Cornus canadensis is a low growing mat forming groundcover native to northern forests and alpine woodlands. Known as bunchberry, it produces small dogwood shaped white bracts in spring followed by bright red berries in late summer that attract birds and small mammals. Its spreading rhizomes and whorled foliage create a lush woodland carpet ideal for moist shaded environments.
Height & Spread: 4 - 8 in x 12 - 24 in
Bloom Time: Late spring to early summer
Light Requirements: Part shade to full shade
Soil Preference: Moist, acidic, well drained soil rich in organic matter
Watering Needs: Consistent moisture; avoid drying out
Deer Resistance: Generally deer resistant but young shoots may be browsed
Native Status
Cornus canadensis is native to northern North America, thriving in boreal woodlands and mountainous regions. It plays a key role in native woodland ecosystems and is an important food and cover source for wildlife.
WILDLIFE & INSECTS
Birds
- Bright red summer berries are consumed by thrushes, warblers, and grouse.
Butterflies
- Visited by Spring Azure butterflies for nectar and cover in early woodland growth.
Small Mammals
- Provides edible berries and protective ground cover for chipmunks and squirrels.
Spacing & Landscape Use
Spacing Recommendations:
- Space 12 - 18 in apart for fast spreading groundcover effect.
Landscape Placement:
- Ideal in woodland gardens, shaded pathways, or underplantings for native trees where cool moist soil is present.
Companion Plants
- Maianthemum racemosum (False Solomons Seal) - Arching stems and plumes of white flowers add height behind spreading Cornus canadensis.
- Polystichum acrostichoides (Christmas Fern) - Offers evergreen fronds and a lush texture contrast to bunchberry’s low mat.
- Mitchella repens (Partridgeberry) - A complementary groundcover that also produces red berries and thrives in acidic soils.
- Aruncus dioicus (Goat’s Beard) - Tall feathery blooms add vertical interest and create a layered woodland habitat.
- Trillium grandiflorum - Native spring bloomer with showy white flowers that pairs well in moist shade settings.
