Roughleaf Dogwood (Cornus drummondii) - How to Grow & Care Guide

Plant Snapshot

Common Name: Roughleaf Dogwood
Latin Name: Cornus drummondii
Hardiness Zones: USDA zones 4–8 (regional limits vary. Colder sites may have dieback, warmer sites may grow denser and spread more).
Typical Height: 6–20 ft (180–600 cm) tall at maturity.
Typical Spread: 6–16 ft (180–480 cm) spread. Can form dense colonies via suckers.
Bloom Period: Spring bloom, typically May–June in the Northern Hemisphere.
Soil Preferences: Adaptable from well drained to seasonally moist clay soils. Tolerates neutral to slightly alkaline pH. Poorly drained sites with prolonged standing water may cause decline.
Light Preferences: Full sun to part shade. More flowers and denser branching in sunnier sites, taller sparser growth in heavy shade.
Toxicity: Fruits are an important food for birds. ASPCA lists dogwoods as non toxic to cats and dogs. Human ingestion may cause mild stomach upset in some cases.
Propagation: Seed, root suckers, layering, and cuttings. Plants readily sucker to form colonies.

Key Facts

Forms multi stem clumps and suckering thickets.
Showy flat clusters of white flowers in spring.
Produces white to bluish white berries that feed birds.
Tolerates clay and seasonally moist soils.
Grows well in full sun to part shade.
Used in hedgerows and wildlife plantings.

Roughleaf Dogwood is a native multi stem shrub that produces flat clusters of white flowers in spring and white to bluish berries that feed birds. It makes a durable hedgerow or wildlife planting and will form suckering clumps that require management in small landscapes.

Identification

Multi stem shrub typically reaching 6 to 20 feet tall with a 6 to 16 foot spread as plants sucker and form colonies. Flowers appear in spring, typically May and June in much of its range, as flat clusters of white blooms followed by white to bluish white fruit that persist for birds to eat.

Where to grow and best uses

Native to the central United States, this dogwood performs well in hedgerows, wildlife buffers and naturalized edges. It tolerates full sun to part shade and adapts to clay and seasonally moist soils, making it a good choice for sites where heavier soils limit other shrubs.

Planting and spacing

Space plants at roughly their mature spread depending on use. For a formal hedge use spacing near 6 to 10 feet apart, and for natural screens allow 12 to 16 feet to let suckers form a colony. Set the root ball so the top sits level with the surrounding soil and firm soil around roots to remove air pockets.

Watering and soil

Tolerant of clay and seasonal moisture, this dogwood does not like prolonged standing water and will decline in poorly drained sites. Provide regular water while plants establish and then water only during extended dry spells. Poor drainage leads to root decline while drought shows as leaf wilting and sparse flowering.

After flowering care and pruning

Flowers finish in late spring and fruit follow. Remove dead or damaged stems and thin the oldest stems to encourage new growth and better flowering. Control suckering by removing unwanted shoots at the root or by cutting back stems to maintain shape and limit colony expansion.

Controlling spread and naturalizing

Plants spread by root suckers and can form dense thickets if left unmanaged. Contain spread by regular removal of suckers, installing root barriers where space is limited or by maintaining a clipped edge. In warmer areas expect more aggressive suckering and plan for ongoing maintenance.

Propagation

Propagate by seed, root suckers, layering or from cuttings. Seed germination often needs cold stratification while vegetative methods produce true to type material and speed establishment. Suckering provides an easy way to expand a planting but also requires attention when containment is desired.

Frequently asked questions

How fast does Roughleaf Dogwood grow?: Growth is moderate. Plants commonly reach several feet in a few years and can attain their 6 to 20 foot mature height over time depending on site quality and light.
Is Roughleaf Dogwood good for wildlife?: Yes. Flowers attract insects and the white to bluish berries are eaten by many bird species making it valuable in wildlife plantings.
Is it invasive?: It can naturalize by root suckers and form colonies. In small landscapes manage suckers to prevent unwanted spread.
What soil does it prefer?: Tolerant of clay and seasonally moist soils and adapts to neutral to slightly alkaline pH. Avoid sites with prolonged standing water.
Are the berries toxic to pets?: Cornus species are listed by the ASPCA as non toxic to dogs and cats but human ingestion may cause mild stomach upset. Check local poison resources for specific concerns.
