Bunchberry Cornus canadensis
ABOUT
The plant commonly known as Bunchberry is a perennial which bears a distinct resemblance to the larger dogwood trees, even though it is low-growing. It features a whorl of six green leaves which grow outward in a star-like pattern from its central stem. During the flowering season, Bunchberry produces a set of small, clustered white flowers at the center of this whorl. Each flower cluster is actually a group of tiny, inconspicuous blooms surrounded by four large, petal-like bracts that can make the flowering head look like a single, large white bloom. After flowering, it produces clusters of bright red berries that are quite appealing to various forms of wildlife, as well as being a striking visual feature. The foliage can turn a beautiful reddish-purple color in the fall, adding to its seasonal interest.

- Water
Bunchberry, or Cornus canadensis, requires consistent moisture, so it should be watered deeply once a week with about one to two inches of water. During the growing season, especially if the weather is dry, check the soil moisture regularly and ensure that the soil does not dry out completely. It's best to water in the early mornings or evenings to reduce evaporation. During winter, reduce watering frequency as the plant's growth slows down and it requires less moisture. Use a watering can or a slow-drip system to avoid overwatering and to make sure the water penetrates deeply into the soil.
- Light
Bunchberry thrives best in dappled sunlight or partial shade. It should be planted in a spot that mimics its natural woodland habitat, where it can receive filtered light through taller trees or structures. It can tolerate some morning sun but should be shielded from the intense afternoon sun to prevent leaf scorch.
- Temperature
Bunchberry prefers cooler climates and does well in temperatures ranging from 60°F to 70°F. It can survive minimum temperatures down to about -40°F but will go dormant. Avoid exposing the Bunchberry to extreme heat, as temperatures consistently above 75°F may stress the plant and inhibit its growth.
- Pruning
Bunchberry generally does not require extensive pruning, but it can be beneficial to prune to remove any damaged or diseased stems to keep the plant healthy. Pruning should be done in early spring before the new growth starts. It's also a good idea to remove any old or spent flowers after they have finished blooming to encourage more blooms.
- Cleaning
As needed
- Soil
Bunchberry thrives in acidic soil with a pH of 4.5-6.0. A mix of peat moss, sand, and pine bark suits this plant well, mimicking its natural forest floor habitat.
- Repotting
Bunchberry does not typically require repotting as it is generally grown in the garden rather than in containers.
- Humidity & Misting
Bunchberry prefers moderate to high humidity levels, similar to those found in its native forest habitats.
- Suitable locations
Indoor
Ensure acidic soil, shade, and high humidity for Bunchberry indoors.
Outdoor
Plant Bunchberry in acidic soil with shade and moisture.

- Life cycle
Cornus canadensis, commonly known as Bunchberry, begins its life cycle as a seed which germinates in late spring or early summer. The seedling stage includes development of a rudimentary root system and a shoot with a whorl of leaves that photosynthesize to support further growth. As it matures, Bunchberry forms an underground rhizome, from which new shoots emerge annually; during this vegetative stage, the plant spreads laterally in ideal conditions. The reproductive stage follows, usually in late spring to early summer, when Bunchberry produces small, greenish-white flowers surrounded by four large, petal-like bracts that are often mistaken for the actual flowers. After pollination by insects, these flowers give way to a cluster of bright red berries, each containing seeds that disperse to continue the cycle primarily through animal endozoochory. In winter, Bunchberry becomes dormant, conserving energy until the return of favorable growing conditions.
- Propogation
Propogation time
Spring-Early Summer
The most popular method of propagation for Bunchberry (Cornus canadensis) is by seed. To propagate Bunchberry seeds, they should be sown fresh in the fall directly into a cold frame or outdoor seedbed. The seeds require a period of warm stratification followed by cold stratification to break dormancy, mimicking the natural seasonal changes. This can be done artificially by keeping the seeds at around 70°F (21°C) for 60-90 days, followed by 30°F to 40°F (-1°C to 4°C) for an additional 60-90 days. Once stratified, the seeds can then be sown in soil, ideally in a shaded area. Seedlings usually emerge in the spring and can be transplanted to their permanent location the following fall or the second spring after sowing.
