Description
In the wild, it most commonly grows in areas of rich, poorly drained soils, such as riparian zones and wetlands
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The ...
, or in upland areas which receive more than 20 inches of precipitation annually. 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 10,000 feet (3,000m), but in many areas is most common above 1,500 feet.
It is a medium to tall deciduous
In the fields of horticulture and Botany, the term ''deciduous'' () means "falling off at maturity" and "tending to fall off", in reference to trees and shrubs that seasonally shed leaves, usually in the autumn; to the shedding of petals, aft ...

Ecology
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
Ungulates ( ) are members of the diverse clade Ungulata which primarily consists of large mammals with hooves. These include odd-toed ungulates such as horses, rhinoceroses, and tapirs; and even-toed ungulates such as cattle, pigs, giraffes, cam ...
; 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.
''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.
Although its conservation status is overall secure, it is considered vulnerable in Iowa

Uses
''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.
