Production statistics Production is limited to the northern US and Canada, where the bogs and plants exist naturally. About 1500 acres of cranberries are located near Vancouver, B.C., and 100 acres are harvested in the Maritime Provinces of southeast Canada. Ovary contains 4 locules and potentially 50 ovules, although few of these develop. Self-fruitful, no pollinizer. Insect or wind disturbance is necessary for pollen release.
Seedless fruit develops occasionally, but most fruit have some seeds.
Fruit bright red with waxy bloom at maturity, giving dark red to black appearance. Fruit mature in 60-120 days after fertilization, depending on cultivar and weather. Winter desiccation is more a threat than outright killing of tissues, and is the primary reason for winter flooding, although this also provides protection from low temperatures. The cuttings are either hand-placed or pushed into the sand by devices such as discs. Runners should cover the surface by the end of the season of planting, and uprights are formed the second year.
