cranberry tree (also called high-bush cranberry), Viburnum opulus var americanum (previously V. trilobum), a shrub or small tree of Canada and the northern states of the USA, which bears berries similar in appearance and quality to the cranberry, but with large stones inside (and belonging to a different family). A few cultivars have been developed. In Europe, V. opulus has been cultivated in some places.
The berries of the American cranberry tree produce an excellent jelly, and can be used for most purposes in the same way as cranberries proper. They have the same tart but pleasant flavour.
