Corylus colurna (Turkish Filbert)
Turkish filbert is a native of southeastern Europe. The tree
grows to approximately 40 feet in height, with a pyramidal
form. It is known for its ability to withstand drought and
Quercus rubra (Red Oak)
Red oak is the most commercially important oak. It is a
desired timber and ornamental species and can be easily
transplanted. Fine furniture and veneer are manufactured
from red oak. This particular red oak was originally in
the way of the construction of Armstrong Hall. When this
was pointed out, the building was redesigned in order to
preserve the tree.
Acer griseum (Paperbark Maple)
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.
Sassafras albidum (Common Sassafras)
Best known for the tea made from its roots, this first forest
export from the 'new world' also produced a popular red
dye. After forest disturbance, the seeds and root suckers of
the sassafras tree sprout aggressively.
Koelreuteria paniculata (Goldenraintree)
The outstanding feature of the golden-rain tree is its showy
clusters of bright yellow flowers that bloom in late June
or early July. The tree’s large seed pods turn an attractive
bronze color in the fall.
Ulmus pumila (Siberian Elm)
Commonly called Chinese elm, this tree is often planted
for its shade because of its rapid growth rate, but this
species of elm is weak-wooded and has continuous dieback
problems once it reaches a large size. This characteristic
makes Siberian elm undesirable for landscaping purposes.
Gymnocladus dioicus (Kentucky Coffeetree)
The coffeetree bears stout twigs and large, feathery,
compound leaves up to three feet long. Locally scarce, the
tree is used for ornamental purposes. Pioneers roasted the
seeds for imitation coffee.
Quercus alba (White Oak)
White oak is an important hardwood timber tree and the
best cooperage wood in the U.S., used in the construction
of buckets, pails, and barrels. This tree produces acorns
that are eaten by many species of wildlife. It is the state tree
of Maryland and Illinois.
Nyssa sylvatica (Black Gum)
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. The leaves are a dark, glossy green in the
summer and turn to orange and scarlet in the fall. The
alligator hide-like bark is another striking characteristic.
Quercus phellos (Willow Oak)
This oak looks different from other oaks because of its
leaves. Instead of having wide leaves with lobes, it has
slender, willow-like leaves. It typically grows in warmer
climates but can, at times, survive our harsher winters.
Quercus michauxii (Swamp Chestnut Oak)
This is another oak that normally grows in warmer climates.
It is also called basket oak for the baskets made from its
wood and cow oak because cows like to eat its acorns.
Carya × nussbaumeri (Hican)
This tree is a hybrid of pecan and shellbark hickory. It was
developed to produce a nut with the taste of pecans but
with the weaker shell of shellbark hickory.
Cercidiphyllum japonicum (Katsuratree)
The Katsuratree has a leaf that is similar in shape to that
of the eastern redbud, except for the rounded teeth found
in this species. This tree will grow to be 40 to 60 feet tall
with an oval shape.
Fraxinus americana 'Junginger' [sold as Autumn Purple®] (Autumn Purple White Ash)
Its straight, clean form and springy wood have made this
tree a favorite since the time of the pioneers. Uses for
the wood include skis, tool handles, baseball bats, and
crutches. Ash also provides excellent fuel wood. Ash was
frequently used as a landscape tree but the arrival of the
emerald ash borer to our area makes it a poor choice for
Fagus sylvatica 'Purpurea' (Purple-Leaf European Beech)
This species is similar to the American beech but has a darker gray bark. It grows up to 60 feet tall and 45 feet wide. This tree is growing at the site of John Purdue's grave.
Zelkova serrata 'Halka' (Halka Japanese Zelkova)
An Asian cousin to our native elm, this tree has gained popularity in the U.S. because of its resistance to Dutch elm disease and its tolerance of urban conditions. In youth, the bark is a smooth gray with numerous lenticels. As the tree matures, the bark becomes scaly and peels off, exposing oranges and reds.
Quercus acutissima (Sawtooth Oak)
This oak grows best in southern climates. The chestnut-like
leaves are a dark, lustrous green.
Oxydendrum arboreum (Sourwood)
This small tree is also called lilly-of-the-valley tree due to
its drooping clusters of white flowers. The leaves can turn a
brilliant red in the fall.
Cornus florida (Flowering Dogwood)
Dogwood remains a favorite for landscape use. The small
size of the tree lends itself to city plantings, and the
flowers are beautiful. Birds are attracted to the red berries.
Dogwood is the state tree of both Missouri and Virginia.
Robinia pseudoacacia (Black Locust)
Black locust grows faster than many of its eastern forest
companions. Its timber is used for making fence posts and
railroad ties. It resprouts from stumps so readily that it can
take over fence rows, fields, and clearings.
Peirce Pines (Campus Features and Green Initiatives)
These various pines were planted in 1874 by Martin Peirce, whose regular donations of funds and labor changed the campus landscape. They are part of a long row that, at one time, ran from this site to the east side of Stanley Coulter Hall and around toward the Recitation Building. The tall, narrow Douglas fir in front of Recitation was part of that planting.
Tilia americana 'Redmond' (Redmond American Linden)
Basswood, often referred to as linden or linn, has many
useful qualities. Flowers from the basswood tree provide a
rich commercial honey. The ropiness and flexibility of the
wood has proven to be valuable for use in livestock fencing
gates. Native Americans made rope from the inner bark.
Juglans nigra (Black Walnut)
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.
Taxodium distichum (Common Baldcypress)
This tree is one of two species on campus that lose all of
their needles in the fall. The needles come out late in the
spring and give the tree a soft, feathery appearance. They
turn a rich bronze color before dropping.
Quercus macrocarpa (Bur Oak)
Bur oak is native to the central U.S. It is a slow-growing,
stout tree typical of the oak family. It produces an acorn
with conspicuous fringes around the cap.
Ulmus parvifolia 'UPMTF' [sold as Bosque®] (Bosque Lacebark Elm)
This is an upright, pyramidal shaped tree with attractive
multicolored, exfoliating bark. It will grow to a height of 45
feet with a spread of about 30 feet.
