Viburnum, a group of shrubs and small trees native chiefly to north temperate areas. There are 225 species, many of which are cultivated for their flowers and colorful autumn foliage. The flowers, commonly white or pink, are borne in broad clusters or in long spikes. The viburnum has small red or bluish-black fruits, similar to cranberries. The fruits tend to remain on the plant all winter.

Several species of viburnum are native to North America. The cranberry bush, found throughout the northern United States and much of Canada, is 8 to 12 feet (2.4 to 3.7 m) high. It bears white flowers and edible scarlet fruit. (The fruit used to make sauce, juice, and jelly is from a different, unrelated plant. The blackhaw, or stagbush, grows to 15 feet (4.6 m) high and bears bluish-black edible fruit. It is found from Connecticut to Florida and west to Texas.

The European cranberry bush, also called rose elder or whitten tree, is found in Europe, North Africa, and northern Asia. It has white flowers and scarlet fruit, and grows to 12 feet (3.7 m) high. A variety of this species called snowball, or guelder rose, is sterile.

The cranberry bush is Viburnum trilobum; blackhaw, V. prunifolium; Guelder-rose, V. opulus. Viburnums belong to the honeysuckle family, Caprifoliaceae.
