Morphology

Deciduous, multi-stemmed, solitary shrub to 3 m or more; twigs of current year's growth densely puberulent; young twigs often reddish; older twigs streaked with gray; pith of second-year twigs chocolate-brown. Leaves smooth, opposite, oblong, acuminate, deep green above, pale below. Flowers small, in open cymes. Fruits blue, sometimes whitish, produced in late summer.    

Notes

Flowers mid May to mid July

Wetland indicator: Facultative Wetland -

The blue fruits are a good identifying characteristic in late summer. Cornus sericea is similar but lacks the gray streaks on older twigs. Silky threads are apparent if a leaf is broken lengthwise and the pieces slowly pulled apart, however this is true of the leaves of most of the shrubby dogwoods.
