The Walnut Family (Juglandaceae)

Wood is in high demand by woodworkers for its rich, dark beauty. Certain plants will not grow under Black Walnut because of the chemicals produced by the roots of the tree. Preferred host for the Luna and Regal moths.

1.5 - 2.5” round nut covered by a fleshy, thick, light green husk.
Catkins (male tassel-like flowers) and small female flowers, both found near tip of stem, are yellowish-green and brown.
Squirrels eat the nuts, deer browse the buds, mice and rabbits nibble young tree stems and Eastern Screech Owls roost in the tree. Leaf length: 12.00-24.00 inches
Tree height: 70.00-100.00 feet XF60 32448 JM #39 B_ARBO Black Walnut.pdf
