Beans are one of the longest-cultivated plants. The common bean has been grown for about six thousand years in the Americas.
There are many websites that can help you with bean history. These two sites, in particular, provide useful information:
Beans are planted in May and take about 12-14 weeks to grow to full height. Once the plant has matured, it begins to develop small flowers that vary in color depending on the bean variety. The flowers give way to pods, within which the small beans begin to form. The warm summer days ripen the beans inside the pods. One or two weeks before harvest, the plants change color from green to golden yellow, signaling they are ready for harvest. The American bean harvest begins in August and continues in various parts of the country until late October.
World War II increased the demand for beans, as they became a staple in the C-rations used by US servicemen around the world. After the war, as the USs food relief efforts around the world intensified, so did dry bean production.
