Cornus sericea, the red osier or red-osier dogwood, [2] is a species of flowering plant in the family Cornaceae, native to much of North America. It has sometimes been considered a synonym of the Asian species Cornus alba . Other names include red brush, red willow, [3] [4] [5] redstem dogwood, [3] [5] redtwig dogwood, red-rood, American dogwood, [3] creek dogwood, and western dogwood. [3]
It is a medium to tall deciduous shrub, growing 1.5–4 metres (5–13 feet) tall and 3–5 m (10–16+1⁄2 ft) wide, spreading readily by underground stolons to form dense thickets. The branches and twigs are dark red, although wild plants may lack this coloration in shaded areas.
The leaves are opposite, 5–12 centimetres (2–4+1⁄2 inches) long and 2.5–6 cm (1–2+1⁄2 in) broad, with an ovate to oblong shape and an entire margin; they are dark green above and glaucous below; fall color is commonly bright red to purple. Like all dogwoods, they have characteristic stringy white piths within the leaf stalks, which can be used for identification. [6]
The flowers are 5–10 millimetres (1⁄4–3⁄8 in) wide, flat, umbel-like and dull white, in clusters 3–6 cm across.
It is a variable species, with two subspecies commonly accepted:
The Latin specific epithet sericea means "silky", referring to the texture of the leaves. [7]
It is native throughout boreal and temperate zones in 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.
Cornus sericea L. has been recorded from counties Antrim and Londonderry in Northern Ireland. [8]
In the wild, the species most commonly grows in areas of rich, poorly drained soils, such as riparian zones and wetlands, or in upland areas which receive more than 510 mm (20 in) of annual precipitation. More uncommonly, it may be found in drier zones albeit at lesser abundance. Red osier dogwood is tolerant of flooding and has been known to survive up to seven years of water above root crown level. It occurs from sea level to 3,000 m (10,000 ft), but in many areas is most common above 460 m (1,500 ft). [9]
Red osier dogwood provides food and cover for many species of mammals and birds. The stems and especially new shoots are browsed by moose, elk, bighorn sheep, mountain goats, beavers, and rabbits, while the fruits are an important autumn food source for bears, small mammals, and 47 different bird species. In winter, red osier dogwood is heavily browsed by ungulates; in some areas use exceeds availability and individuals which have not been browsed are rare. The shrub is also important for nesting habitat and cover for a great variety of animals. [9]
Cornus sericea is shade tolerant but prefers intermediate to high light levels. It tolerates disturbance well, and appears early in both primary and secondary succession throughout its native range, but especially in floodplains and riparian zones. It thrives in fire-disturbed sites, sprouting from seeds or damaged shrubs. [9]
Although its conservation status is overall secure, it is considered vulnerable in Iowa and critically imperiled in Kentucky and Virginia. [1]
Cornus sericea is a popular ornamental shrub that is often planted for the red coloring of its twigs in the dormant season. The cultivars 'Bud's Yellow', [10] 'Flaviramea' [11] with lime green stems, and 'Hedgerows Gold' [12] (variegated foliage) have gained the Royal Horticultural Society's Award of Garden Merit (confirmed in 2017). [13]
Like most dogwood species native to North America, C. sericea can be parasitized by the dogwood sawfly, possibly leaving much of the plant devoid of leaves. A variety of pesticides are effective; however, hand-picking the larvae is also an option.[ citation needed ]
Cornus sericea is frequently used for waterway bank erosion protection and restoration in the United States and Canada. Its root system provides excellent soil retention, it is hardy and provides an attractive shrub even when bare in winter, and its ability to be reproduced by cuttings makes it a low-cost solution for large-scale plantings. [14] [15]
Some Plateau Indigenous tribes ate the berries to treat colds and to slow bleeding. [16] [17]
Known as čhaŋšáša in Lakota, the inner bark was also used by the Lakota and other Native Americans as "traditional tobacco", either by itself or in a mixture with other plant materials. [18] [19] Among the Algonquian peoples such as the Ojibwe, the smoking mixtures, known as kinnikinnick, blended the inner bark with tobacco, [4] while more western tribes added it to the bearberry leaf to improve the taste. [16] [20]
The Ojibwe used red-osier dogwood bark as a dye by taking the inner bark and mixing it with other plants or minerals. [3]
The withies, or osiers, are used in basketry.
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 or cornels, 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 some 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.
Cercis canadensis, the eastern redbud, is a large deciduous shrub or small tree, native to eastern North America from southern Michigan south to central Mexico, west to New Mexico. Species thrive as far west as California and as far north as southern Ontario. It is the state tree of Oklahoma. The prevalence of the so-called "Columbus strain" has seen the residents of Columbus, Wisconsin, embrace the plant in their city's identity. Known as the "Redbud City," the town hosts "Redbud Day" annually the Saturday before Mother's Day, organizing a variety of themed events to recognize the tree.
Bearberries are three species of dwarf shrubs in the genus Arctostaphylos. Unlike the other species of Arctostaphylos, they are adapted to Arctic and subarctic climates, and have a circumpolar distribution in northern North America, Asia and Europe.

It is rare in the southern United States. It is commonly known as green osier, alternate-leaved dogwood, and pagoda dogwood.
Cornus alba, the red-barked, white or Siberian dogwood, is a species of flowering plant in the family Cornaceae, native to Siberia, northern China and Korea. It is a large deciduous surculose (suckering) shrub that can be grown as a small tree. As a popular ornamental used in landscaping its notable features include the red stems in fall (autumn) through late winter, bright winter bark; and the variegated foliage in some cultivars, such as C. alba 'Elegantissima'. C. alba can grow to 3 m (10 ft) high, but variegated forms are less vigorous. For the brightest winter bark, young shoots are encouraged by cutting to the ground some older stems at the end of the winter, before leaves are open. The oval fruits are white, sometimes tinted blue.
