 Shagbark Hickory
The Shagbark Hickory tree, Carya ovata, has a distinctive, shaggy
bark, conspicuous on tall straight trees, which gives this species
its name. It grows well in both wet and dry areas, but prefers
well-drained soils. Shellbark hickory trees are also called shagbark
hickory, bigleaf shagbark hickory, kingnut, big shellbark, bottom
shellbark, thick shellbark, and western shellbark, which attest to
some of its characteristics. It is a slow-growing long-lived tree.
The nuts, largest of all hickory nuts, are sweet and edible.
Wildlife and people harvest most of them; those remaining produce
seedling trees readily. The wood is hard, heavy, strong, and very
flexible, making it a favored wood for tool handles. The wood also
makes excellent firewood, and often is used in smoking meat. As with
other edible nuts, squirrels compete with humans for this fruit. Its
bold-textured, jagged branch structure and thick twigs give it a
striking appearance in winter. This deciduous shade tree has a
yellow fall color.

 Shellbark Hickory
The Shellbark Hickory tree, Carya laciniosa, is also know as
bigleaf shagbark, kingnut, big shellbark, bottom shellbark, thick
shellbark and western shellbark). This deciduous tree is similar to
that of the Shagbark Hickory, but often not quite as shaggy. The
fruit is larger than other hickories. This is a big tree and it
prefers wet, fertile bottomland. It is less common than either the
Shagbark or Bitternut Hickories. The wood is similar to that of the
Shagbark Hickory and is used in much the same way. Its sweet, huge
nuts are relished by squirrels and give it an alternative common
name of King Nut Hickory, due to their being the largest of the
hickories. Like other hickories, it is very tolerant of summer
drought. The nuts of shellbark hickory are utilized by wildlife
(ducks, quail, wild turkeys, squirrels, chipmunks, deer, foxes,
raccoons, and white-footed mice) and man. This tall shade tree
displays a yellow fall color.

 Pignut Hickory
The Pignut Hickory tree, Carya glabra, has medium green broad,
flat leaves and firm, gray bark. The bark may be marked in a sort of
diamond pattern by shallow furrows and narrow ridges. This tree
grows well in fairly rich, well drained to dry soils. It occurs with
other hickories and with oaks, characteristically on hillsides and
ridges. Pignut Hickory trees, as with other hickories, has wood that
is tough and strong. The nuts of this particular hickory, unlike
some of the others, are bitter and scarcely edible. The nuts they
are an important food for squirrels and chipmunks and other
wildlife. This shade tree turns a bright yellow for great fall
color.

 Bitternut Hickory
The Bittenut Hickory, Carya cordiformis, is also known as the
Yellow-bud Hickory tree. The yellow bud makes it difficult to
mistake for another species and combined with the alternate compound
leaves and relatively large nuts, it is very distinctive. The nuts
are reported to be bitter, as one of the common names suggests. The
lighter colored shallow cracks in the younger bark are roughly
similar to those of young Shagbark Hickory, but the mature bark of
Yellow-bud Hickory does not split so deeply. This deciduous tree is
found on moist, fertile soils in the east and central U. S. and is
intolerant of shade. Bitternut Hickory trees are known for their
hard wood. The wood is used for pulpwood and furniture. This
deciduous species displays a leaf color of medium green to dark
green. The fall color is often green to chartruese, but sometimes is
a brilliant golden-yellow in excellent seasons. It is a fast
growing, adaptable tree.
