wide ranging. The needles emit a pleasant odor when crushed. |
|
3) Black Cherry—Prunus serotina
Cherry is one of the more valuable American trees, and is
a favorite for fine furniture and cabinet work. However, the
trees can pose a problem to the unwary farmer because the
twigs and leaves contain enough cyanide to kill livestock. |
|
3a) Chinquapin Oak—Quercus muehlenbergii
Chinquapin oak is also known as the “disguised” oak.
Its leaves resemble those of chestnut and are commonly misidentified.
The wood provides strong and attractive lumber. This tree is located
north of State Street in Duhme Woods, just south of Duhme Hall. |

zone landscapes of the U.S. and Europe. |
|
5) Sycamore—Platanus occidentalis
The white, stark branches of sycamore haunt the creek banks and bottomlands
of the eastern U.S. Rapid growth makes the sycamore popular for
ornamental and pulpwood uses. This “space tree,” which
germinated in outer space, was planted in spring 1990 by astronaut
Jerry Ross and his wife Karen (NASA food expert) to commemorate
the impact 4-H experiences had on their lives. |
| |
6) Allee Elm—Ulmus parvifolia ‘EmerII’
Allee elm is one of several varieties of lacebark elm gaining
widespread acceptance as a tree well suited for urban
conditions. It has a vase shape similar to American elm
with an exfoliating bark that that creates a beautiful mosaic
of orange, tan, and gray on mature trees. This tree is
resistant to Dutch elm disease and phloem necrosis. |
| |
7) Amur Corktree—Phellodendron amurense
The corktree has large branches that grow in a picturesque manner.

is not used in cork production. The inner bark is a brilliant yellow
color. |
|
8) Black Gum—Nyssa sylvatica
This is a tree with eye-catching features throughout much of the
year. It has a neat, pyramidal form that shows well in all seasons.

and scarlet in the fall. The alligator hide-like bark is another
striking characteristic. |

shade and ornamental tree with a pleasing form and brilliant fall
colors. |

conditions. It grows to a height of 50 to 60 feet
in the landscape. The leaves often turn a bright yellow color in
the fall. |
| |
11) Columnar Sargent Cherry—Prunus sargentii

flowers open in late April. The glossy, reddish-brown bark is another
attractive feature. |
| |

Douglas fir is the most important timber species in the U.S. Ranging
throughout the western Rocky Mountains and the Pacific Northwest,
it is used to produce lumber, plywood, and pulp. |
| |
13) Paperbark Maple—Acer griseum
As the name suggests, this tree’s most outstanding feature
is its bark. Much like a birch’s, the bark of this tree peels
back in paper-thin sheets to show a beautiful cinnamon
color. This maple is an import from China and, like most
maples from Asia, remains relatively small, growing to 25
feet in height. |
| |
14) Crimson Spire Oak—Quercus alba x robur ‘Crimschmidt’

fall color of white oak with the narrow growth habit of
columnar English oak. It can grow to a height of 45 feet
with a crown spread of only 15 feet. |
| |
15) White Fir—Abies concolor
This tree is notable for its blue-green needles that curve upward.
It can grow up to 50 feet tall and 15 to 30 feet wide. White fir
is similar to Colorado blue spruce but presents a softer appearance,
which is helping it gain acceptance as
an alternative in landscaping. |
| |
16) Blue Ash—Fraxinus quadrangulata
Native to the United States, this ash can be identified by its
square twigs and scaly bark. When exposed, the inner bark
turns a shade of blue. This was used by early pioneers to
dye cloth. |
| |
17) Pawpaw—Asimina triloba
Due to the taste and texture of its fruit this tree has been
called the ‘Indiana banana’. In the open, pawpaw will grow
to about 20 feet tall with a pyramidal shape. It has the
distinction of growing the largest tree fruit of any tree native
to the United States. |
| |
18) Japanese Pagoda Tree—Sophora japonica
This is one of the few trees to flower in August, when it develops
large clusters of white blossoms. The common name for this tree
comes from its frequent use around Buddhist temples in Asia. |

It is a rarely planted conifer with “weeping” branches
and blue-gray needles. |
|
20) Sugar Maple—Acer saccharum
Sugar maple, named for its sweet sap, provides much more than maple
syrup. These trees can be found in many yards and parks, where
their graceful form and shade are appreciated. Children also enjoy
playing with the familiar “helicopter seeds.” Sugar
maple is the state tree of New York, Vermont, and Wisconsin. |
| |

A small tree or large shrub whose small white flowers emerge with
leaves in the spring and develop into interesting four-winged fruits. |
|
26) Black Walnut—Juglans nigra
Walnut is the single most valuable tree species in the U.S. Nut crops
from walnuts mature in the fall. Many people gather the tasty nuts,
despite the brown stain caused by the outer hull. Black walnut
occupies the richest creek bottoms. |
| |
27) Shumard Oak—Quercus shumardii
Shumard oak grows predominantly in the southeastern U.S. Although closely related
to red oak, the wood from this tree is said to be stronger than that of red
