Cranberry plants grow in acidic bogs in cooler areas of the northern hemisphere. They are low creeping shrubs up to seven feet (3 m) long, from two to eight inches (5-20 cm) high. They have slender and wiry stems with small leaves which are evergreen with dark pink flowers. Cranberries are usually eaten during Thanksgiving in the United States. They are also eaten in Europe and some parts of South America.
