Because the walnut and hickory trees are so common in the United
States and many of them are so well known to millions of Americans, they are grouped and
described as one big family.
An offshoot hybrid of the family is the pecan which is really a version of the hickory
nut.. The pecan resembles the hickory nut shell with lengthwise lines.
By breeding the nut shell has been hybrid to round and oblong shapes, thick and thin
shells, and different moist and dry nutmeats. The walnut
has 15 different known varieties scattered from the Mediterranean to Eastern Asia, from
Indo-China to the Andes and then to the North and South American continents.

Kingnut Hickory
Shellbark Hickory
The Kingnut Hickory is found in moist bottom land soils along the
upper Mississippi and Ohio Rivers. The tree reaches 100 feet and the bark is
shaggy, but less shaggy thatn the Shagbark Hickory.
The nuts have an outer husk. Like a chestnut, they are dried and then split open to
reveal the true interior nutmeat. The shell of the nut is hard and
brittle.. There are ridges running from the top to bottom of the nut.
The nut is about 1-2" long. The kernel can be broken in half like a
walnut. The nut is corrugated and convoluted like a walnut, but flatter and
drier. Squirrels love them but humans prefer hybrid walnuts which taste better.
Mocknut Hickory
Bullnut Hickory
White Hickory
The tree grows to 100 feet. The trunk can grow to 3' in
diameter. It grows in the eastern United Srtates, the Atlantic seaboard, pine
forests of the coastal plains, and along the Gulf of Mexico.
The nut is 1-1/2" long and very thick shelled even for a hickory nut. There are
four ribs on the husk and the kernel is small and sweet. The tree was probably
the first tree noticed by the European colonists as they roamed the eastern
seaboard. The name "mockernut" is thought to be a corruption
of the Dutch word "mokker", a kind of heavy hammer referring to the force
required to break the heavy, hard shell.
Pignut
Redheart Hickory
The Pignut grows throughout the southern United
states. The tree is usually 80 feet tall. The nuts are small, about
1-1/4" long. They lack ridges and the small kernel can be sweet, but usually is
bitter tasting.. The outer husk is quite thin and often splits when mature along its
length.
Because of the bitter taste, the Pignut is one of a number of hickory nuts that are not
used as edible food for humans..
