Redosier Dogwood- Cornus sericea is our native red twigged dogwood. It is most often noticed during the winter months when the cold weather turns the green summer stems a brilliant bright red. These red winter stems are the reason these are seen in landscape plantings. Against a snowy background these red stems really pop and become a focal point in an otherwise dull winter background.
Redosier Dogwood is a 7 to 9′ tall multi stemmed shrub that is hardy in zones 2 to 8. It does not color well in zone 8 . It needs the cold to color well. It blooms in late May and Early June. The flowers are visited by both honeybees and native bees. The flowers themselves are born in flat topped cymes. The cymes are 1 1/2″ to 2 1/2″ wide and are attractive but not as showy as the Flowering Dogwood. In the fall the cymes are filled with white drupes (berries) that are quite showy themselves. As winter progresses the birds will eat the berries.
This Dogwood thrives best in wet areas, marshy ground, areas along streams or in rain gardens. Being a native plant, there are a few insects and diseases that have adapted to this plant. Most cause little damage.
While Dogwoods are not considered important bee trees, honeybees work the flowers of several shrub species of Dogwood like Redosier, Cornus mas, Silky Dogwood and others. The Redosier Dogwood fills two purposes, a good landscape plant that is also a pollinator friendly.
