world. Its wood is so coveted that it has sadly been over harvested in the wild.

Black Walnut is a traditional food of Indigenous People. Nuts are delicious and the sap can be boiled down for syrup. The walnuts can be used to dye cloth a dark purple colour. 

 A beautiful tree, Black Walnut has dark grey, deep ridged, diamond patterned bark and a high, generous canopy. Its light green leaves are made up of multiple spear-shaped leaflets. It needs a lot of space to grow and should not be planted close to other plants. 

The nuts mature in Fall, falling to the ground where the yellow-green husks turn black as they rot. The kernels inside are a bit hard to get to, but offer a sweet, oily delicacy high in omega-3s! Try them in soups, roasted and sprinkled on salads, and baked into casseroles to lend rich flavour to your cooking.

 Black Walnut wood is dense, strong, and has a gorgeous deep brown colour and interesting grain. It is one of the best woods available from any native tree in North America for furniture making and shipbuilding. 

** Please note that all members of the Juglans family (Butternuts, walnuts, heartnuts, etc.) create a protective substance in their roots called Juglone. This can kill certain other plant species within the root zone.
