Viburnum trilobum é una specie originaria del Nordamerica settentrionale. Assume le dimensioni di un grande cespuglio e assomiglia notevolmente al nostro Viburnum opulus. Produce un’abbondante quantità di frutti che assumono la caratteristica colorazione rossa sin dalla fine del mese di luglio e rimangono sulla pianta fino all’inizio della primavera, allorché vengono finalmente apprezzati anche dagli uccelli selvatici. Il fogliame assume una vistosa colorazione autunnale.

The American Highbush Cranberry is native to swampy woods, bogs, lake margins, pastures, thickets, slopes and moist low places from New Brunswick to British Columbia south to New York, the Great Lakes, South Dakota and Oregon. It is a deciduous shrub with a rounded, upright spreading and sometimes arching habit. It typically grows to 10 to 15 feet tall. The leaves are three lobed, maple-like, shiny dark green turning an attractive yellow red or reddish purple in the fall. In spring it features an outer ring of 3/4 inch white sterile flowers surrounding the fertile but inconspicuous inner flowers, in a 3 inch flat-topped cluster. The flowers are followed by drooping clusters of cranberry like bright red 1/4 inch edible berries (drupes) in the fall.The berries are edible fresh off the shrub and are much less bitter than those berries found on Viburnum opulus. The berries are sometimes used to make jams and jellies.
American Highbush Cranberry is not related to true cranberries; the name comes from its tart, edible red fruits.
