Acer campestre, Hedge Maple
• Also known as field maple• Fruit is a samara with two
winged seeds.• Widely grown as an
ornamental tree in parks and large gardens.
• The wood is white, hard and strong, and used for furniture, flooring, wood turning and musical instruments.
• There are over 30 known cultivars of Acer campestre.
• Native to western North America• Always within 300 km of the
Pacific Ocean coast• Most commonly grows as a large
shrub growing to around 5-8 m tall, but it will occasionally form a small to medium-sized tree
• Vine Maple trees can bend over easily. Sometimes, this can cause the top of the tree to grow into the ground and send out a new root system, creating a natural arch.
• It is a slender deciduous tree that reaches a height of up to 30 m tall but is usually smaller.
• Smooth, gray bark • Rarely seen in cultivation
outside of arboreta• Spectacular fall color that
includes pink and orange tones
The leaves have a 7-10 cm petiole and three leaflets; the leaflets are short-stalked, oblong, 5-10 cm (2-4 inches) long and 1.5-3 cm broad, with serrated margins, the central leaflet the same size as or slightly larger than the two side leaflets.
Celtis occidentalis, Hackberry• The Common Hackberry is easily
distinguished from elms and some other hackberries by its cork-like bark with wart-like protuberances.
• The leaves are distinctly asymmetrical and coarse-textured.
• Instead of sending out seeds in samaras like the elm, the hackberry produces its seeds as small berries, hackberries, that are eaten by a number of birds and mammals.
• Hackberry's wood is soft and rots easily, making the wood undesirable commercially.

Prunus serotina, Black Cherry• This cherry is native to eastern
North America• Its black bark has the appearance
of very thick, burnt potato chips.• It can also quickly be identified
by its long, shiny leaves resembling that of a Sourwood, and by an almond-like odor when a young twig is scratched and held close to the nose.
• The fruit is suitable for making jam, cherry pies.
• The timber is valuable, perhaps the premier cabinetry timber of the U.S., traded as "cherry". The grain is so smooth that pores can be detected only with a magnifying glass.
• Native to much of Europe from Ireland and southern Scandinavia in the north, to northern Spain and Sicily in the south, and as far east as Lithuania, Asia Minor and up to the Caucasus.
• The hermaphrodite flowers are produced in late spring and are insect-pollinated.
• The fruit is poisonous.• European Spindle wood is very
hard, and can be cut to a very sharp point; it was used in the past for making spindles for spinning wool.
• 5-7 leaflets of a leaf come out from a single point of attachment called palmately compound

Aesculus hippocastanum ‘Baumanii’, European Horsechestnut
• Large deciduous tree• The leaf scars left on twigs after
the leaves have fallen have a distinctive horseshoe shape, complete with seven "nails".
• The common name horse-chestnut is reported as having originated from the erroneous belief that the tree was a kind of chestnut, together with the observation that eating them cured horses of chest complaints.
A selection of fresh conkers from a horse-chestnut.
• Aesculus × carnea is a hybrid between the Red Buckeye (A. pavia) and the Common Horse-chestnut (A. hippocastanum).
• It is a popular tree in large gardens and parks, most commonly the selected cultivar 'Briotii' (named in 1858 to honor Pierre Louis Briot, the nurseryman at Trianon-Versailles near Paris, France), which has 10-inch tall, deep rosy flowers and matures as a smaller tree.
Aesculus octandra, Yellow Buckeye• The flowers are produced in
panicles in spring, yellow to yellow-green, each flower 2–3 cm long with the stamens shorter than the petals (unlike the related Ohio Buckeye, where the stamens are longer than the petals).
• The fruit of the Yellow Buckeye is poisonous to humans but can be made edible through a leaching process.
• The tree species Aesculus glabra is commonly known as Ohio buckeye, American buckeye, or fetid buckeye. It derives its unflattering common name from the disagreeable odor generated from the flowers, crushed leaves, broken twigs, or bruised bark.
• The fruits contain tannic acid, and are poisonous for cattle, and possibly humans. Native Americans would blanch them, extracting the tannic acid for use in leather.
• The buckeye nuts can also be dried, turning dark as they harden with exposure to the air, and strung onto necklaces. These are particularly popular among Ohio State fans.
Larix laricinda, Tamarack• Tamarack Larch, or Tamarack, or
Hackmatack, or American Larch is a species of larch native to northern North America and Canada
• The Larch is a deciduous conifer. The needles turn yellow in autumn.
• Larch are commonly found in swamps, bogs, and other low-land areas.
• The wood is tough and durable, but also flexible in thin strips, and was used by the Algonquian people for making snowshoes and other products where toughness was required.
known as poison ivy (older synonyms are Rhus toxicodendron and Rhus radicans), is a poisonous North American plant.
• Poison ivy can be found growing in any of the following three forms:– as a trailing vine that is 10–25 cm
tall (4 to 10 inches)– as a shrub up to 1.2 m tall (4 feet)– as a climbing vine that grows on
trees or some other support
• The following three characteristics are sufficient to identify poison ivy in most situations: (a) clusters of three leaflets, (b) alternate leaf arrangement, and (c) lack of thorns.
Toxicodendron radicans or poison ivy

Platanus occidentalis, Sycamore• An American sycamore tree can often
be easily distinguished from other trees by its mottled exfoliating bark, which flakes off in great irregular masses, leaving the surface mottled, and greenish-white, gray and brown, like a soldier’s camouflage uniform.
• The explanation is found in the rigid texture of the bark tissue, which lacks the elasticity of the bark of some other trees, so it is incapable of stretching to accommodate the growth of the wood underneath and the tree sloughs it off to expose the inner bark.
• The terms under which the New York Stock Exchange was formed is called the "Buttonwood Agreement", because it was signed under a buttonwood (sycamore) tree at 68 Wall Street, New York City, in 1792.
Liriodendron tulipifera, Tuliptree• Commonly known as the tulip tree,
American tulip tree, tuliptree, tulip poplar or yellow poplar
• Liriodendron tulipifera is one of two species in the genus Liriodendron in the magnolia family.
• It is also called the tuliptree Magnolia, or sometimes confusingly, by the lumber industry, as the tulip poplar or yellow poplar, although it is unrelated to the poplars
• The flowers are large, brilliant, greenish yellow with dashes of red and orange, and their resemblance to a tulip very marked.
• Native Americans so habitually made their dugout canoes of its trunk that the early settlers west of the Appalachian Mountains called it Canoewood.
• This tree species is a major honey plant in the eastern United States, yielding a dark reddish, fairly strong honey which gets mixed reviews as a table honey but is favorably regarded by bakers.
Ginkgo biloba, Ginkgo• Known as the Maidenhair Tree, is a unique
species of tree with no close living relatives.
• The old popular name "Maidenhair tree" is because the leaves resemble some of the pinnae of the Maidenhair fern.
• The tree is widely cultivated and introduced, since an early period in human history, and has various uses as a food and traditional medicine.
• The leaves are unique among seed plants.• Ginkgos are dioecious, with separate sexes,
some trees being female and others being male.
• It is one of the best-known examples of a living fossil, because Ginkgoales other than G. biloba are not known from the fossil record after the Pliocene.
• Extreme examples of the Ginkgo's tenacity may be seen in Hiroshima, Japan, where six trees growing between 1–2 km from the 1945 atom bomb explosion were among the few living things in the area to survive the blast .The trees are alive to this day.
• Species of maple closely related to A. saccharum (Sugar Maple), and treated as a subspecies of it by some authors
• Identification can be confusing due to the tendency of the two species to form hybrids.
• The simplest and most accurate method for distinguishing between the two trees is the three-lobed leaves of the Black Maple versus the five-lobed leaves of the Sugar Maple.
• This species is used similarly to the A. saccharum, for timber and for maple syrup production.
Acer rubrum, Red Maple• Acer rubrum (Red Maple, also
known as Swamp or Soft Maple), is one of the most common and widespread deciduous trees of eastern North America.
• It is best known for its brilliant deep scarlet foliage in autumn.
• The buds of red maple and other soft maples emerge much earlier in the spring than the sugar maple, and after sprouting chemical makeup of the sap changes, imparting an undesirable flavor to the syrup. Red maple can only be tapped for syrup before the buds emerge, making the season very short.
Fagus grandifolia, American Beech• The tree is monoecious, with flowers
of both sexes on the same tree. • Like the European Beech bark, the
American Beech bark is an attraction for vandals who carve names, dates, gang symbols, and other material into it.
• Beech nuts were one of the primary foods of the now-extinct passenger pigeon, and the clearing of beech and oak forests are pointed to as one of the major factors that may have contributed to the bird's extinction. The beech’s love for good soil signaled to the settlers that the land where it flourished was rich and fertile. So American Beeches were cleared away en masse to make room for farms. Foliage, Fagus grandifolia
Cercis canadensis, Redbud• In some parts of southern
Appalachia, green twigs from the Eastern redbud are used as seasoning for wild game such as venison and opossum. Because of this, in these mountain areas the Eastern redbud is sometimes known as the spicewood tree.
• The redbud is the state tree of Oklahoma.
• Native Americans consumed redbud flowers raw or boiled, and ate roasted seeds.
The flowers are pollinated by long-tongued bees such as blueberry bees and carpenter bees. Short-tongued bees apparently cannot reach the nectaries.

• It is commonly found at and immediately below the tree line.
• The cones are erect, 6–12 cm long, dark blackish-purple with fine yellow-brown pubescence, ripening brown and disintegrating to release the winged seeds in early fall.
• The wood is used for general structural purposes and paper manufacture. It is also a popular Christmas tree.
• Prunus serrulata or Japanese Cherry; also called Hill Cherry, Oriental Cherry or East Asian Cherry, is a species of cherry native to Japan, Korea and China. It is known for its spring cherry blossom displays and festivals.
• The National Cherry Blossom Festival is a spring celebration in Washington, D.C., commemorating the 1912 gift of Prunus serrulata Japanese cherry trees from Tokyo to the city of Washington. They are planted in the Tidal Basin Park.
Abies lasiocarpa var. arizonica,Rocky Mountain Fir
• The Corkbark Fir Abies lasiocarpa var. arizonica occurs in Arizona and New Mexico. It differs in thicker, corky bark and more strongly glaucous (frosted appearance) foliage
• Cones on fir trees stand upright like candles (on other conifers the cones hang down) and they rapidly disintegrate.
Abies balsamea, Balsam Fir• The balsam fir (Abies balsamea)
is a North American fir.• Both varieties of the species are
very popular as Christmas trees, particularly in the northeastern United states.
• The resin is used to produce Canada balsam, and was traditionally used as a cold remedy and as a glue for glasses, optical instrument components, and for preparing permanent mounts of microscope specimens. The wood is milled for framing lumber,siding,and pulped for paper manufacture. Balsam fir oil is an EPA approved nontoxic rodent repellent.
• Chionanthus virginicus (White Fringetree) is a tree native to the eastern United States, from New Jersey south to Florida, and west to Oklahoma and Texas.
• It is a deciduous shrub or small tree growing to as much as 10–11 m tall, though ordinarily less.
• Said to be Thomas Jefferson’s favorite tree, it is covered by fleecy panicles of white blossoms in late May and early June. Female blossoms produce dark ege shaped fruit, called drupes, which are quite noticeable in August.
• The dried roots and bark were used by Native Americans to treat skin inflammations.
• It is a medium-sized evergreen tree growing to 25-40 m tall, and with a trunk diameter of up to 1.5 m.
• The species is currently not listed as threatened, but recently population numbers have been declining due to deforestation caused by the Chinese logging industry.
• P. asperata is occasionally grown as an ornamental tree in Europe and North America.
Immature Picea asperata growing in the Jiuzhaigou Valley, Sichuan, China
• Also known as silver birch• Silver Birch is often planted as
a garden and ornamental tree, grown for its white bark and gracefully drooping shoots, sometimes even in warmer-than-optimum places such as Los Angeles and Sydney.
• Silver Birch is Finland's national tree.
• Occasionally one uses leafy, fragrant boughs of Silver Birch to gently beat oneself in a sauna. Betula pendula 'Laciniata'
Picea meyeri, Meyers Spruce• It is occasionally planted as
an ornamental tree; its popularity is increasing in the eastern United States, where it is being used to replace Blue Spruce, which is more disease-prone in the humid climate there.
• It is virtually identical to the Colorado Blue Spruce.
• It is closely related to the Dragon Spruce from western China.
Picea abies, Norway Spruce• Norway Spruce (Picea abies) is a
species of spruce native to Europe. It is also commonly referred to as the European Spruce.
• The Norway Spruce is one of the most widely planted spruces.
• It is also widely planted for use as a Christmas tree.
• Every Christmas, the Norwegian capital city, Oslo, provides the cities of New York, London, Edinburgh and Washington D.C. with a Norwegian spruce, which is placed at the most central square of each city. This is mainly a sign of gratitude for the aid these countries gave during the Second World War.
• The cones are 9–17 cm long (the longest of any spruce).
These cones are the models for cast-iron weights on cuckoo clocks.
Picea amorika, Serbian Spruce• Deer-resistant and very
narrow, it achieves a two-tone look from the silvery undersides of its blue-green needles.
• Best in rich, deep soil, this exceedingly slow-growing tree is very easy to care for.
• Columnar and only needs a 10 or 12 foot square area.

Gleditsia triancanthos var. inermis,Thornless Honeylocust
• Spread is usually equal to height.
• Some trees become nearly flat-topped.
• Use maybe should be tempered in light of past overuse and urban monoculture of honeylocust.
• These plants do not produce thorns of their stems
53
Gymnocladus dioicus, Kentucky Coffeetree
• Europeans first encountered it in Kentucky.
• When spring comes, it gives no apparent recognition of light and warmth until nearly every other tree is in full leaf.
• Is considered a rare tree species
• Native Americans and early Europeans used the beans from the pods as an inferior substitute for real coffee.

Thuja occidentalis, White Cedar• Thuja occidentalis (Eastern
Arborvitae, Northern Whitecedar) is an evergreen coniferous tree, in the cypress family Cupressaceae, which is widely cultivated for use as an ornamental plant known as American Arbor Vitae.
• The foliage of Thuja occidentalis is rich in Vitamin C and is believed to be the annedda which cured the scurvy of Jacques Cartier and his party in the winter of 1535–1536.
• White cedar is the preferred wood for the structural elements, such as ribs and planking, of birchbark canoes and the planking of wooden canoes.
• It is a deciduous large shrub growing to 4 m tall, spreading by stoloniferous root sprouts.
• The flowers are deep to bright red, rarely yellow and blooms in early spring (name comes from lingering autumn colors).
• The fruit is a hard woody capsule 10–15 mm long, which splits explosively at the apex at maturity one year after pollination, ejecting the two shiny black seeds up to 10 m distant from the parent plant.
• Hamamelis virginiana is a species of Witch-hazel native to eastern North America, from Nova Scotia west to Minnesota, and south to central Florida to eastern Texas.
• It is a deciduous large shrub growing to 6 m (rarely to 10 m) tall, with a dense cluster of stems from the base.
• The flowers are pale to bright yellow blooming in late fall.
• The forked twigs of Witch Hazel are preferred as divining rods.
• It is recognizable from its combination of five-pointed star-shaped leaves and spiked fruit.
• A popular ornamental tree in North America
• The earliest record of the tree appears to be in a Spanish work by F. Hernandez, published in 1651, in which he describes it as a large tree producing a fragrant gum resembling liquid amber, hence the name.
• The fruit, popularly nicknamed a "space bug", "monkey ball", "bommyknocker", "bir ball", "gumball", "conkleberry", "cukoo-bir" or "sticky ball", is a hard, dry, globose, compound fruit 2.5–4 cm in diameter and composed of numerous (40-60) capsules.
• The autumnal coloring is not simply a flame, it is a conflagration; in reds and yellows it equals the maples.
Tilia spp, Basswood or Linden• Tilia is a genus of about 30 species of
trees.• They are generally called lime in Britain
and linden or basswood in North America.• The leaves of all the Tilia species are
heart-shaped and most are asymmetrical, and the tiny fruit, looking like peas, always hang attached to a curious, ribbon-like, greenish yellow bract, whose use seems to be to launch the ripened seed-clusters just a little beyond the parent tree.
• One way to identify a basswood is the presence of “sisters” around the base of the tree.
• It is a popular wood for model building and intricate carving.
• Basswoods are very important honey plants for beekeepers, producing a very pale but richly flavored monofloral honey, perhaps the best flavored honey in the Midwest.
Acer ginnala, Amur Maple• Acer ginnala is a deciduous
spreading shrub or small tree growing to 3-10 m tall, with a short trunk up to 20-40 cm diameter and slender branches.
• Amur Maple is closely related to Acer tataricum (Tatar Maple), and some botanists treat it as a subspecies A. tataricum subsp. Ginnala.
• Acer ginnala is grown as an ornamental plant in northern regions of Europe and North America, where it is the most cold-tolerant maple, hardy to zone 2.
• It is a nonnative invasive species in parts of northern America.
• It is also valued in Japan and elsewhere as a species suitable for bonsai.
Quercus alba, White Oak• White oak is our Illinois state tree.• It is one of the pre-eminent
hardwoods of eastern North America.• It is identified by the strong branches
that grow at right angles to the trunk and the distinctive lobed leaves that do not have bristles at the end. The autumn leaves, although brown, are often retained throughout the winter, so if you see a tree in winter in northern Illinois that still has leaves on it, it is likely an oak.
• The bark is usually light grey.• It was a signature wood used in
mission style oak furniture by Gustav Stickley in the Craftsman style in the Arts and Crafts movement. Bark on a large trunk.
Being the subject of a legend as old as the colony itself, the Charter Oak of Hartford, Connecticut is one of the most famous white oaks in America. The tree now makes up the reverse side of the Connecticut state quarter.
Quercus rubra, Northern Red Oak• Often simply called "red oak",
northern red oak is formally so named to distinguish it from southern red oak (Q. falcata), also known as the Spanish oak.
• Northern red oak is easy to recognize by its bark, which feature bark ridges that appear to have shiny stripes down the center, and is the only oak with the striping all the way down the trunk.
• The northern red oak is one of the most important oaks for timber production in North America. The wood is of high value.
• Red oak wood grain is so open that smoke can be blown through it from end-grain to end-grain on a flat-sawn board.
Quercus bicolor, Swamp White Oak• A medium-sized tree of the
north central and northeastern mixed forests. It has a very large range, and can survive in a variety of habitats.
• It is not found where flooding is permanent, although it is usually found in broad stream valleys, low-lying fields, and the margins of lakes, ponds, or sloughs.
• It is one of the more important white oaks for lumber production.
• In recent years, the swamp white oak has become a popular landscaping tree, partly due to its relative ease of transplanting.
Rhus typhina, Staghorn Sumac• The Staghorn Sumac (Rhus typhina,
synonym: R. hirta) is a deciduous shrub to small tree in the Cashew family, native to eastern North America.
• Staghorn sumac is dioecious, and large clumps can form with either male or female plants.
• The fruit of staghorn sumac is one of the most identifiable characteristics, forming dense clusters of small red drupes at the terminal end of the branches. This fruit was picked and crushed in water by Native Americans to make “Indian tea”, which some say resembles cranberry juice.
• The leaves and berries of staghorn sumac have been mixed with tobacco and other herbs and smoked by Native American tribes. This practice continues to a small degree to this day.
Rhus glabra, Smooth Sumac• One of the easiest shrubs to
identify throughout the year (unless mistaken for Rhus vernix, poison sumac, in the absence of mature fruit) smooth sumac has a spreading, open-growing shrub growing up to 3 m tall, rarely to 5 m.
• The flowers are tiny, green, produced in dense erect panicles 10-25 cm tall, in the spring, later followed by large panicles of edible crimson berries that remain throughout the winter.
Pinus aristata, Bristlecone Pine• Pinus aristata, the Rocky
Mountain Bristlecone Pine, is a very slow growing (1” in diameter in 100 years) species of pine native to the United States.
• There is a living tree in Arizona which is documented as being a seedling back when the Egyptians were building the pyramids!
• It is usually found at very high altitudes
• It has highly characteristic small white resin flecks appearing on the needles which look a bit like 'dandruff' on the needles, is diagnostic of Pinus aristata; no other pine shows it.
Pinus sylvestris, Scotch Pine• Pinus sylvestris is an evergreen
coniferous tree • It is the national tree of
Scotland, and it formed much of the Caledonian Forest which once covered much of the Scottish Highlands.
• It has been widely used in the United States for the Christmas tree trade, and was one of the most popular Christmas trees from the 1950s through the 1980s. It remains popular for that usage, though it has been eclipsed in popularity, by such species as Fraser Fir, Douglas-fir, and others.
Pinus resinosa, Red Pine• In the Upper Midwest of the
United States it is sometimes known as the Norway Pine tree.
• Red Pine is an evergreen tree characterized by tall, straight growth in a variety of habitats.
• The bark is thick and gray-brown at the base of the tree, but thin, flaky and bright orange-red in the upper crown; the tree's name derives from this distinctive character.
• Some red color may be seen in the fissures of the bark. Red Pine is self pruning; there tend not to be dead branches on the trees, and older trees may have very long lengths of branchless trunk below the canopy.
Pinus strobus, Eastern White Pine• It is occasionally known as simply
White Pine, Northern White Pine, or Soft Pine.
• The leaves ('needles') are in fascicles (bundles) of five (rarely 3 or 4), with a deciduous sheath.
• White pine forests originally covered much of northeastern North America.
• The eastern white pine has the distinction of being the tallest tree in eastern North America.
• Because the tree is somewhat resistant to fire, mature survivors are able to re-seed burned areas. In pure stands mature trees usually have no branches on the lower half of the trunk.
• During the age of sail, tall white pines with high quality wood were known as mast pines.
as blackhaw, Blackhaw Viburnum, sweet haw, or Stag Bush), is a species of Viburnum native to southeastern North America.
• It is a deciduous shrub or small tree growing up to 15 feet tall and 8 to 12 feet wide (2–9 m tall) with a short crooked trunk and stout spreading branches.
• For centuries, black haw has been used for medical purposes, mainly for gynecological conditions. The bark is the part of the plant used in treatments.
• Viburnum rufidulum, also known as the Rusty Blackhaw, is a flowering species of shrub or small tree that is common in parts of the Eastern and Central United States.
Rusty hairs on the leaf underside are a diagnostic characteristic of this species.
Quercus palustris, Pin Oak• Also known as the Swamp
Spanish oak. The specific name palustris means "of swamps".
• When older, some upper branches become quite large and the central leader is lost, while the lower branches gradually droop downwards.
• A characteristic shared by a few other oak species, and also some beeches and hornbeams, is the retention of leaves through the winter on juvenile tissue.
• The name "pin oak" is possibly due to the many small, slender twigs, but may also be from the historical use of the hard wood for pins in wooden building construction.
• Species of false cypress, native to central and southern Japan
• The bark is red-brown, vertically fissured and with a stringy texture.
• It is grown for its timber in Japan, where it is used as a material for building palaces, temples, shrines and baths, and making coffins.
• It is also a popular ornamental tree in parks and gardens.
• It has a scaley, golden foliage that is string-like in form. The latter trait is the reason for the designation, "Filifera," which is Latin for "thread-bearing"; so in all this confusion of names, "threadleaf," at least, should be easy to remember.
Pinus nigra, Austrian Pine• Also known as the European
Black Pine• The bark is grey to yellow-
brown, and is widely split by flaking fissures into scaly plates, becoming increasingly fissured with age.
• In the United States European Black Pine is planted as a street tree, and as an ornamental tree in gardens and parks. Its value as a street tree is largely due to its resistance to salt spray (from road deicing salt).
• Juniperus communis is a shrub or small tree, very variable and often a low spreading shrub, but occasionally reaching 10 m tall.
• The cones are used to flavor gin. In fact, the word 'gin' is derived from the French word for juniper berry, genièvre, which is the name for gin in France.
• Juniper berries have long been used as medicine by many cultures. Native Americans used them as a herbal remedy for urinary tract infections.
Juniperus communis subsp. communisin the Netherlands
• J. chinensis is a popular ornamental tree or shrub in gardens and parks, with over 100 named cultivars selected for various characters.
• The hybrid between Juniperus chinensis and Juniperus sabina, known as Juniperus × pfitzeriana (Pfitzer Juniper, synonym J. × media), is also very common as a cultivated plant. It is only ever a shrub, never a tree, making it suitable for smaller gardens.
• Honey locusts commonly have thorns 3–10 cm long growing out of the branches. These thorns are thought to have evolved to protect the trees from browsing Pleistocene megafauna.
• The fruit of the Honey locust is a flat legume (pod) that matures in early autumn. The name derives from the sweet taste of the legume pulp, which was used for food by Native American people, and can also be fermented to make beer.
A honey locust in Washington state show its fall color.
Quercus velutina, Black Oak• The eastern black oak or more
commonly known as simply black oak, is an oak in the red oak group of oaks.
• It is a common tree in the Indiana Dunes and other sandy dunal ecosystems along the southern shores of Lake Michigan.
• Black oak is well known to readily hybridize with other members of the red oak (Quercus sect. Lobatae) group of oaks being one parent in at least a dozen different named hybrids.
known as Sargent's cherry, North Japanese hill cherry, Ezo mountain cherry or Big mountain cherry in Japan, is a species of cherry native to Japan, Korea, and Sakhalin (Russia).
• The tree one of the hardiest cherries and can be easily transplanted. This makes the tree suitable for use as a street tree.
• Its bark is a rich polished reddish to chesnut brown.
• The European Beech or Common Beech, is a deciduous tree belonging to the beech family Fagaceae.
• It is a large tree, capable of reaching heights of up to 49 m (160 ft) tall and 3 m (10 ft) trunk diameter, though more typically 25–35 m (80–115 ft) tall and up to 1.5 m (5 ft) trunk diameter.
• It is frequently kept clipped to make attractive hedges.
• The cucumber magnolia or blue magnolia, is one of the largest magnolias, and one of the cold-hardiest.
• Unlike most magnolias, the flowers are not showy. They are typically small, yellow-green, and borne high in the tree in April through June. Up to 10” long leaves
• The name Cucumber tree comes from the unripe fruit, which is green and often shaped like a small cucumber.
• Magnolia tripetala, commonly called Umbrella magnolia or simply Umbrella-tree, is a deciduous tree native to the southeastern United States in the Appalachian Mountains region.
• These trees are attractive and easy to grow. The leaves turn yellow in the autumn. The leaves can be up to 20” long.
• The flowers are large, 15-25 cm diameter, with six to nine creamy-white petals and a large red style, which later develops into a red fruit 10 cm long, containing several red seeds.
Cultivated specimen at Morton Arboretum Immature fruit.
• Flowering dogwood is a small deciduous tree growing to 10 m (33 ft) high, often wider than it is tall when mature, with a trunk diameter of up to 30 cm (1 ft). A 10-year-old tree will stand about 5 m (16 ft) tall.
• Other old names now rarely used include American Dogwood, Florida Dogwood, Indian Arrowwood, Cornelian Tree, White Cornel, False Box, and False Boxwood.
• The hard, dense wood has been used for products such as golf club heads, mallets, wooden rake teeth, tool handles, jeweler’s boxes and butcher’s blocks.
Quercus macrocarpa,Bur Oak• the Bur Oak, sometimes spelled
Burr Oak, is a species of oak in the white oak section Quercus sect. This plant is also called Mossycup oak and Mossycup white oak. The acorns are the largest of any North American oak
• One of the most massive oaks with a trunk diameter of up to 3 m (10 ft); It is also a fire-resistant tree.
• Heavy nut crops are borne only every few years. In this strategy, known as masting, the large seed crop every few years overwhelms the ability of seed predators to eat the acorns, thus ensuring the survival of some seeds.
