Chionanthus virginicus[3] (white fringetree) is a tree native to the savannas and lowlands of the northeastern and southeastern United States, from Massachusetts south to Florida, and west to Oklahoma and Texas.
It is a deciduous shrub or small tree growing to as much as 10 to 11 metres (33 to 36 ft) tall, though ordinarily less. The bark is scaly, brown tinged with red. The shoots are light green, downy at first, later becoming light brown or orange. The buds are light brown, ovate, acute, 3 millimetres (0.12 in) long. The leaves are opposite, simple, ovate or oblong, 7.5 to 20 centimetres (3.0 to 7.9 in) long and 2.5 to 10 centimetres (0.98 to 3.94 in) broad, with a petiole 2 centimetres (0.79 in) long, and an entire margin; they are hairless above, and finely downy below, particularly along the veins, and turn yellow in fall. The richly-scented[6] flowers have a pure white, deeply four-lobed corolla, the lobes thread-like, 1.5 to 2.5 centimetres (0.59 to 0.98 in) long and 3 millimetres (0.12 in) broad; they are produced in drooping axillary panicles 10 to 25 centimetres (3.9 to 9.8 in) long when the leaves are half grown, in mid- to late May in New York City, earlier in the south.
It is usually dioecious, though occasional plants bear flowers of both sexes. The fruit is an ovoid dark blue to purple drupe 1.5 to 2 centimetres (0.59 to 0.79 in) long, containing a single seed (rarely two or three), mature in late summer to mid fall
Juglans nigra, the eastern American black walnut, is a species of deciduous tree in the walnut family, Juglandaceae, native to North America. It grows mostly in riparian zones, from southern Ontario, west to southeast South Dakota, south to Georgia, northern Florida and southwest to central Texas. Wild trees in the upper Ottawa Valley may be an isolated native population or may have derived from planted trees.
Black walnut is an important tree commercially, as the wood is a deep brown color and easily worked. Walnut seeds (nuts) are cultivated for their distinctive and desirable taste. Walnut trees are grown both for lumber and food, and many cultivars have been developed for improved quality wood or nuts. Black walnut is susceptible to thousand cankers disease, which provoked a decline of walnut trees in some regions.
Juniperus virginiana is a dense slow-growing coniferous evergreen tree with a conical or subcylindrical shaped crown[8] that may never become more than a bush on poor soil, but is ordinarily from 5–20 metres (16–66 feet) tall, with a short trunk 30–100 centimetres (12–39 inches) in diameter, rarely to 27 m (89 ft) in height and 170 cm (67 in) in diameter. The oldest tree reported, from West Virginia, was 940 years old.[9] The bark is reddish-brown, fibrous, and peels off in narrow strips. The leaves are of two types; sharp, spreading needle-like juvenile leaves 5–10 millimetres (3⁄16–3⁄8 in) long, and tightly adpressed scale-like adult leaves 2–4 mm (1⁄16–3⁄16 in) long; they are arranged in opposite decussate pairs or occasionally whorls of three. The juvenile leaves are found on young plants up to 3 years old, and as scattered shoots on adult trees, usually in shade. The seed cones are 3–7 mm (1⁄8–1⁄4 in) long, berry-like, dark purple-blue with a white wax cover giving an overall sky-blue color (though the wax often rubs off); they contain one to three (rarely up to four) seeds, and are mature in 6–8 months from pollination. The juniper berry is an important winter food for many birds, which disperse the wingless seeds. The pollen cones are 2–3 mm (1⁄16–1⁄8 in) long and 1.5 mm (1⁄16 in) broad, shedding pollen in late winter or early spring. The trees are usually dioecious, with pollen and seed cones on separate trees,[5][6][7] yet some are monoecious.

Quercus alba, the White Oak, is one of the preeminent hardwoods of eastern and central North America. It is a long-lived oak, native to eastern and central North America and found from Minnesota, Ontario, Quebec, and southern Maine south as far as northern Florida and eastern Texas.
Specimens have been documented to be over 450 years old. Although called a white oak, it is very unusual to find an individual specimen with white bark; the usual colour is a light gray. The name comes from the colour of the finished wood. In the forest it can reach a magnificent height and in the open it develops into a massive broad-topped tree with large branches striking out at wide angles.
Quercus alba typically reaches heights of 24 to 30 metres (80–100 feet) at maturity, and its canopy can become quite massive as its lower branches are apt to extend far out laterally, parallel to the ground. Trees growing in a forest will become much taller than ones in an open area which develop to be short and massive. Read More
Quercus Bicolor, the Swamp White Oak, is a North American species of medium-sized trees in the beech family. It is a common element of America's north central and northeastern mixed forests. It can survive in a variety of habitats. It forms hybrids with bur oak where they occur together in the wild.
Quercus bicolor grows rapidly and can reach 18 to 24 meters (60 to 80 feet) tall with the tallest known reaching 29 m (95 ft) and lives up to 285 years. The bark resembles that of the white oak. The leaves are broad ovoid, 12–18 centimetres (4+3⁄4–7 inches) long and 7–11 cm (2+3⁄4–4+1⁄4 in) 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 the white oak can be. Read More
Quercus Coccinea, the Scarlet Oak, is a deciduous tree in the red oak section Lobatae of the genus Quercus, in the family Fagaceae.
It is primarily distributed in the central and eastern United States. It occurs on dry, sandy, usually acidic soil. It is often an important canopy species in oak–heath forests. The scarlet oak is the official tree of Washington, D.C.
Quercus coccinea is a medium to large deciduous tree growing to around 5.5–7.3 metres (18–24 feet) with an open, rounded crown; the maximum height is approximately 30 m (100 ft). The trunk diameter at breast height is typically 61 to 91 centimetres (24 to 36 inches) It is a medium-size tree that grows fast and matures relatively early. It sets a deep growing taproot.
The leaves are glossy green, 7–17 cm (2+3⁄4–6+3⁄4 in) long and 8–13 cm (3+1⁄4–5 in) broad, with seven lobes, and deep sinuses between the lobes. Each lobe has 3–7 bristle-tipped teeth. The leaf is hairless (unlike the related pin oak (Q. palustris), with tufts of pale orange-brown down where the lobe veins join the central vein). The foliage generally becomes bright scarlet in autumn. The flower color is yellow to green, depending on the season.

Quercus Macrocarpa, the Bur Aak or Burr Oak, is a species of oak tree native to eastern North America. It is in the white oak section, Quercus sect. Quercus, and is also called mossycup oak, mossycup white oak, blue oak, or scrub oak. The acorns are the largest of any North American oak (thus the species name macrocarpa, from Ancient Greek μακρός makrós "large" and καρπός karpós "fruit"), and are important food for wildlife.
Quercus macrocarpa is a large deciduous tree growing up to 30 metres (98 feet), rarely 50 m (160 ft), in height, and is one of the most massive oaks with a trunk diameter of up to 3 m (10 ft). It is one of the slowest-growing oaks, with a growth rate of 30 centimetres (12 in) per year when young. However, one source states that a well-established tree can grow up to 51 cm (20 in) per year. A 20-year-old tree will be about 18 m (60 ft) tall if grown in full sun. Naturally occurring saplings in forests will typically be older. Bur oaks commonly get to be 200 to 300 years old, and may live up to 400 years. The bark is gray with distinct vertical ridges.

Quercus montana, the chestnut oak, is a species of oak in the white oak group, Quercus sect. Quercus. It is native to the eastern United States, where it is one of the most important ridgetop trees from southern Maine southwest to central Mississippi, with an outlying northwestern population in southern Michigan. It is also sometimes called rock oak because of its presence in montane and other rocky habitats.
As a consequence of its dry habitat and ridgetop exposure, Quercus montana is not usually a large tree, typically growing to 18–22 metres (59–72 feet) tall; specimens growing in better conditions can grow up to 40–43 m (131–141 ft) tall. They tend to have a similar spread of 18–22 m (59–72 ft). A 10-year-old sapling grown in full sun will stand about 5 m (16 ft) tall. This species is often an important canopy species in an oak-heath forest.

This 75-100 ft., deciduous oak occasionally reaches 120 ft. in height. Its straight trunk is clear of branches for some distance above the ground and supports a wide canopy, commonly 3/4 that of height. The dark bark is striped with long, smooth plates separated by deep furrows. Leaf lobes are bristle-tipped. Fall color is can be crimson, golden-orange, or russet. The northernmost eastern oak, it is also the most important lumber species of red oak.
A popular handsome shade and street tree, with good form and dense foliage. One of the most rapid-growing oaks, it transplants easily, is hardy in city conditions, and endures cold.
In the northern part of its range, Quercus velutina is a relatively small tree, reaching a height of 20–25 metres (66–82 feet) and a diameter of 90 centimetres (35 inches), but it grows larger in the south and center of its range, where heights of up to 42 m (138 ft) are known.
The leaves of the black oak are alternately arranged on the twig and are 10–20 cm (4–8 in) long with 5–7 bristle-tipped lobes separated by deep U-shaped notches. The upper surface of the leaf is a shiny deep green, and the lower is yellowish-brown. There are also stellate hairs on the underside of the leaf that grow in clumps.[5] Some key characteristics for identification include that leaves grown in the sun have very deep U-shaped sinuses and that the buds are velvety and covered in white hairs.

The American elm is a deciduous tree which, under ideal conditions, can grow to heights of 21 to 35 meters (69 to 115 feet). The trunk may have a diameter at breast height (dbh) of more than 1.2 m (4 ft), supporting a high, spreading umbrella-like canopy. The leaves are alternate, 7–20 centimeters (3–8 inches) long, with double-serrate margins and an oblique base. The leaves turn yellow in the fall. The perfect flowers are small, purple-brown and, being wind-pollinated, apetalous. The flowers are also protogynous, the female parts maturing before the male, thus reducing, but not eliminating, self-fertilization, and emerge in early spring before the leaves. The fruit is a flat samara 2 cm (3⁄4 in) long by 1.5 cm broad, with a circular papery wing surrounding the single 4.5 millimeters (1⁄8 inch) seed. As in the closely related Ulmus laevis (European white elm), 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.

Green giant arborvitae is a large, needled, evergreen conifer tree. This tree is a hybrid cultivar of T. plicata and T. standishii. This hybrid was introduced to the U.S. in 1967 when the National Arboretum received a specimen. Once available to nurseries, homeowners became interested to use this tree in their landscapes. Dark green scale-like needles retain their deep green color through the winter. A mature height ranges from 40-60 feet along with a width of 12-18 feet. This tree can live from 40 to 60 years. It thrives in a moist, full-sun environment with little shade in the afternoon. Ideally, you will find 3-4 feet of growth per year. It is resistant to most diseases, insects, drought, and deer. This tree is not salt tolerant. Minimal landscaping is necessary to keep its shape due to its growth pattern and hardiness.
