American Cranberrybush Benefits Birds and Other Garden Wildlife

Collector: L. Linnaeus Locale: Virginia occ. Date: 20 OCT 2025 Catalog: HV-5299

If you're putting together a bird garden, rain garden, or woodland edge, American cranberrybush (Viburnum opulusvar.americanum) deserves a spot on your list. This northern native shrub gives you showy spring flowers, nice-looking foliage through the season, and vivid red fall fruit. The flowers feed pollinators, and it's even a larval host plant for moths and butterflies — so it's really pulling its weight for wildlife.

American cranberrybush fruit ripens in the fall, while its leaves take on yellow to reddish tones. The fruit will shrivel and darken after frost and consistent cold weather. It is very attractive to b

Common name: American cranberrybush, highbush cranberry

Botanical name: Viburnum opulusvar.americanum; syn. Viburnum trilobum

Origin: You'll find it in woods, thickets, and along riverbanks across roughly the northern half of the US and throughout Canada.

Flowers/fruits: In mid-spring, you get these round, flat-topped white flower heads about three inches across, made up of a mix of tiny fertile florets in the center and showier sterile florets around the edges. Then come clusters of oval-shaped fruits that ripen to a deep red in fall — they're edible and birds absolutely love them.

The flowers of American cranberrybush are of the lacecap type, with a central cluster of small, fertile florets and an outer ring of larger sterile florets. While many viburnums need to be planted in

Foliage: The leaves are rounded with toothed edges and three distinct lobes — they really do look like maple leaves. They're a nice medium green through the growing season, then shift to yellowish or purplish red in the fall.

Size and habit: This is a deciduous shrub that reaches 8 to 12 feet tall and wide at maturity, with a rounded shape formed by dense upright to arching stems.

Growing American cranberrybush

Exposure: Full sun to part shade

How to grow it: American cranberrybush is super easy to grow — just plant it in full sun or part shade in average, well-drained soil. It likes regular moisture but can handle brief periods of flooding, too. An annual topdressing of compost or leaf mould will really help with flowering and fruiting. Here's a bonus: unlike a lot of garden viburnums, this one doesn't need a partner plant to set fruit — its flowers are self-fertile! USDA Zones 2–7.
