Wentworth Cranberrybush Viburnum

Wentworth American Cranberrybush Viburnum (Viburnum trilobum 'Wentworth')

Wentworth American Cranberrybush Viburnum is a tough, cold-hardy shrub that delivers privacy, seasonal color, and fruit that keeps the landscape looking alive into fall. It grows into a substantial, dense plant that works as a natural screen without feeling stiff or overmanaged. In late spring, white flower clusters brighten borders and bring pollinator activity into the garden. By late summer and fall, the plant loads up with glossy red fruit and often finishes with strong red to burgundy foliage.

Distinctive Features

This cultivar is selected for heavy fruiting, producing showy clusters of bright red, cranberry-like drupes that add color and can be used in preserves when fully ripe. Flat-topped white flower clusters appear in late spring, followed by fruit that often hangs on well into cool weather if birds do not claim it first. The leaves are three-lobed and maple-like, medium to deep green through summer, then turning red to burgundy tones in fall. The habit is upright to rounded and dense, making it a reliable backbone shrub for larger borders and screening.

Growing Conditions

• Sun: Full sun to part shade, with best flowering, fruiting, and fall color in full sun.
• Soil: Moist, well-drained soil is ideal, and it tolerates heavier soils when drainage is reasonable.
• Water: Medium moisture, watering regularly to establish and during extended dry periods.
• USDA Zones: Zones 3 to 7.
• Mature Size: About 8 to 12 feet tall and about 8 to 12 feet wide.
• Habit: Upright to rounded, multi-stemmed, and densely branched.
• Bloom Season: Late spring.
• Flower Color: White.
• Fruit: Bright red berry-like drupes ripening in late summer to fall.

Ideal Uses

• Focal Point: Use where the red fruit and fall color can create a bold seasonal highlight from key views.
• Screening: Plant in rows or staggered groups to build privacy with a full, natural look.
• Informal Hedges: Use as a tall hedge that looks finished without tight shearing.
• Back-of-Border Structure: Place behind perennials and smaller shrubs to add depth and a strong green backdrop.
• Wildlife Plantings: Include where fruit can support birds and add late-season garden activity.
• Native-Style Borders: Combine with other hardy shrubs and ornamental grasses for a layered, four-season planting.

Low Maintenance Care

• Pruning: Prune right after flowering if shaping is needed, since next season's blooms form on older wood.
• Watering: Water consistently the first growing season, then deep water during drought to support fruiting and reduce stress.
• Mulching: Mulch to conserve moisture and moderate soil temperature, keeping mulch pulled back from the stems.
• Feeding: Feed lightly in spring only if growth is weak, since average soils are usually sufficient.
• Pest Watch: Monitor for viburnum leaf beetle in areas where it is active and address early to protect foliage.
