Viburnum opulus var americanum (syn Viburnum trilobum) is a four-season beauty. It is a fantastic native shrub for a hedge or screen as it has a moderate growth habit of about 3 feet per year. The flowers last for about four weeks. Note: You need cross-pollination for the edible, bright red berries (3 or more is perfect). The fall color is a stunning bright red.

Maintenance: Viburnum Leaf Beetle may be a problem. Introduced from Europe and found initially on Viburnum opulus (European Cranberry Bush). The larvae and adults can defoliate a shrub. Severe damage usually does not kill the shrub, unless it happens yearly. For more information: http://idl.entomology.cornell.edu/wp-content/uploads/Viburnum-Leaf-Beetle.pdf. It will hybridize with Viburnum opulus var. opulus (European Cranberry Bush). This has created a loss of the native genotype. Be sure you are buying the correct plant by making sure the Latin name is clearly on the label. Many garden centers will sell you European Cranberry Bush. The berries on the European Cranberry Bush are not edible.


Benefits: Birds, small critters and people eat the berries (best picked after a good freeze), clay tolerant, nectar source, pollinators, host plant to the Spring Azure butterfly
