Red-osier Dogwood

Red-osier Dogwood

10-5-15 red-osier dogwood IMG_6598Gray Dogwood (also known as Gray-stemmed Dogwood) and Red-osier Dogwood both have white berries, a white pith, and red peduncles, or fruit stems. However, the branches of Gray Dogwood are gray, and those of Red-osier Dogwood are red. Hence, I believe the shrub identified as Red-osier Dogwood in today’s post was actually Gray Dogwood. This correction is thanks to John Gregoire’s keen eyes.

Red-osier & Silky Dogwood Fruits Ripening

10-6-15 silky dogwood 291Some of the most prolific flowering shrubs in the Northeast are dogwoods. In the spring, their flowers attract attention and at this time of year their colorful fruit stands out. There are many species of dogwood, two of which are Red-osier Dogwood (Cornus sericea) and Silky Dogwood (Cornus amomum). These two shrubs can be hard to tell apart, as they both have white flowers, red stems and similar foliage. In the fall, however, the color of their fruit differs, as does their pith, or central stem tissue. The mature berries of Red-osier Dogwood are dull white and its pith is also white. Silky Dogwood’s blue berries have white blotches, and its stem and branches have a salmon-colored pith.

The fruit of these dogwoods and others is an extremely important source of food for many migrating songbirds, as well as resident birds. Wood ducks, Northern Cardinals, Eastern Bluebirds, Gray Catbirds, Purple Finches, Evening Grosbeaks, American Robins, Yellow-bellied Sapsuckers, Wood and Hermit Thrushes, Red-eyed and Warbling Vireos, Cedar Waxwings and Downy Woodpeckers all consume dogwood berries.
