Cranberries are tart, red, evergreen berries native to North America, growing on low vines in bogs, known for rich antioxidants like proanthocyanidins (PACs) that help prevent bacteria from sticking to cells, often used in juices, sauces, and supplements, especially for urinary tract health, with cultivation primarily in the U.S. and Canada. 

What They Are:

• Plant: A low-growing, woody, evergreen shrub in the heather family (Vaccinium genus), related to blueberries and lingonberries.
• Habitat: Grown commercially in flooded bogs, requiring acidic soil.
• Botanical Name: Vaccinium macrocarpon (American Cranberry). 

Key Characteristics:

• Flavor: Tart and tangy.
• Color: Ranges from pink to deep red; some varieties are white.
• Nutrition: Rich in Vitamin C, fiber, and powerful antioxidants (polyphenols, anthocyanins, PACs). 

Uses & Benefits:

• Urinary Tract Health: PACs help prevent bacteria (like E. coli) from adhering to urinary tract walls, reducing recurrent UTIs.
• Culinary: Juices, sauces (like Thanksgiving sauce), dried snacks, baked goods.
• Historical: Used by Native Americans for food, medicine, and dye. 

Interesting Facts:

• Name Origin: Settlers called them "crane-berries" as the blossoms looked like cranes' heads.
• Harvest: Usually harvested in fall (Sept-Oct) by flooding bogs (wet harvest) or combing vines (dry harvest).
• Major Producers: The U.S. (especially Wisconsin & Massachusetts) and Canada are leading producers.
