The peanut is a plant of the legume, or pea, family, and its seeds form in pods. Peanut plants grow to just over one foot in height and spread about three feet. Peanut plants are self-pollinating, meaning that both male and female flowers appear on the same plant. Once the flowers wilt, the flower stalk grows down into the ground about an inch deep, where its ovary develops into pods containing the nuts, or seeds. Once the seeds mature, they can be harvested. Harvesting is a two-part process. First, a digger with a four-to-six inch horizontal blade is driven down the rows. This loosens the plants from the root while a shaker lifts and inverts it, exposing the pods to sunlight. Once the pods dry out for a few days, a combine or thresher cuts the pods from the vines, places the pods in a hopper on top of the machine, and replaces the vines and stems on the ground, where they serve as moisture-retaining mulch. The harvested pods are then placed in drying containers to cure, reducing their moisture content to around 10 percent.
Peanuts thrive in warm, subtropical climates and in sandy, well-drained chalky soils, both attributes of southern Alabama. Shelled raw peanut, which are the plant's seeds, are planted after the last spring frost when the soil temperature reaches around 65°F, usually in March or April. Harvesting takes place in September or October, anywhere from 120-160 days after planting. Peanuts are a dual crop, grown for both the nut itself and for peanut hay.

Peanuts originated in South America, and African slaves first brought them to the English colonies in the eighteenth century. Until the U.S. Civil War, members of the upper classes shunned the legume, considering it food fit only for slaves and the poor. Peanut consumption was largely relegated to people of the lower classes, who bought them from vendors and consumed them at fairs and circuses and on urban street corners. The entire practice of cracking open the pods, chewing the nuts, and tossing the empty shells on the ground gave the peanut an unrefined air. However, peanut consumption continued to spread, and farmers around the country began to experiment with growing the crop. Peanuts became more widely consumed during the Civil War, when both Union and Confederate soldiers valued them for their nourishing qualities. In addition to raw, roasted, and boiled, they enjoyed the peanut in various other forms including pies or peanut coffee.

Concurrently, cotton farmers faced several problems that made peanuts attractive as an alternative crop. Cotton had dominated antebellum agriculture in Alabama and the rest of the South. Alabamians also grew corn, but sparingly. The crop lien system, under which creditors provided loans only under the condition that farmers grow cotton, made the production of other crops financially impractical. After the Civil War and Reconstruction, farmers reaped diminishing returns from cotton because it depleted nutrients in the soil and was plagued by the ravaging effects of the boll weevil. Seeking an alternative, many farmers turned to the peanut. The rise in the peanut's popularity was timely. Bolstered by new agricultural crop diversification strategies, the invention of labor-saving equipment that made planting, cultivating, harvesting, shelling, and cleaning peanuts easier and more efficient, and the discovery of its many uses, the peanut became a viable cash crop for southern farmers, who began growing peanuts on a significant scale.
George Washington Carver, of Alabama's Tuskegee Institute (now Tuskegee University) played a significant role in the popularization of the peanut, although there are some questions about the legitimacy of Carver's many purported innovations in the cultivation, harvesting, and uses of the peanut. Contrary to popular belief, Carver did not invent peanut butter, and there is some debate over who did. John Harvey Kellogg received the first U.S. patent for a "Process of Preparing Nut Meal" in 1895, followed by Ambrose Straub's patent for a "Peanut Butter Making Machine" in 1903. Many scholars now believe that Carver's contribution was more as a promoter than an innovator. He encouraged black farmers to begin growing peanuts for their soil enrichment qualities and as part of a system of crop diversification. Carver also spoke before the U.S. Congress about how the peanut could benefit the American economy. The Ways and Means Committee of the House of Representatives was at the time considering placing a tariff on peanut imports that would aid peanut growers in the United States, and Carver's presentation persuaded Congress to pass the bill.
