Carya cordiformis (Bitternut Hickory)
Bitternut hickory earns its name. Squirrels eat the nuts
from this tree only after other food sources are exhausted.
Bitternut produces a tough, strong lumber and is the most
Tsuga canadensis (Canadian Hemlock)
Its dense texture makes Canadian hemlock a popular
evergreen. It can be pruned as a hedge or allowed to grow
to its full height. The bark from this tree was used by Native
Americans to make a paste that would draw out venom and
act as an antiseptic. This plant is in no way associated with
the hemlock poison drunk by the philosopher Socrates.
Picea omorika (Serbian Spruce)
Serbian spruce is noted for its narrow, upright form. It can
grow to 60 feet tall and still have a spread of no more than
15 feet. The dark green needles with two white lines on the
lower surface are another prominent feature of this tree.
Fagus grandifolia (American Beech)
Beech is one of the most distinctive trees of North America.
It is notable for its smooth gray bark and spreading crown.
Beech has a natural tendency to hollow and rot. This
condition is often aggravated by carvings made in the bark
Acer pseudoplatanus (Sycamore Maple)
A native of Europe and western Asia, this tree is best known
for its resistance to damage caused by road salt. This
characteristic has made the sycamore maple a desirable
tree in some areas despite its lack of fall color.
Diospyros virginiana (Common Persimmon)
Persimmon occurs in moist bottomlands from Connecticut
to Texas. The chunky bark on most persimmon trees
resembles alligator skin. Persimmon has little commercial
value with one unique exception: its hard, dense wood is
highly favored for golf club heads.
Ulmus × 'Homestead' (Homestead Elm)
The Homestead elm is a relatively new hybrid. It grows
rapidly and takes on the vase shape of American elm as
it matures. The species is reported to be very resistant to
Dutch elm disease and phloem necrosis, two diseases that
have destroyed most American elms in our area.
Cercis canadensis (Eastern Redbud)
Redbud is beautiful for its form and pink spring flowers.
The most notable use for redbud is landscape and
ornamental plantings. Redbud is the Oklahoma state tree.
Syringa reticulata (Japanese Tree Lilac)
This species of lilac will grow to be 20 to 30 feet tall. It
has large clusters of creamy white flowers in mid-June.
The bark is glossy and reddish-brown, resembling that of
a cherry tree.
Quercus × warei 'Long' [sold as Regal Prince®] (Regal Prince Oak)
A cross between columnar English oak and swamp white
oak, this tree has glossy green leaves that are mildew
resistant. It is noted for its excellent columnar form with a
mature size of up to 45 feet high and 18 feet wide.
Tilia tomentosa (Silver Linden)
Silver linden is similar to American linden (basswood), but
with the difference of a silvery-white undersurface to the
leaves. The flowers bloom in early July and are very fragrant.
Pinus cembra (Swiss Stone Pine)
This pine is a slow grower but holds its pyramidal shape
well into maturity. The long, flexible needles grow in groups
of five, similar to eastern white pine.
Gleditsia triacanthos f. inermis (Thornless Common Honeylocust)
Native to the central U.S., the honey locust has filled a
void left by the deaths of many streetside elms. It has a
pleasing form and natural hardiness. Reproduction and
dispersement are accomplished by means of a seed pod
that drops from the tree during winter. Many seedless
varieties are now available.
Liquidambar styraciflua (American Sweetgum)
Sweetgum is notable for leaves that are shaped like
five-pointed stars during the summer, and for spiny
seed-carrying balls that appear in the fall.
Quercus montana (Chestnut Oak)
Chestnut oak is at home in the Appalachian Mountains.
It can be found growing on poor, dry upland sites in pure
stands. The bark contains a chemical called tannin, which
is used in the preparation of tanned leather.
Acer buergerianum (Trident Maple)
Trident maple is originally from Japan and was first brought
to the U.S. in 1892. An interesting feature is its bark, which
naturally peels in patches. This species usually does not
grow more than 30 feet tall. The leaves turn to a beautiful
combination of orange and red in the fall.
Ilex opaca (American Holly)
This attractive tree displays spiny evergreen leaves and red
berries that are used during the Christmas season. It’s one
of the few trees that does not produce bark, but instead
retains its original outer layer of cells.
Taxodium distichum var. imbricarium (Pondcypress)
Pondcypress is similar to the common baldcypress but with
a more columnar form. As with baldcypress, this tree drops
its needles each fall and grows new ones in the spring.
Pinus sylvestris (Scotch Pine)
Originally from the Scottish Highlands, Scotch pine is the
most widely planted tree in the world. It is used extensively
for timber and ornamental purposes, and it is extremely
popular as a Christmas tree.
Ostrya virginiana (American Hophornbeam)
Due to its small size, ironwood is often excluded from the
limelight given to many of its eastern forest companions.
Yet the tree decorates the understory with its twisted form
and scaly bark. Ironwood is just what the name implies:
dense and strong.
Stewartia pseudocamellia (Japanese Stewartia)
Stewartia is a small tree native to Japan with beautiful,
camellia-like flowers in the spring. It has attractive,
exfoliating bark and the leaves turn red to dark
reddish purple in the fall.
Halesia carolina (Carolina Silverbell)
Carolina silverbell is a small tree or large shrub whose small white flowers emerge with leaves in the spring and develop into interesting four-winged fruits.
Celtis occidentalis (Common Hackberry)
This relative of the elm with its warty bark grows best in
fairly moist soils. A variety of birds including robins,
pheasants, and grouse eat its fruit.
Liquidambar styraciflua (Shuttle Gum Group) (American Sweetgum)
This sweetgum tree was germinated in August 1984 aboard
the space shuttle Discovery. Purdue astronaut Charles
Walker of Bedford, Indiana, brought back 200 tiny trees;
these recognize Purdue’s many astronauts.
Aesculus glabra (Ohio Buckeye)
The state tree of Ohio, buckeye grows along the streams of
the eastern U.S. It is the first tree to leaf out in the spring
and the first to drop its leaves in the fall. It produces a hard
brown fruit that is highly toxic.
Cornus kousa (Kousa Dogwood)
This species is similar to the flowering dogwood, but
it flowers three to four weeks later. Fruits resemble
raspberries and are sought after by wildlife. Like the native
dogwood, the leaves turn a deep scarlet in the fall.
Chionanthus virginicus (White Fringetree)
The large, white, feathery clusters of flowers are the
outstanding feature of this tree. The blossoms can be seen
from early April to late May and develop into dark blue,
grape-like fruits that attract wildlife. This is a small tree that
will grow to be 12 to 20 feet in height with an equal spread.
Maclura pomifera (Osage-orange)
Osage orange, also called hedgeapple, is native to
Oklahoma, Arkansas, and Texas. Midwesterners soon
discovered that it would grow anywhere and that it made
an excellent livestock hedge. Hedgeapple bears a large,
green, apple-like fruit in late summer. Pioneers used this
fruit as a pest repellent by storing pieces of it around the
foundations of buildings.
Acer × freemanii 'Jeffersred' [sold as Autumn Blaze®] (Autumn Blaze Maple)
This cross between red maple and silver maple has the hardiness of the silver maple combined with the beautiful red fall color of the red maple. It grows quickly and the bark may be more susceptible to frost cracks than other species.
