The wood is used commercially as a "soft" hardwood. Its rapid growth has encouraged the overuse of silver maple as a shade tree. However, the brittle branches are easily broken in ice storms and windstorms and the abundant fruit produces litter. Special notes: this is one species which should be avoided in yard plantings. Identifying Characteristics Height 90 ft Spread 90 ft Leaves Opposite, simple, 4" - 6" in diameter; 5 lobes, edges coarsely toothed, pale green above, silvery below Flowers In clusters along twigs, reddish green Fruit Winged seed in pairs Bark Silvery-gray on young trees; older bark gray, breaking into long thin scaly plates Associated species Sweet gum, green ash, river birch, hackberry, pin oak Ideal site conditions Wet soil, partial sun Value to man Erosion, wood products Value to wildlife Food, dens Growth Rate Fast Range 2 Sugar Maple Acer saccharum Sugar maple becomes a very large shade tree that is well-known for fall colors ranging from yellow to orange to shades of red. It is less pollution tolerant than red maple, especially to de-icing salts along roadways. Sugar maple thrives in deep, rich soils. It tolerates poor sites with good drainage, but grows slowly. It needs plenty of space and therefore should be used in large yards, parks, golf courses or similar locations. In shallow soils and other poor sites, leaf scorch may develop during dry periods. Its dense shade and shallow roots prevent a good lawn from growing beneath it. Sugar maple is tolerant of shade and can be used near taller trees or buildings. Many cultivars exist to provide a variety of shapes, fall color and drought tolerance. These should be selected when available. Some are `Green Mountain,' `Legacy,' `Bonfire,' and `Caddo.' Sugar maples grown from seed are much less predictable. Hardiness Zones: 4-8 3 Eastern Cottonwood http://www.mdc.mo.gov/forest/IandE/MOConservationTreesAndShrubs/cottonwood.html http://mdc.mo.gov/nathis/plantpage/flora/motrees/p10.htm Populus deltoides Cottonwood is one of the largest and fastest growing of the eastern hardwoods. It makes its best growth on deep, moist bottomland soils. The wood is used for boxes, crates, furniture and pulpwood. Cottonwood is short-lived but serves an important function by stabilizing new sandbars and bare flood plains. Identifying Characteristics Height 90 ft Spread 90 ft Leaves alternate, simple, 3" - 6" long; triangular in shape, edges have round teeth, shiny dark green above, paler below; leaf stalk long and flattened Flowers male and female flowers on separate trees; flowers in a catkin Fruit long hanging clusters of green capsules containing cottony seed Bark light greenish-yellow on young stems; older bark light gray, very thick, divided by deep fissures Associated species silver maple, bur oak, river birch, green ash, hackberry Ideal site conditions wet soil, full sun Value to man wood products, erosion Value to wildlife dens, food Growth Rate fast Range 4 Green Ash http://www.mdc.mo.gov/forest/IandE/MOConservationTreesAndShrubs/greenash.html Fraxinus pennsylvanica Green ash is a medium-sized tree distributed throughout the state along streambanks and in moist bottoms. It prefers wet soils but is adaptable to a wide range of site conditions. It has been used for urban plantings, windbreaks and land reclamation. Many varieties of green ash are available commercially. Identifying Characteristics Height: 60 ft Spread: 40 ft Leaves: Opposite, compound, with 7-9 lance-shaped leaflets; each leaflet 3" - 6" long, finely toothed, dark green Flowers: Male and female flowers on separate trees; female flowers green, very small, in clusters Fruit: Winged seed Bark: Gray, ridges cross to form diamond pattern Associated species: Silver maple, hackberry, pin oak, sweetgum, pecan Ideal site conditions Wet soil, full sun Value to man Erosion control, landscaping, wood products, windbreaks Value to wildlife Food, dens Growth Rate Fast Range: 5 American Sycamore http://www.mdc.mo.gov/forest/IandE/MOConservationTreesAndShrubs/asycamore.html http://mdc.mo.gov/nathis/plantpage/flora/motrees/p39.htm Platanus occidentalis Sycamore is one of the largest eastern hardwoods. It is tolerant of wet soil conditions and is found in rich river bottoms. Sycamore can be used to stabilize streambanks along with other bottomland species, where it provides nest sites for large birds such as bald eagles and great blue herons. It is also a pioneer species in old fields. Identifying Characteristics Height 90 ft Spread 90 ft Leaves Alternate, simple, 4" - 8" in diameter with 3-5 main lobes; edges coarsely toothed, yellow-green above, paler below Flowers Tiny; greenish, in 1-2 ball-like drooping clusters Fruit Many seeded ball 1" - 1 l/2" in diameter on a stem 3" - 6" long; each seed attached to a hairy plume Bark Distinctive smooth whitish and mottled bark on upper trunk and branches; lower bark thin, dark brown, scaly Associated species: Cottonwood, sweet gum, river birch, silver maple, green ash, pin oak Ideal site conditions Wet soil, partial sun Value to man Landscaping, wood products, erosion Value to wildlife Dense, cover Growth Rate Fast Range 6 Box Elder http://en.wikipedia.org/wiki/Boxelder (Acer negundo) Box elder is native to portions of the southern tier and Susquehana Valley, but has become more broadly established throughout many parts of the state. Box elder grows commonly along the banks of streams and rivers, and may occur as a weedy species in urban areas where its seeds are able to germinate. Box elder has a soft wood that has no commercial value, but is important for wildlife and the stabilization of stream banks where it grows. Box elder is not recommended for horticultural plantings. Bark - smooth on younger trees but soon developing narrow ridges and shallow furrows. Ridges and furrows are interlacing. Bark on mature trees is dark brown. Twigs - moderate to very stout, smooth and covered with a waxy film giving the twig a shiny green to purple color. Winter buds - white and covered with a hairy scale. Buds held tightly against the twig. Buds are located on the twig within leaf scars having a "v-shaped" notch. Leaves - pinnately compound and opposite, usually 5 leaflets; often resembles poison ivy, which has alternate, pinnately (3 leaflets) compound leaves . Fruit - large clusters of V-shaped samaras; mature in autumn Outstanding features - pinnately compound leaves, purple to green twigs, ridged and furrowed bark 7 American Elm http://mdc.mo.gov/nathis/plantpage/flora/motrees/p28.htm Ulmus americana, generally known as the American Elm or, less commonly, as the White Elm or Water Elm, is a species native to eastern North America, occurring from Nova Scotia west as far as British Columbia, from northern Alberta at the top of its range, south to Florida and central Texas. It is an extremely hardy tree that can withstand winter temperatures as low as −42 °C (−44 °F). Trees in areas unaffected by Dutch elm disease can live for several hundred years. A prime example of the species was the Sauble Elm [3], which grew in Ontario, Canada, to a height of 43 m (140 ft), with a d.b.h of 196 cm (6.43 ft) before succumbing to Dutch elm disease. Felled in 1968, a tree-ring count established that it had germinated in 1701. The American Elm is a deciduous tree, which, before the advent of Dutch elm disease, commonly grew to > 30 m (100 ft) tall with a trunk > 1.2 m (4 ft) d.b.h. Bark The crown forms a high, spreading canopy with open air space beneath. The leaves are alternate, 7–20 cm long, with doubleserrate margins and an oblique base. The tree is hermaphroditic, having perfect flowers, i.e. with both male and female parts, and is therefore capable of self-pollination. The flowers are small, purple-brown, and, being wind-pollinated, are apetalous; they emerge in early spring before the leaves. The fruit is a flat samara 2 cm long and 1.5 cm broad, with a circular wing surrounding the single 4–5 mm seed. Leaves As in the closely related European White Elm, U. laevis, the flowers and seeds are borne on 1–3 cm long stems. American Elm is wholly insensitive to daylight length (photoperiod), and will continue to grow well into autumn until injured by frost [2]. The tree reaches sexual maturity at around 15 years of age and is unique within the genus in being tetraploid, i.e. having double the usual number of chromosomes. However, nowadays it is uncommon for the tree to reach over 10 years of age, such is its susceptibility to Dutch elm disease. 8 Slippery Elm http://mdc.mo.gov/nathis/plantpage/flora/motrees/p28.htm The Slippery Elm Ulmus rubra[2] is a species of elm native to eastern North America (from southeast North Dakota, east to southern Quebec, south to northernmost Florida, and west to eastern Texas). It is similar to American Elm in general appearance, but more closely related to the European Wych Elm, which has a very similar flower structure. Other common names include Red Elm, Gray Elm, Soft Elm, Moose Elm and Indian Elm. The Slippery Elm is a deciduous tree which can grow to 20 m in height with a 50 cm d.b.h.. The tree has a different branching pattern to the other American species, and its heartwood is reddish-brown, giving the tree its alternative common name 'Red Elm'. The leaves are 10-18 cm long and have a rough texture, coarsely double-serrate margin and an oblique base. The perfect windpollinated apetalous flowers are produced before the leaves in early spring, usually in clusters of 10-20. The fruit is an oval winged samara 20 mm long and containing a single, central seed. Slippery Elm may be distinguished from American Elm by the hairiness of the buds and twigs (both smooth on the American Elm) and by its very short-stalked flowers. 9 Hackberry http://www.mdc.mo.gov/forest/IandE/MOConservationTreesAndShrubs/hackberry.html http://mdc.mo.gov/nathis/plantpage/flora/motrees/p31.htm Celtis occidentalis Hackberry is a common bottomland species found over the entire state. It does very well in prairie regions of the state and is used in windbreak plantings. A variety of birds eat the fruit. Identifying Characteristics Height 90 ft Spread 90 ft Leaves alternate, simple, 2" - 5" long, oval, usually sharply toothed; leaf base unequal sided; shiny green Flowers l/8", greenish; at base of young leaves Fruit l/4" - 3/8" in diameter; orange-red to dark purple one-seeded berry Bark gray, smooth, often with corky warts or ridges; becoming scaly on old trees Associated species green ash, silver maple, red mulberry, sycamore Ideal site conditions wide range, partial sun Value to man landscaping, wood products, windbreaks Value to wildlife foodcover Growth Rate medium Range 10 Black Willow http://mdc.mo.gov/nathis/plantpage/flora/motrees/p9.htm Salix nigra (Black Willow) is a species of willow native to eastern North America, from New Brunswick and southern Ontario west to Minnesota, and south to northern Florida and Texas.[2] It is a medium-sized deciduous tree, the largest North American species of willow, growing to 10-30 m tall, exceptionally up to 45 m, with a trunk 50–80 cm diameter. The bark is dark brown to blackish, becoming fissured in older trees. The shoots are slender, variable in color from green to brown, yellow or purplish; they are (like the related European Salix fragilis) brittle at the base, snapping evenly at the branch junction if bent sharply. The foliage buds are small, 2–4 mm long, with a single pointed reddishbrown bud scale. The leaves are alternate, long, thin, 5-15 cm long and 0.5-2 cm broad, usually somewhat falcate, dark, shiny green on both sides or with a lighter green underside, with a finely serrated margin, a short petiole and a pair of small stipules. It is dioecious, with small, green flowers borne on catkins 2.5-7.5 cm long in early spring at the same time as the new leaves appear. The fruit is a 5 mm capsule which splits open when mature to release the numerous minute, down-covered seeds. It is typically found along streams and in swamps.[3][4][5] 11 Bur Oak http://www.mdc.mo.gov/forest/IandE/MOConservationTreesAndShrubs/buroak.html http://mdc.mo.gov/nathis/plantpage/flora/motrees/p21.htm Quercus macrocarpa Bur oak grows on both upland and lowland sites, but does best on rich, moist soils. The acorns of bur oak, distinguished by the very deep fringed cup, are the largest of all native oaks. Its wood is similar to white oak and is used in the manufacture of watertight barrels. Identifying Characteristics Height 85 ft Spread 85 ft Leaves alternate, simple, 6" - 12" long; 5-9 rounded lobes, broadest above the middle, dark green Flowers male flowers in yellow-green catkins; female flowers inconspicuous Fruit acorn, 3/4" - 2" in diameter; with a fringed cap enclosing l/2 to 3/4 of the acorn Bark light gray-brown, thick, divided into large broken ridges at maturity; branches with corky ridges Associated species: shagbark and shellbark hickory, hackberry, northern red oak Ideal site conditions moist soil, full sun Value to man landscaping, wood products Value to wildlife food, cover, dens Growth Rate slow Range 12 White Oak http://mdc.mo.gov/nathis/plantpage/flora/motrees/p19.htm Quercus alba The most important hardwood lumber tree in the United States and Missouri, setting the standard of lumber for all other oaks. The wood is outstanding for making tight barrels for whiskey and other liquids. It makes its best growth in deep, moist well-drained soils of coves and bottomland benches, but is found on a variety of sites throughout the state. Identifying Characteristics Height 85 ft Spread 85 ft Leaves alternate, simple, 5" - 9" long; 7-9 rounded lobes, edges smooth, bright green Flowers male flowers in yellow-green catkins; female flowers inconspicuous Fruit acorn, 3/4" long; shiny brown with a thick warty cap Bark light gray; rough with long loose scales; becoming blocky on very old trees Associated species black oak, northern red oak, hickory, black-gum, flowering dogwood Ideal site conditions moist soil, partial sun Value to man landscaping, wood products Value to wildlife food, cover, dens Growth Rate slow Range 13 Swamp White Oak http://en.wikipedia.org/wiki/Swamp_white_oak The Swamp White Oak (Quercus bicolor), is a species of oak in the white oak section Quercus section Quercus, primarily found in the Midwestern and Eastern Seaboard regions of North America, from southernmost Quebec and southern Maine west to southern Minnesota. It is rare south of the Ohio River. As its name implies, it is a tree of wetlands, but grows farther north than the other wetland white oaks (Swamp Chestnut Oak and Overcup Oak). It is not a large tree, typically growing to 20-25m tall, with the tallest known reaching 29m. Swamp White Oak leaves The bark resembles the White Oak. The leaves are broad ovoid, 12-18 cm long and 7-11 cm broad, always more or less glaucous on the underside, and are shallowly lobed with five to seven lobes on each side, intermediate between the Chestnut Oak and the White Oak. In autumn, they turn brown, yellow-brown, or sometimes reddish, but generally, the color is not as reliable or as brilliant as White Oak can be. The fruit is an acorn, 1.5-2 cm (rarely 2.5 cm) long and 1-2 cm broad, maturing about 6 months after pollination. It forms hybrids with Bur Oak where they occur together in the wild. 14 Black Walnut http://www.mdc.mo.gov/forest/IandE/MOConservationTreesAndShrubs/blackwalnut.html http://mdc.mo.gov/nathis/plantpage/flora/motrees/p11.htm Juglans nigra Black walnut is one of the scarcest and most valuable native hardwoods. It is prized for its nuts and lumber. Walnut grows best on deep, alluvial soils. It is very site sensitive and growth rates decline rapidly with poorer site quality. A chemical in the leaves and nuts will kill some plants such as tomatoes and apples. Special notes: black walnut is the state tree nut. Identifying Characteristics Height 85 ft, Spread 85 ft Leaves alternate, compound, 12" - 24" long with 13-23 leaflets; each leaflet 2" - 4" long, lance-shaped, edges finely toothed, yellow-green Flowers yellow-green catkin Fruit nut, 1" - 1 l/2" in diameter, covered with a thick yellow-green fibrous husk Bark young bark smooth and gray; older bark dark brown and furrowed Associated species: northern red oak, white oak, tulip tree Ideal site conditions moist soil, full sun Value to man food, wood products Value to wildlife food, cover, dens Growth Rate medium Range 15 Bitternut Hickory http://mdc.mo.gov/nathis/plantpage/flora/motrees/p16.htm THERE ARE SEVEN READILY recognizable hickories in Missouri but bitternut hickory is the only hickory tree which has long, sulphur-yellow colored buds. It is widely distributed over the state. The nut is nearly globe-shaped and covered by a thin husk which is partially winged along the lines where it splits. The kernel is bitter but the squirrels don't seem to mind it. For them it is an important winter food which they store in hollow trees and bury in the ground. Forgotten buried nuts become new trees. The leaf, ranging from 6 to 10 inches long, is compound with 7 to 9 elliptically shaped leaflets. They are usually broadest above the center with toothed edges. These leaflets are supported from hairy stalks and are dark yellow-green and smooth above, pale and slightly hairy below. In winter, this tree can be identified by its slender, pale gray twigs which are dotted with corky rises. The bark is nearly smooth and light gray when young, remaining on the trunk for several years. As the tree ages the bark becomes shallowly furrowed with thin interconnecting ridges. Small bitternut hickory trees will grow in dense shade under the tops of sugar maple, white oak, white ash, and black walnut among others and still survive. It is a moderately fast growing tree, but short lived compared with other hickories. Bitternut hickory wood is used to some degree in making handles, but is used largely for making charcoal for outdoor barbecuing. This wood smoke gives meat a rich flavor and aroma. Some meats are smoke cured with hickory because of its distinctive taste. It also makes an excellent fuelwood for cook stoves, furnaces or fireplaces. 16 Shellbark Hickory http://www.mdc.mo.gov/forest/IandE/MOConservationTreesAndShrubs/shellbarkhickory.html http://mdc.mo.gov/nathis/plantpage/flora/motrees/p13.htm Carya laciniosa Shellbark hickory, sometimes called big shagbark hickory, is the largest of the true hickories. Shellbark hickory is found in the fertile bottomland soils along rivers and streams. It occurs throughout most of Missouri with the exception of the Ozarks. Shellbark hickory can be distinguished from shagbark hickory by the larger leaves, greater number of leaflets, large nuts and orange twigs. Special notes: this is the best tasting of Missouri hickory nuts. Identifying Characteristics Height 90 ft Spread 50 ft Leaves alternate, compound, 12" - 24" long, 7 leaflets; each leaflet 5" - 9" long, oval, broadest above the middle, edges finely toothed, dark green Flowers male flowers in catkins, female flowers in spikes at the end of branches Fruit nut, 1 3/4" -2 l/2" in diameter, covered with a thick 4-part husk Bark similar to shagbark hickory Associated species green ash, shagbark hickory, Shumard oak, white oak, sweetgum Ideal site conditions moist soil, partial sun Value to man food, wood products Value to wildlife food, cover, dens Growth Rate slow Range 17 River Birch http://www.mdc.mo.gov/forest/IandE/MOConservationTreesAndShrubs/riverbirch.html Betula nigra River birch is the only birch native to Missouri. It is found throughout Missouri in lowlands and along streambanks. Its ability to thrive on wet sites makes it useful for streambank stabilization. The attractive bark and its resistance to borers make river birch the preferred birch for landscaping. Identifying Characteristics Height 60 ft Spread 40 ft Leaves alternate, simple, 1 l/2" - 3" long, oval to triangular with a sharp point at tip; edges doubly toothed, dark green above, pale yellow-green below Flowers flowers in catkins Fruit 1" long cone-like clusters of small winged seeds Bark light reddish-brown to cinnamon colored; peels off in thin papery layers Associated species sweetgum, pin oak, silver maple, green ash, cottonwood Ideal site conditions moist soilfull sun Value to man landscaping, erosion Value to wildlife dens Growth Rate fast Range 18 Kentucky Coffeetree http://www.mdc.mo.gov/forest/IandE/MOConservationTreesAndShrubs/kentuckycoffeetree.html Gymnocladus dioicus Kentucky coffeetree is distributed throughout the state although it is most common in the western part of Missouri. It rarely grows in pure stands and is usually found growing with other hardwoods. It is a legume and the large persistent seedpods and short, heavy twigs make this tree distinctive in winter. Identifying Characteristics Height 85 ft Spread 65 ft Leaves alternate, doubly compound, 12" - 30" long; the axes with 3-8 pairs of side axes; leaflets 1" - 3" long, oval, dull green Flowers male and female flowers on separate trees; 5/8" - 3/4" long, greenish-white, with narrow tube and 4-5 spreading petals Fruit dark brown, heavy wooden pod, 4" - 7" long; seeds 3/4" in diameter, shiny dark brown Bark gray, deeply furrowed into narrow scaly ridges often curling up on one edge Associated species green ash, silver maple, black walnut, hackberry Ideal site conditions moist soilfull sun Value to man landscapingwindbreakserosion Value to wildlife food Growth Rate slow Range 19 Understory Trees Sandbar Willow http://www.ag.ndsu.edu/trees/handbook/th-3-65.pdf Sandbar Willow (Salix interior) General Description A medium shrub, native along riverbanks, lakes and sloughs throughout most of North Dakota.

Light Full sun. 21 Gray Dogwood http://plants.usda.gov/factsheet/pdf/fs_cora6.pdf Uses Gray dogwood is useful as a low-growing wild hedge which provides summer food and some cover for small animals and birds. Status Please consult the PLANTS Web site and your State Department of Natural Resources for this plant’s current status (e.g. threatened or endangered species, state noxious status, and wetland indicator values). Description Cornus racemosa Lam, gray dogwood, is a thickly branched, slow growing dogwood seldom more than 6 feet high at maturity. Its flowers, which bloom in June or July, are white and loosely clustered, and its white fruit, which appears in September and October, is set off by bright red fruit-stalks. Its leaves are opposite, taper-pointed and oval. Adaptation Gray dogwood has a range of adaptability equaled by few other shrubs, and it tolerates many climatic conditions. Tolerance to shade is considered intermediate. It is not well adapted to coastal plain conditions. Gray dogwood is distributed throughout the northeastern United States. For a current distribution map, please consult the Plant Profile page for this species on the PLANTS Website. Establishment Only seedlings of gray dogwood are practical. All should be planted as early in the spring as possible. When using dogwood for streambank planting, eroded or steep banks should be graded before planting. Plant in the early spring with dormant planting stock. Planting after May will severely reduce chances for success. One-year rooted cuttings or seedlings can be planted vertically into the bank with one or two inches of cutting wood protruding. They should be stuck in a hole large enough to accommodate the root system when well spread. The soil must be tamped well around the roots. Fresh, unrooted hardwood cuttings, easier to handle but less reliable, should be stuck vertically into the bank, leaving one to two inches above ground. A dibble can be used to make a hole. Tamp adequately to provide complete contact between the cutting and the soil. Cuttings may also be buried horizontally two inches deep in damp soil, if the ground is stony. Fresh hardwood cuttings, 3/8 to 1/2 inch at the thick end, 9 inches long, and made while dormant, are ideal. Without cold storage, planting should be done as soon as possible after cutting. Plant both rooted cuttings and unrooted hardwood cuttings on 2 feet spacing in a diamond pattern. When using for wildlife or screening purposes, the planting site should be cultivated to destroy existing vegetation. If not, the sod should be removed from an area two feet across for each plant. The holes should be deep enough to allow for the full extension of the roots. Spacing for hedges and screens should be staggered and 2 x 2 feet, and 4 to 5 feet for windbreaks. A small handful of fertilizer can be placed around each plant. Management Dogwoods used on streambanks are subject to mechanical damage. The site should be inspected annually for needed repairs in the spring after heavy runoff or ice floes. Fill in gaps by replanting or by laying down and covering branches of nearby plants. Any mechanical measures used to control the bank, Chris Miller USDA NRCS Plant Materials Program such as riprap, must be kept in repair to maintain effective protection. Competing vegetation should be controlled around all dogwood plants used for hedges, screens, etc. This is particularly important during the first few years after planting. Pests and Potential Problems There are currently no serious pests of gray dogwood. Cultivars, Improved, and Selected Materials (and area of origin) No cultivars are available at this time, however common seedlings are available at most commercial hardwood nurseries. Prepared By & Species Coordinator: USDA NRCS Plant Materials Program 22 Swamp Dogwood http://plants.usda.gov/factsheet/pdf/fs_cofo.pdf Uses Wildlife: Fruits are eaten by several species of birds including quail, catbirds, mockingbirds, robins, and brown thrashers. Recreation and Beautification: Excellent landscape tree for its very attractive form and profuse white flowers. Frequently used for massing or naturalizing, screen and border. Status Please consult the PLANTS Web site and your State Department of Natural Resources for this plant’s current status (e.g. threatened or endangered species, state noxious status, and wetland indicator values). Description Cornus foemina P. Mill., swamp dogwood, is primarily found along the coastal plain from eastern Virginia to central Florida, west to Louisiana and north to southeastern Missouri. It is a deciduous small tree to large shrub, growing to 15 ft in height, with multiple trunks, 4 inches in diameter. Its bark is thick and smooth, frequently furrowed with shallow ridges exposing gray inner bark. The plant’s leaves are opposite and oval-shaped, with smooth margins. Flowers are creamy white, loose, and small; they occur in flat topped clusters without showy bracts. Fruits are small, open clusters of bluish to purple drupes (fleshy, oneseeded fruits). Adaptation and Distribution Swamp dogwood generally grows in swampy, low wetland habitats, barrier islands, and along streams, riverbanks, marshes and creeks. It is found growing along ditches on the second road back from the ocean at Emerald Isle and found to exhibit moderate salt tolerance. Swamp dogwood is distributed throughout most of the southeast United States. For a current distribution map, please consult the Plant Profile page for this species on the PLANTS Website. Establishment Like most dogwoods, this species can be grown easily from seeds collected from mature, native trees and from softwood cuttings. Seeds at maturity must be either planted immediately or prechilled. Seeds sown in nursery beds should be covered with ¼ to ½ inch of soil and mulched during the winter. Management Plant in moist soils in full sun to partial shade as it is tolerant to wet and/or low fertility soils. It requires little maintenance in naturalized settings. When used for massing, pruning to within a few inches of the ground every few years promotes fullness. Pests and Potential Problems This plant has no serious insects and diseases except occasional infestation by scale insects and leaf spot. Cultivars, Improved, and Selected Materials (and area of origin) None recommended. Plants are not readily available from nurseries.

Leaf is dark green and shiny above; light green and hairy beneath. Bark: Brownish-gray and rough; with large irregular plates or ridges. Acorns: Up to 1-inch in diameter; almost entirely enclosed in a deep, unfringed cup. Restricted to southeast bottomlands and a few localities in east-central Missouri. 27 Post Oak http://mdc.mo.gov/forest/IandE/oak_hickory/w_oak.htm http://mdc.mo.gov/nathis/plantpage/flora/motrees/p20.htm (Quercus stellata) - Grows in dry and rocky upland woods, to 60 feet tall. Characteristics similar to white oak. Although it is found in nearly every county of the state, it is most common in the Ozarks. Leaves: Usually with five lobes, two of which, above the middle of the leaf, are broad, forming a cross with the axis of the leaf. These and the top lobe are normally slightly indented. Bark: Light brown; divided by deep fissures and scaly ridges. Acorns: Small to 3/4-inch long, the cup overs one-third to one-half of the nut. The name post oak indicates that the wood used to made into fence posts. The Latin Stellata means "star," referring to the starlike tufts of hair on the surfaces of the leaf. SAWMILL MEN GROUP POST OAK with other white oaks in the manufacture of lumber since the wood properties are similar. Woods fires scar the trunks or trees, exposing live wood. This makes an easy opening for decay to hollow the center of wounded trees. As a result of this decay final gross board-foot volume is reduced. Probably the key identifying feature of post oak is its cross-shaped leaf. Being alternate and simple, it usually has five lobes, is shiny green and fuzzy yellow below. The acorn is 3/4 inch log and 1/2 inch wide. It is enclosed for about one-third of its length in a bowl-shaped cup. Forest wildlife such as the gray and fox squirrel, raccoon, quail, deer, wild turkey and ruffed grouse make this acorn a part of their diet. Twigs are moderately stout, orange-tan in color. They are wooly at first, darker and smooth later. The buds are globe to egg-shaped and wooly. The bark is light brown and divided by deep furrows and scaly ridges. Found in almost every county in the state, post oak seldom exceeds 60 feet in height. Many poor timber growing areas support stands of post and blackjack oak. Under average conditions post oak is a very slow growing tree. Post oak wood is used for the same purposes as white oak except for stave bolts because of defects. 28 Dwarf Chestnut Oak http://mdc.mo.gov/forest/IandE/oak_hickory/w_oak.htm (Quercus prinoides) - (also know as dwarf chinkapin or scrub oak).

Bark: Brownish-gray becoming rough or scaly on older wood. Acorns: About ½-inch in diameter with small, warty scales on cup. This is the shortest of Missouri's oaks, and it can produce abundant acorns although only 3 to 10 feet tall 29 Pin Oak http://mdc.mo.gov/forest/IandE/oak_hickory/r_oak.htm http://www.mdc.mo.gov/forest/IandE/MOConservationTreesAndShrubs/pinoak.html (Quercus Palustris) - Under natural conditions a medium-size tree—50- to 70-feet tall—moist valleys, along streams, ponds and swamps, but also sometimes on dry locations. The lower branches spread downward, covering a large area. Pin oak grows faster than other oak species and has become a much planted ornamental. Grows throughout most of Missouri, but absent from the Ozark Plateau and southwestern counties. Many specimens provide good fall coloration. Palustris, Latin, "marshy."

Bark - thin, smooth gray bark on young trees; older bark shallowly fissured Associated species - pecan, bur oak, river birch, cottonwood, sweetgum Ideal site conditions - wet soil, full sun Value to man - landscaping, wood products, windbreaks Value to wildlife - food, cover, dens Growth Rate - fast Range 30 Nuttall Oak http://www.mdc.mo.gov/forest/IandE/MOConservationTreesAndShrubs/nuttalloak.html Quercus texana Nuttall oak was not recognized as a separate species until 1927. It grows on the poorly drained clay flats and low bottoms of the Bootheel. Its leaves and bark are similar to pin oak, a tree it is easily confused with. Nuttall oak may be distinguished from pin oak by its more elongated acorn. Identifying Characteristics Height 95 ft Spread 80 ft Leaves alternate, simple, 4" - 8" long; deeply divided into 5-7 narrow long-pointed lobes ending in a few bristle-tipped teeth; wide sinuses between lobes Flowers male flowers in yellow-green catkins; female flowers inconspicuous Fruit acorn, 3/4" - 1 l/4" long, oblong, usually dark-striped; 1/4 - l/2 enclosed by a deep thick cup Bark gray and smooth; becoming dark and furrowed into flat, scaly ridges Associated species green ash, sweetgum, baldcypress, bur oak, silver maple Ideal site conditions wet soil, full sun Value to man landscaping, wood products, windbreaks Value to wildlife food, cover, dens Growth Rate fast Range 31 Willow Oak http://mdc.mo.gov/forest/IandE/oak_hickory/r_oak.htm (Quercus phellos) A medium-size oak, to 75 feet tall, growing on poorly drained soils and swampy woods. Restricted to southeast Missouri. May do well when planted as ornamental throughout Missouri. Leaves: Narrow, lance-shaped, willowlike; much narrower than the similar shingle-oak leaves, light green above with a pointed tip. Bark: Smooth and gray on young trees; later becoming darker and breaking into thick rough ridges separated by irregular fissures. Acorns: Small, only one-half-inch long, pale brownish-yellow, with striped nuts. The bitter nuts are important food for ducks. Phellos, Greek, means "cork" 32 Cherrybark Oak http://www.mdc.mo.gov/forest/IandE/MOConservationTreesAndShrubs/cherrybarkoak.html Quercus pagoda Cherrybark oak is found in the bottomland forests of southeast Missouri. It prefers rich, well-drained bottomland soils. It is among the largest of the southern oaks and its wood is rated superior to any of the other oaks in the South.
