Redosier dogwood

Extension is expanding its online education and resources while in-person events and classes are canceled.

(Cornus sericea) is a shrub native to Minnesota with colorful red or yellow winter bark that provides great winter interest.

As a landscape plant, redosier dogwood is extremely versatile.

It can be used as an accent, specimen or key plant, and in groups and large masses for borders and screens.

Redosier dogwood is also used in plantings for wildlife as its berries attract and are eaten by birds and mammals.

Because of its native status, soil adaptability and tolerance of flooding and wet soils, redosier dogwood is also used along shorelines and in rain gardens.

Pruning to maintain color

A fruit cluster consisting of numerous small white round fruit with red fall leaves on Isanti dogwood — Fruit and fall color on ‘Isanti’ dogwood

In late summer, younger stems turn to red or yellow-green and color intensifies throughout winter.

The brightly-colored bark occurs on stems that are less than 3 years old, so rejuvenation pruning should be a regular practice.

Remove the oldest third of stems down to the base of the plant every year or two to promote growth of the younger, colorful stems.
