Snowberry (Symphoricarpos × chenaultii)
Symphoricarpos × chenaultii (Snowberry) is a low-maintenance, suckering shrub noted for its showy pink-flushed white berries persisting into winter.
Complete Plant Information
Overview
The Snowberry, scientifically known as Symphoricarpos × chenaultii, offers exceptional late-season interest in the landscape, largely due to its persistent, showy fruit display. This deciduous shrub, a garden hybrid, matures into a dense, multi-stemmed specimen ideal for informal hedging or screening purposes. Its adaptability makes it a popular, low-effort choice for diverse garden settings throughout its hardiness range.
Symphoricarpos × chenaultii is valued for its resilience and tolerance of less-than-perfect conditions once established. It develops dark green foliage that sets off the unique berries, which often emerge white but are interestingly flushed with pink where exposed to direct sunlight. The shrub’s somewhat procumbent, arching growth habit gives it structure even during winter months.
Gardeners appreciate the low maintenance associated with this plant, as it requires minimal intervention beyond occasional pruning. Its ability to handle varying soil conditions and tolerate deer browsing further increases its practical value. Incorporating Symphoricarpos × chenaultii ensures long-lasting visual appeal well into the colder seasons.

How to Grow
The Symphoricarpos × chenaultii adapts well to average, medium moisture, well-drained soils. Plant during the dormant season (late winter or early spring) to allow roots to establish before summer heat. While it prefers full sun to partial shade for best flowering and fruiting, it tolerates a wide range of soil compositions, making site selection relatively flexible.
Watering requirements are medium; ensure consistent moisture, especially during the first year after planting. Fertilizing is rarely necessary if grown in adequate garden soil. Due to its tendency to sucker—producing new shoots from the base or roots—pruning is recommended to control shape and size.
Perform pruning as needed in late winter or early spring before new growth begins. Removing older, less productive wood encourages fresh, vigorous stems that will produce berries later in the season. Be prepared for the shrub to spread via suckering, which can be beneficial on slopes but requires containment in formal beds.
Landscape Uses
The suckering nature of Snowberry makes it an exceptional candidate for stabilizing slopes or banks where other ornamental shrubs might struggle to hold soil. It functions effectively as a casual shrub border or can be planted closely together to form a natural, informal screen or low hedge. Its hardiness and relatively fast growth rate contribute to quick coverage.
For foundational plantings, use Symphoricarpos × chenaultii where a less formal structure is desired, as its arching stems provide movement. Its tolerance for deer browsing means it remains intact where other desirable plants are frequently nibbled. For large properties, naturalize this Coralberry in open woodland areas where it can spread comfortably without needing rigorous boundary control.

Fruit Qualities
- Showy
Noteworthy Characteristics
Symphoricarpos × chenaultii, commonly known as chenault coralberry, typically matures to 3-6’ tall. It is a suckering shrub with arching stems and a procumbent growth habit, derived from parents S. Microphyllus and S. Orbiculatus. Elliptic to broad-ovate dark green leaves have downy undersides, followed by bell-shaped pink or white flowers that are often ornamentally insignificant but yield showy white berries flushed pink in the sun. These berries mature in early fall and typically persist into late fall or winter, providing excellent visual interest after the leaves drop.

- Deer
- Erosion
Potential Problems
Symphoricarpos × chenaultii is generally celebrated for having no serious insect or disease problems under most conditions. However, gardeners should remain vigilant for sporadic issues such as powdery mildew, which can manifest in humid or shaded conditions. Scale insects may occasionally infest woody stems, and aphids are sometimes observed, particularly on tender new growth. Good air circulation, achieved through proper spacing and timely pruning, helps mitigate fungal issues like anthracnose and mildew.
Frequently Asked Questions

Symphoricarpos × chenaultii is hardy and thrives in USDA Zones 4 through 7.
How large does Snowberry grow?
This shrub typically reaches a height between 3 and 6 feet, with a comparable spread of 3 to 6 feet at maturity.
When does Snowberry bloom?
The blooming period for this Coralberry is generally from June into July, producing small, often inconspicuous pink flowers.
What sun exposure does Symphoricarpos × chenaultii need?
It performs best when situated in areas receiving full sun to partial shade.
Conclusion
The Symphoricarpos × chenaultii, or Snowberry, earns its place in the garden through reliable, low-maintenance performance and striking winter berry clusters. Its tolerance for erosion and grazing animals makes it functionally superior for challenging sites where other shrubs fail. Before planting, confirm your location falls within USDA Zones 4-7 and prepare for its natural spreading habit by giving it adequate space or planning yearly pruning.
Companion Planting
Selecting companions that thrive in similar moisture and light conditions will enhance the overall health of your planting scheme involving Snowberry. Consider pairing Symphoricarpos × chenaultii with later-blooming perennials that can fill the space once the shrub’s summer flowers fade, providing continuous textural contrast. Native grasses or groundcovers that benefit from medium moisture and tolerate part-shade conditions work well underneath the canopy of this shrub.
Seasonal Care Calendar
Spring is the optimal time for maintenance; prune the Snowberry moderately in late winter or early spring to shape the shrub and remove any winter-damaged wood. As temperatures rise in late spring, monitor closely for early signs of aphids settling on new growth, treating promptly with horticultural soap if necessary. During the summer, maintaining medium soil moisture is key during dry spells, though established plants are quite resilient. Focus shifts to observing the developing fruit in fall, while late-season pruning should be avoided to preserve the attractive winter display.
