Cornus rugosa, commonly called roundleaf dogwood, is a deciduous tree native to northern parts of the eastern and central United States and southern parts of central and eastern Canada. [2] [3]
Cornus rugosa is a shrub or small tree, 1–4 m (3–13 ft) tall, with yellowish-green twigs that may have red or purple blotches. Pith is white. Leafs are oppositely arranged, round orbicularly shaped with an acuminate tip, have an entire margin, and are woolly to hairless below. [4] Leaves have 6-8 pairs of lateral veins and 7–15 cm long. Leaf scars are broadly U-shaped with 3 bundle scars.
White flowers appear in early summer arranged on flat topped cymes. The flowers themselves are pedunculate with 4 calyx lobes and 4 petals. The cymes are 3–6 cm (1 1⁄4–2 1⁄4 in) wide and contain 20–50 flowers. Fruits are blue to greenish white drupe that matures in October. [5] [6]
Roundleaf dogwood prefers well drained to normal moisture soil and, like most dogwoods, is shade tolerant. [7]
Roundleaf dogwood is a host species for the spring azure and gossamer wings. [7]
Fruits are eaten by ruffed grouse and sharp-tailed grouse. Twigs are consumed by white tailed deer, Eastern cottontail, and mice. [4]
Roundleaf dogwood is listed as endangered in Maryland and is a species of special concern in Rhode island [2]
Cornus florida, the flowering dogwood, is a species of flowering tree in the family Cornaceae native to eastern North America and northern Mexico. An endemic population once spanned from southernmost coastal Maine south to northern Florida and west to the Mississippi River. The tree is commonly planted as an ornamental in residential and public areas because of its showy bracts and interesting bark structure.
Ptelea trifoliata, commonly known as common hoptree, wafer ash, stinking ash, and skunk bush, is a species of flowering plant in the citrus family (Rutaceae). It is native to North America, where it is found in Canada, Mexico, and the United States. It is a deciduous shrub or tree, with alternate, trifoliate leaves.
Cornus is a genus of about 30–60 species of woody plants in the family Cornaceae, commonly known as dogwoods, which can generally be distinguished by their blossoms, berries, and distinctive bark. Most are deciduous trees or shrubs, but a few species are nearly herbaceous perennial subshrubs, and a few of the woody species are evergreen. Several species have small heads of inconspicuous flowers surrounded by an involucre of large, typically white petal-like bracts, while others have more open clusters of petal-bearing flowers. The various species of dogwood are native throughout much of temperate and boreal Eurasia and North America, with China, Japan, and the southeastern United States being particularly rich in native species.
Rhamnus is a genus of about 110 accepted species of shrubs or small trees, commonly known as buckthorns, in the family Rhamnaceae. Its species range from 1 to 10 m tall and are native mainly in east Asia and North America, but found throughout the temperate and subtropical Northern Hemisphere, and also more locally in the subtropical Southern Hemisphere in parts of Africa and South America. One species, the common buckthorn, was able to flourish as an invasive plant in parts of Canada and the U.S.
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.
Cornus kousa is a small deciduous tree 8–12 m (26–39 ft) tall, in the flowering plant family Cornaceae. Common names include kousa, kousa dogwood, Chinese dogwood, Korean dogwood, and Japanese dogwood. Synonyms are Benthamia kousa and Cynoxylon kousa. It is a plant native to East Asia including Korea, China and Japan. Widely cultivated as an ornamental, it is naturalized in New York State.
Cornus nuttallii, the Pacific dogwood or mountain dogwood, is a species of dogwood native to western North America from the lowlands of southern British Columbia to the mountains of southern California, with an inland population in central Idaho. Cultivated examples are found as far north as Haida Gwaii. It is a small to medium-sized deciduous tree, reaching 10–25 m tall.
Cornus walteri, also called Walter's dogwood, is a deciduous shrub or small tree 8–16 m tall, native to eastern Asia in Korea and much of China from Liaoning to Yunnan.
Cornus canadensis is a species of flowering plant in the dogwood family, native to eastern Asia, the northern United States, Colorado, New Mexico, Canada and Greenland. Unlike its relatives, which are for the most part substantial trees and shrubs, C. canadensis is a creeping, rhizomatous perennial growing to about 20 cm (8 in) tall.
Cornus racemosa, the northern swamp dogwood, gray dogwood or panicle dogwood, is a shrubby plant native to southeastern Canada and the northeastern United States. It is a member of the dogwood genus Cornus and the family Cornaceae.
Lindera benzoin is a shrub in the laurel family, native to eastern North America, ranging from Maine and New York to Ontario in the north, and to Kansas, Texas, and northern Florida in the center and south. Within its native range it is a relatively common plant where it grows in the understory in moist, rich woods, especially those with exposed limestone.
Cornus sericea, syn. C. stolonifera, Swida sericea, red osier or red-osier dogwood, is a species of flowering plant in the family Cornaceae, native throughout northern and western North America from Alaska east to Newfoundland, south to Durango and Nuevo León in the west, and Illinois and Virginia in the east. It has sometimes been considered a synonym of the Asian species Cornus alba. Other names include red brush, red willow, redstem dogwood, redtwig dogwood, red-rood, American dogwood, creek dogwood, and western dogwood.
Cornus sanguinea, the common dogwood or bloody dogwood, is a species of dogwood native to most of Europe and western Asia, from England and central Scotland east to the Caspian Sea. It is widely grown as an ornamental plant.
Cornus mas, the Cornelian cherry, European cornel or Cornelian cherry dogwood, is a species of flowering plant in the dogwood family Cornaceae, native to Southern Europe and Southwestern Asia.
Cornus alternifolia is a species of flowering plant in the dogwood family Cornaceae, native to eastern North America, from Newfoundland west to southern Manitoba and Minnesota, and south to northern Florida and Mississippi. It is rare in the southern United States. It is commonly known as green osier, alternate-leaved dogwood, and pagoda dogwood.
Elaeagnus commutata, the silverberry or wolf-willow, is a species of Elaeagnus native to western and boreal North America, from southern Alaska through British Columbia east to Quebec, south to Utah, and across the upper Midwestern United States to South Dakota and western Minnesota. It typically grows on dry to moist sandy and gravel soils in steppes, meadows or woodland edges.

Symplocos tinctoria is a deciduous or evergreen shrub or tree. It is recognized by pith of twigs chambered; by foliage not notably aromatic when bruised, leaves finely hairy beneath. Shrubs or trees to 17 m tall by 36 cm DBH. The largest first-year twigs are under 3 mm across, terminal buds with acute tip, scales ciliate. Leaves are 7–15 cm long, margin entire or occasionally some teeth on the apical half, with a sweet taste that may be faint in old leaves. It is conspicuous when in flower; flowers opening before new leaves develop, fragrant, in clusters from axils of previous year's leaves or from just above the leaf scars if the leaves have fallen; the petals are creamy yellow to yellow, with one pistil. Fruits nearly cylindrical to ellipsoid drupes 8–12 mm long, with thin pulp and a hard stone containing 1 seed; the tip usually retaining parts of the sepals. Foliage is relished by browsing wildlife. A yellow dye may be obtained from bark and leaves. It flowers Mar to May.
Cornus controversa, syn. Swida controversa, is a species of flowering plant in the genus Cornus of the dogwood family Cornaceae, native to China, Korea, the Himalayas and Japan. It is a deciduous tree growing to 50 ft (15 m), with multiple tiered branches. Flat panicles of white flowers appear in summer, followed by globose black fruit. Ovate dark green leaves are glaucous underneath and turn red-purple in autumn. It is cultivated in gardens and parks in temperate regions.
