American Highbush Cranberry, Viburnum trilobum, Shrub Seeds
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.
