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.

4-8-13 red-osier dogwood IMG_8874Red-osier dogwood (Cornus sericea), as its name implies, lends color to wetlands year-round, but it really comes into its own at this time of year.  In early spring this shrub is especially noticeable, as its red bark becomes much more vivid due to anthocyanin pigments which are affected by light intensity.  Although it can tolerate light shading, the stems and branches in shaded sites tend to be greener.  Native Americans utilized every part of this shrub,especially the stems and shoots.  Inner bark was used in tobacco mixtures during the sacred pipe ceremony, branches and shoots were made into baskets, dreamcatchers, bows and arrows, and peeled twigs were used as toothbrushes for their whitening effect on teeth.
