Gray Dogwood (Cornus racemosa): A Suckering Shrub for Slopes, Screens & Wildlife

Need to stabilize a steep slope or screen a property edge? Gray dogwood (Cornus racemosa) is a native workhorse. It suckers into dense thickets, tolerates dry shade, and feeds pollinators in spring, birds in fall/winter.

Key Trait: Clonal Spread

Gray dogwood spreads via suckers from the parent, forming genetically identical colonies. Upright, dense form. Not for small city lots (<¼ acre) — it needs room to colonize. Best in suburban/rural landscapes.

Design Uses

• Dense hedge/screen (tight spacing: 2.5–3')
• Massed on slopes for stabilization
• Woodland edge understory for screening
• Clustered nesting thicket for birds
• Not as a single specimen in a shrub border

Planting Notes

Cluster 3–5 plants, 4' apart. Large areas: fewer plants, wider spacing, let them fill in. Heads up: flowers have a musky odor some find unpleasant — site away from patios/decks.

Pollinator Value

Four-petaled creamy flowers produce pollen & nectar → native bees, beetles, occasional flies. Female mining bees (Andrena) and long-horned beetles are frequent visitors.
