Viburnum lentago is a deciduous, upright, multi-stemmed shrub that can sucker and develop into a broad screening plant. It is a low-maintenance choice for gardeners who want a native shrub with a substantial presence rather than a compact container plant.

Where it grows best

Plant it in full sun or partial sun with moist to average, moderately drained or well-drained soil. It tolerates loam, clay, rich moist soil and average garden soil, with a soil pH from 5 to 7.5. It suits much of eastern and central Canada and is rated hardy from Canadian Zone 2 through Zone 7.

Garden and wildlife value

Nannyberry works well in wildlife gardens, naturalized plantings, hedgerows, windbreaks and screening. Its May flowers support pollinators, while the fruit feeds birds and mammals and the shrub provides wildlife cover. Ripe fruit is edible for humans, making it suitable for edible landscaping.

Everyday care

Water regularly during the first year after planting. Once established, water only during extended drought, because this shrub has limited drought tolerance. Its low maintenance needs make it useful where a large native planting can be allowed to develop with minimal routine attention.

What to do through the season

In spring, check that new plantings receive regular water as they establish. During summer drought, provide water when dry conditions are prolonged. Monitor shaded foliage during the growing season, especially where air movement and light are limited.

Problems and symptoms

Powdery mildew may affect foliage when the shrub receives too much shade. Road salt and deicing salts are another important risk, particularly beside treated roads, driveways and walkways. Wildlife browsing is generally expected to cause low damage.

Corrective and preventive care

Choose a site with adequate sun and avoid high-salt locations before planting. If foliage shows mildew symptoms, review whether the shrub is receiving too much shade. During extended drought, water established plants; do not rely on this shrub to tolerate prolonged dryness without help.

Before you plant

Allow room for a large shrub and possible suckering; it is not suited to small spaces or containers. Confirm that the site is not exposed to heavy deicing salt. Ripe fruit is edible for people, but the plant is mildly toxic to pets, so plan accordingly.
