Black Walnut
(Juglans nigra)
NAME:
COMMON – Black Walnut
BOTANICAL – Juglans nigra
FAMILY – Juglandaceae
DERIVATION:
Native to a broad swath of central and eastern North America
GROWTH CHARACTERISTICS:
This massive tree can grow to 50 to 90 feet high with a 3 to 6 foot diameter trunk when mature. It has the habit of losing its lower branches to begin its spread at 20 feet above the ground.
LOCATION:
It grows well on rich bottom lands, in moist, fertile coves and on lower slopes throughout North Carolina. The black walnut works well as a shade tree in meadow and woodland locations.
ATTRIBUTES, VALUE, UNIQUE CHARACTERISTICS:
The nuts are edible but difficult to remove from the husk, and the fleshy husk can be used to make a brown dye. Once used by Native Americans medicinally, the tree is a scarce, valuable native hardwood used for furniture and veneer. It also can be used in butterfly, edible, native and nighttime gardens.
