Identification Clues:
The most conspicuous characteristic of this
deciduous, slow growing tree is the pinnately compound leaf. One
leaf is composed of many leaflet pairs that arise along a long central
axis. The flowers are a cluster of drooping catkins. The branches
arise alternately from the trunk. The fruit of the tree is a nut,
each containing one seed.
Distribution:
The Black walnut is one of the most valuable
native trees. It is found throughout the eastern part of the country,
and in South Dakota is native along the Big Sioux River.
Highlights:
The beauty and durability of the heartwood
of the Black walnut makes it highly prized by carpenters. Other uses
of its products include its bark for tanning, nut husks for dye, and the
nut for food. |
