Cornus amomum

Silky dogwood is a native, medium- to large-sized, deciduous shrub in the dogwood family (Cornaceae). It is native to central and the eastern part of the United States and parts of Canada and is typically found in swamp borders, wetlands, and near streams and ponds. The meaning of the specific epithet is obscure. It was said to be the common name applied to this plant in New England (but now no longer used). In classical Latin, it was the name used for an aromatic shrub. As this species is not aromatic, it is difficult to believe that New Englanders would have applied this name to the silky dogwood.

The silky dogwood prefers well-drained medium to wet acidic soils. It may be grown in full sun or partial shade, and it even tolerates close to full shade. The roots need to be kept cool and moist during the summer. It is recommended that 2 to 4 inches of mulch be added to protect the plant's roots. If the shrub branches touch the ground they may form roots at the nodes. 

This shrub is multi-stemmed, open and rounded and may grow 6 to 12 feet tall. The leaves and twigs have silky hairs. A distinctive feature of this shrub is the dark brown pith of 1- to 2-year-old stems and dark-reddish twigs. Clusters of creamy white flowers bloom in the spring followed by blue drupes that ripen late summer. The berry-like drupes appear in drooping clusters from August to September and attract many birds. Thickets may result if the growth of the shrub is not controlled. The shrub also may be propagated by seeds, cuttings, or layering.

This is a good shrub selection for moist to wet areas of the landscape. It is not overly ornamental and is somewhat wild and unkempt for placement in prominent areas. Consider the silky dogwood for moist woodlands, naturalized areas, or sites near streams/ponds. It is also effective for erosion control.

Quick ID Hints:

• open, rounded, medium-sized shrub
• silky hairs on the leaves and twigs
• creamy white clusters of flowers in the spring
• drupes ripen to dark blue in late summer
• dark-reddish purple twigs
• smooth gray bark
• dark brown pith in 1- to 2-year-old stems

Insects, Diseases, and Other Plant Problems: The silky dogwood has no serious insects or disease problems. It may be susceptible to scale. Borers and leaf miners are potential pests. Leaf spot, crown canker, blights, root rot, and powdery mildew may occur. Thickets may form if the shrub is not maintained.
