Acer saccharum, the sugar maple, is a species of flowering plant in the soapberry and lychee family Sapindaceae. It is native to the hardwood forests of eastern Canada and the eastern United States. Sugar maple is best known for being the primary source of maple syrup and for its brightly colored autumn foliage. It may also be called "rock maple," "sugar tree," "sweet maple," or, particularly in reference to the wood, "hard maple," "birds-eye maple," or "curly maple," the last two being specially figured lumber.

Betula papyrifera (paper birch, also known as (American) white birch and canoe birch) is a short-lived species of birch native to northern North America. Paper birch is named after the tree's thin white bark, which often peels in paper-like layers from the trunk. Paper birch is often one of the first species to colonize a burned area within the northern latitudes, and is an important species for moose browsing. Primary commercial uses for paper birch wood are as boltwood and sawlogs, while secondary products include firewood and pulpwood. It is the provincial tree of Saskatchewan and the

Fraxinus pennsylvanica, the green ash or red ash, is a species of ash native to eastern and central North America, from Nova Scotia west to southeastern Alberta and eastern Colorado, south to northern Florida, and southwest to Oklahoma and eastern Texas. It has spread and become naturalized in much of the western United States and also in Argentina and Europe, from Spain to Russia. Other names more rarely used include downy ash, swamp ash, and water ash.

Franklinia is a monotypic genus in the tea family, Theaceae. The sole species in this genus is a flowering tree, Franklinia alatamaha, commonly called Franklinias or the Franklin tree, and native to the Altamaha River valley in Georgia in the southeastern United States. It has been extinct in the wild since the early 19th century, but survives as a cultivated ornamental tree. In the past, some botanists have included Franklinia within the related genus Gordonia. The southeastern North American species Gordonia lasianthus differs in having evergreen foliage, flowers with longer stems, winged

It is native to eastern North America and is most commonly found in the northeast United States as well as southern Quebec, New Brunswick, and Nova Scotia. The tree is a pioneer species that is commonly found in sites following disturbance, such as fire or logging. Gray birches don't have as much economic value as other birch species but are still commonly used as ornamental trees.

Taxus canadensis, the Canada yew or Canadian yew, is a conifer native to central and eastern North America, thriving in swampy woods, ravines, riverbanks and on lake shores. Locally called simply as "yew", this species is also referred to as American yew or ground-hemlock. Most of its range is well north of the Ohio River. It is, however, found as a rare ice age relict in some coves of the Appalachian Mountains. The southernmost colonies are known from Ashe and Watauga Counties in North Carolina.

Prunus americana, commonly called the American plum, wild plum, or Marshall's large yellow sweet plum, is a species of Prunus native to North America from Saskatchewan and Idaho south to New Mexico and east to Québec, Maine and Florida. Prunus americana has often been planted outside its native range and sometimes escapes cultivation. It is commonly confused with the Canada plum (Prunus nigra), although the fruit is smaller and rounder and bright red as opposed to yellow. Many cultivated varieties have been derived from this species. It forms an excellent stock upon which to graft the

Fraxinus nigra, or the black ash, is a species of ash native to much of eastern Canada and the northeastern United States, from western Newfoundland west to southeastern Manitoba, and south to Illinois and northern Virginia. Formerly abundant, as of 2017 the species is threatened with near total extirpation throughout its range within the next century as a result of infestation by an invasive parasitic insect known as the emerald ash borer (Agrilus planipennis).

The tree species Sorbus americana is commonly known as the American mountain-ash. It is a deciduous perennial tree, native to eastern North America. The American mountain-ash and related species (most often the European mountain-ash, Sorbus aucuparia) are also referred to as rowan trees.

Rosa palustris, the swamp rose, is a shrub in the rose family native to much of eastern North America. It can be found from Nova Scotia and New Brunswick in the north, south to Florida and west to Arkansas and Ontario. It is a host of the blinded sphinx moth and Coptotriche admirabilis.

Prunus maritima, the beach plum, is a species of plum native to the East Coast of the United States. It is a choice wild edible and its few pests and salt tolerance make it a resilient fruit crop for degraded lands and urban soils.

Corylus cornuta, the beaked hazelnut (or just beaked hazel), is a deciduous shrubby hazel with two subspecies found throughout most of North America.

Lonicera canadensis (American fly honeysuckle or Canada fly honeysuckle) is a flowering deciduous, perennial, phanerophytic shrub which is monoclinous and grows 1–2 m (3 ft 3 in – 6 ft 7 in) tall. It typically flowers from the last week of April until the third or fourth week of May. Fruit appears approximately the first week of June until the first week of August. The fruit is fed upon by a variety of avian frugivores including the American robin (Turdus migratorius) and northern cardinal (Cardinalis cardinalis). The seeds can remain viable after being maintained for several years in dry

Nyssa ogeche, commonly referred to as Ogeechee tupelo, white tupelo, river lime, ogeechee lime tree, sour gum or wild lime is a deciduous tree endemic to the southeastern United States. Growing to 15 m (~50 ft), it is in flower from March to May, and the seeds ripen from August to October. The flowers are pollinated by bees. It is noted for attracting wildlife. Ogeechee tupelo requires a very moist site and is distributed along the borders of rivers, swamps, and ponds that are frequently inundated. Ogeechee tupelo prefers slow flowing, low water to standing water. It grows naturally from the

Prunus angustifolia, known commonly as Chickasaw plum, Cherokee plum, Florida sand plum, sandhill plum, or sand plum, is a North American species of plum-bearing tree. It was originally cultivated by Native Americans before the arrival of Europeans. The species' name angustifolia refers to its narrow leaves. It became the official state fruit of Kansas in 2022.

It is native to the eastern United States from Maine south to northern Florida and west to Ohio and eastern Texas. It contains the alkaloid berberine, which has a number of traditional and contemporary uses for dyeing and medicine.
