Introduction to Navy Beans

Navy beans, scientifically known as Phaseolus vulgaris, are small, white beans that belong to the legume family. They are a staple in many culinary traditions around the world, valued for their mild flavor, versatility, and nutritional benefits. Often referred to by other names like pea beans or haricot beans, navy beans have earned their moniker from their extensive use in the United States Navy since the mid-1800s, where they were a standard component of sailors' diets.

Origins and History

Navy beans have a rich history that dates back thousands of years. They are believed to have originated in the Americas, with evidence suggesting that indigenous peoples cultivated them long before European colonization. The beans were introduced to Europe and other parts of the world following the Columbian Exchange, where they quickly became a popular crop due to their adaptability and nutritional value.

Botanical Characteristics

Navy beans grow on bushy, non-climbing plants that reach about 12 to 24 inches in height. The beans themselves are small, oval-shaped, and smooth-textured. They develop in pods, each containing several beans. The plants thrive in well-drained soil with full sun exposure and require a growing period of approximately 85 to 100 days from planting to harvest.
