| Summary: | with small, alternate, oval leaves (22). The plant produces trailing stems or runners up to six feet long. The leaves, glossy-green in summer, turn dark red during the dormant season, which is approximately November through April. Short vertical branches two to eight inches tall, called uprights, grow from buds on the runners and produce both vegetative and fruit buds. Each fruit bud may contain as many as seven flowers. ● The cranberry root system is fine and fibrous (25). The roots absorb most of their nutrients through a symbiotic relationship with mycorrhizal fungi (14). In recent Massachusetts measurements, cranberry roots were found to penetrate soil to a depth of no greater than eight centimeters (3 inches) (17), although field observations have confirmed rooting depth of approximately five inches and lab studies have shown root growth to a depth of ten inches (Dr. Bruce Lampinen, personal communication, November 1999). ● After emerging from dormancy in May, the vines begin to develop new leaves followed by flowers. Flowering in Massachusetts typically begins mid-June and lasts from three to six weeks. Berries reach maturity approximately 80 days after full bloom and are harvested from early September through early November, depending on season and variety (25). The American Cranberry is native to North America and is found in natural bogs from Minnesota to Newfoundland |
