Cranberry plants grow as small, trailing evergreen shrubs.
Their flowers range from pink to purple and bloom from May to August, depending on the type. The berries are harvested in the fall. Cranberries and their juice have been used for treating and preventing urinary tract infections. Cranberry juice has a promising use as a urinary deodorant. The bad odor of fermenting urine from people who have lost bladder control is a common problem in hospitals and long-term care facilities.
