Cornus canadensis L.
Bunchberry dogwood, Canadian bunchberry
Cornaceae (Dogwood Family)
Synonym(s): Chamaepericlymenum canadense, Cornella canadensis, Cornus canadensis var. dutillyi
USDA Symbol: coca13
The slender 3-6 in. stalks of this perennial, woodland ground cover are topped by a whorl of oval, pointed leaves above which rises a white to greenish, dogwood blossom. Erect stems grow in extensive low patches, with 1 whorl of leaves at top and, just above, a cluster of tiny greenish flowers surrounded by 4 ovate white or pinkish bracts. The flower cluster resembles a single large flower held on a short stalk above leaves. A cluster of bright red berries follows. The leaves, which are dark-green and shiny in summer, become wine-red in fall. It spreads by underground stems.
Among the smallest of a genus of mostly shrubs and trees, Bunchberry makes an excellent ground cover in the moist woodland garden and is equally attractive in flower or fruit. Its natural range extends from Greenland across northern North America to northeast Asia. In the continental US, it is limited mostly to mountainous regions. This showy wildflower and Northern Dwarf Cornel (C. suecica) of the northern forests are the only herbs in the dogwood group, the other members being trees or shrubs. C. suecica ranges across northern Eurasia and much of northern North America, as far south as the St. Lawrence River and as far east as Nova Scotia. It has small purple flowers surrounded by 4 bracts.
The genus cornus is Latin for a horn.
