Silky Dogwood (Cornus amomum) is a hardy, moisture-loving native shrub that provides multi-season interest and essential habitat value. With its showy clusters of creamy white flowers, attractive bluish fruit, and deep red stems in winter, it serves as both a landscape workhorse and a striking ornamental in naturalistic plantings.
Distinctive Features
This multi-stemmed deciduous shrub grows 6 to 10 feet tall and wide, forming a dense thicket over time. Soft green leaves turn reddish-purple in fall, while flat-topped white flower clusters bloom in late spring to early summer. These are followed by striking blue drupes that ripen in late summer and are quickly consumed by birds. In winter, the stems reveal a reddish to purplish hue, adding off-season color and structure.
