Cornus drummondii C.A.Mey. — Midwestern roughleaf dogwood

Introduction

Midwestern roughleaf dogwood is a coarse-leaved shrub or small tree of central North America, common along woodland margins, ravines, stream corridors, and disturbed edges. The rough foliage and usually white mature fruits distinguish it from the southeastern eastern roughleaf dogwood, C. asperifolia, whose fruits are typically blue or bluish (Deasy et al. 2026). It belongs to Subgenus Thelycrania.

Historical treatments often reduced this plant to C. asperifolia var. drummondii, but that combination is based on the same type as C. drummondii. Tree TSAR follows current species-level recognition. The priceae names also fall within this species rather than representing an accepted infraspecific lineage.

Horticultural and Agricultural Uses

Cornus drummondii is valued more for function than refinement. Its dense growth, tolerance of exposed sites, and ability to colonize stream margins make it useful in windbreaks, slope stabilization, shelterbelts, and wildlife plantings. In rich alluvial soils it can become much larger than the modest shrub often seen in gardens (Deasy et al. 2026).

The species spreads vegetatively and can form thickets, a feature that is useful in erosion control but should be anticipated in smaller landscapes. Cultivars or selected forms exist, but they are secondary to the species’ ecological and engineering value.

Conservation Concerns

Kew reports Cornus drummondii as Least Concern, and it remains broadly distributed across central North America. It can be locally abundant and is not presently a species of high global extinction concern (Royal Botanic Gardens, Kew 2026).

Its vigorous clonal growth can, however, become a management issue where fire suppression allows woody thickets to expand into prairie or open floodplain systems. Conservation management is therefore context-dependent: the same native species can be desirable in riparian restoration yet require control where maintaining open prairie structure is the objective.
