Silky Dogwood (Cornus amomum) is a multi-stemmed shrub native to eastern North America, prized for its attractive white flowers and blue fruit.

Cornus amomum, commonly known as silky dogwood, is a deciduous shrub native to eastern North America, valued for its attractive foliage, seasonal blooms, and ornamental fruits. This species is a member of the Cornaceae family, a group of plants recognized for their distinctive flower and fruit structures. Silky dogwood plays a role in its native ecosystems, providing habitat and food for wildlife. This shrub typically grows to a height of 6 to 12 feet, often forming a dense, multi-stemmed thicket. Its growth habit is spreading, with arching branches that can give it a somewhat graceful appearance. The leaves are opposite, simple, and ovate to elliptical in shape, measuring about 2 to 5 inches long. They are typically dark green on the upper surface and paler, often with a silky pubescence, on the underside, which contributes to the common name. In autumn, the foliage often transforms into attractive shades of reddish-purple. The flowers of Cornus amomum are small and borne in flat-topped clusters, or cymes, typically appearing in late spring to early summer. Each individual flower is creamy white and has four petals. Following the bloom, the plant produces clusters of drupes, which are small, berry-like fruits. These fruits are initially greenish-white, maturing to a striking bluish-white or sometimes purplish-blue color by late summer or early autumn. The bark is generally dark brown to reddish-brown and can be smooth on younger stems, becoming more furrowed with age. Silky dogwood thrives in a variety of light conditions, from full sun to partial shade, and prefers moist, well-drained soils. It is adaptable to a range of soil types, including those that are somewhat wet, making it suitable for riparian areas and low-lying sites. Its native range extends across much of the eastern United States and southeastern Canada, where it is commonly found in woodlands, along stream banks, in swamps, and in moist thickets. The bluish fruits of Cornus amomum are an important food source for various bird species, including thrushes, waxwings, and woodpeckers, as well as small mammals. This ecological role makes it a valuable component of wildlife gardens and naturalized landscapes. While not typically cultivated for culinary purposes, its ornamental appeal lies in its layered branching, attractive summer flowers, and particularly its vibrant blue fruits that contrast beautifully with the autumn foliage. The plant's adaptability and resilience also contribute to its horticultural value, making it a reliable choice for naturalistic plantings and erosion control in moist areas.

Care guide for Silky Dogwood

Watering, pruning, propagation, and repotting details from plant data

Water

Silky Dogwood thrives in consistently moist soil. Water deeply and regularly, especially during dry spells and the first year after planting. Avoid waterlogged conditions, as this can lead to root rot.

Check soil moisture by inserting a finger a few inches down; water when the top layer feels dry.

Pruning

Prune Silky Dogwood in late winter or early spring before new growth begins. Remove dead, damaged, or crossing branches.

To maintain shape and encourage vigorous new growth for better flower and fruit display, consider thinning out older, less productive stems at the base. It responds well to rejuvenation pruning.

Propagation

Propagation is best achieved through softwood cuttings taken in late spring or early summer, or semi-hardwood cuttings in mid-summer. Root cuttings can also be taken in late winter.

Using rooting hormone can improve success rates. Seeds require a period of cold stratification before sowing to break dormancy.

Repotting

Repotting is rarely necessary for established landscape specimens as Silky Dogwood is a large shrub. If grown in a container, repot every 2-3 years in early spring before new growth emerges.

Use a well-draining potting mix and a slightly larger container to accommodate root growth.
