roughleaf dogwood

Scientific name: Cornus drummondii. Verified common names: roughleaf dogwood, rough‑leaved dogwood, Drummond’s dogwood. Family: Cornaceae. Genus: Cornus — a member of the dogwood group and taxonomically related to other Cornus species such as flowering dogwood and red-osier dogwood.

Form and size: A multi-stemmed shrub or occasionally a small tree, often forming dense clumps or thickets by root suckering. Plants typically reach shrub-size heights, frequently in the range of a few meters (several feet) but can vary with site conditions.

Flowers: Produces flat-topped clusters (cymes) of small, cream to white flowers. Individual flowers are inconspicuous, typically with 4 petal-like lobes, and appear in late spring to early summer.

Leaves: Leaves are opposite, simple, and elliptic to ovate in outline. Upper surfaces are noticeably rough or scabrous to the touch (hence the common name); margins are generally entire. Venation is pinnate and visible.

Fruits and bark: Fruits are clustered drupes that ripen to whitish or pale shades and persist into fall and winter. Stems may become furrowed or blocky with age; the species is not known for the showy exfoliating bark of some other dogwoods.

Seasonal variation: Flowering occurs in spring/early summer, followed by fruiting in late summer to fall. Leaves turn color and fruits persist into colder months, offering winter interest and wildlife food.

Grows commonly in open woods, woodland edges, savannas, prairies, rocky glades, fence rows and disturbed sites. Typically tolerates a range of soil types including clay and calcareous soils and is often found on dry to mesic sites. Light preferences range from full sun to partial shade; plants commonly establish in sunny openings and along edges. Geographic distribution includes many central and eastern U.S. states (examples: AL, AR, GA, IA, IL and others), where it is commonly encountered in suitable habitats.

Flowers attract a variety of insect pollinators, including bees and other small insects. Fruit is an important late‑season food source for birds and small mammals; seeds are dispersed largely by frugivorous birds. Dense thickets provide shelter and nesting cover for wildlife.

Used in native‑plant and wildlife landscaping for hedgerows, erosion control and wildlife habitat due to its thicket-forming habit and reliable fruit production. Fruits are primarily valued for wildlife rather than for human consumption. No widespread, well-documented traditional medicinal uses are presented here.

Cornus drummondii is generally not considered at risk across its range and is often a resilient, colonizing species. Notable adaptations include tolerance of a range of soils and the ability to resprout and form dense thickets after disturbance, making it important for early successional and edge communities. The rough, scabrous leaf surface is a distinctive field character useful for identification.
