Red-Osier Dogwood

Growing Conditions

Growing Zones

Thrives in USDA Zones 2 - 8

Companion Planting

When to Plant

• Transplant

  Plant bare-root or container shrubs in spring or autumn in moist soil; root suckers transplant easily in early spring

• Harvest

  Cut stem branches in December - February for indoor arrangements; vigorous re-pruning stimulates bright new stem growth each season

Organic Growing Tips

• To maintain the brightest stem colour, cut one-third of the oldest stems to the ground each late winter or early spring; new growth produces the most vivid red.

• Mass plant along stream banks or drainage ditches for effective erosion control; roots knit together quickly and tolerate flooding.

• The white berries are especially valuable to migratory songbirds in late summer and early autumn; site where birds can land safely.

• Dogwood borers are the most serious pest; look for D-shaped exit holes in older stems. Regular rejuvenation pruning and avoiding mechanical stem damage minimizes infestations.

• Tolerates urban conditions including compacted, wet soils and road salt better than most ornamental shrubs.

Common Pests

• Dogwood Borer
• Cottony Scale
• Leaf Spot
• Powdery Mildew

Natural History

Cornus sericea, the red-osier dogwood (also known as red-twig dogwood, formerly Cornus stolonifera), is one of the most ecologically significant and widely distributed native shrubs on the North American continent. Its native range extends from Alaska across Canada and south through virtually the entire continental United States, making it one of the broadest-ranging woody plants in North America. The species name sericea (Latin: silky) refers to the soft hairs on the leaves. The common name "osier" is borrowed from European basket-making tradition, where osier refers to flexible young willow rods used for weaving; the red-osier dogwood's young stems were similarly used by Indigenous peoples for basket weaving, with the bright red stems making particularly sought-after material. The ecological role of red-osier dogwood in riparian ecosystems is profound: it is among the first woody plants to colonize stream banks after disturbance, its roots bind and stabilize soil against erosion, and the fruits - produced in late summer after the early berry season has ended - provide critical nutrition for migratory songbirds, grouse, bears, and other wildlife during autumn. Beavers heavily use red-osier dogwood for dam-building material and as a food source. The flat-topped white flower clusters support an extraordinary diversity of small native pollinators including native bees, wasps, flies, and beetles in early summer.

Traditional Use

Red-osier dogwood bark and roots were used extensively by Indigenous peoples of North America as a medicinal plant, primarily as a general tonic, digestive remedy, and ceremonial smoking mixture. The inner bark (scraped from young stems) and the root bark were the primary plant parts used medicinally and in the sacred tobacco-substitute mixture called kinnikinnick.

• Ojibwe, Cree, and Great Lakes Indigenous peoples - Inner bark and root bark

  Ethnobotanical records from the Ojibwe, Cree, Menominee, and other Great Lakes peoples document extensive use of red-osier dogwood. The inner bark scraped from young stems was a key component of kinnikinnick, a ceremonial and social smoking mixture used across many nations from the Great Plains to the Northeast. Medicinally, bark decoctions were taken for fevers, colds, stomach complaints, and as a general tonic. Root bark preparations were used for pain and as a mild astringent.

• Plains and western Indigenous peoples - Inner bark, stems

  On the Great Plains and in the western mountain regions, red-osier dogwood stems and inner bark were used for kinnikinnick smoking mixtures and as a fire-starting material. The Blackfoot, Sioux, and other Plains nations used the plant in this context. Stem bark was used in willow-bark-like applications for fever and pain among some Pacific Northwest peoples.

• Early American botanical medicine - Bark

  Early American botanical physicians noted that Indigenous peoples used dogwood bark as a quinine substitute for malarial fever, primarily in the context of Cornus florida (flowering dogwood). Cornus sericea was similarly noted in some botanical accounts as a mild tonic and astringent, though it was less prominent in formal botanical medicine than its eastern relative.

The inner bark and berries of red-osier dogwood are not considered dangerously toxic, but the berries are mildly bitter and not palatable raw in significant quantities; they are primarily of value as wildlife food. Internal medicinal use of the bark is not recommended without guidance from an experienced herbalist. The kinnikinnick smoking mixture tradition belongs to specific Indigenous ceremonial contexts.

Morphology (Plant Structure & Identification)

• Root System

  Vigorous, spreading, suckering root system that produces abundant root suckers, forming thickets over time; highly effective for stream bank stabilization; tolerates flooding and saturated soils.

• Stem

  Multi-stemmed, arching shrub 6 - 9 feet tall; new stems are blood-red in winter, fading to green in summer; older stems are gray-brown; the contrast between bright new red stems and older gray stems makes it one of the most ornamentally valuable winter-interest plants.

• Leaves

  Opposite, oval to elliptic, 2 - 4 inches long; dark green above with slightly silky texture, paler below; veins arc toward the leaf tip; autumn colour is reddish-purple, adding to the multi-season ornamental value.

• Flowers

  Flat-topped corymbs 1.5 - 2.5 inches across of many small white 4-petalled flowers; produced in May - June; mildly fragrant; attractive to a wide range of small native bees, wasps, and flies.

• Fruit

  Small, round, white to slightly bluish-white drupes 0.25 inch across in flat-topped clusters; ripening in August - September; bitter and not palatable to humans; heavily consumed by birds during autumn migration.
