The black-eyed pea or black-eyed bean is a legume grown around the world for its medium-sized, edible bean. It is a subspecies of the cowpea, an Old World plant domesticated in Africa, and is sometimes simply called a cowpea.
The common commercial variety is called the California Blackeye; it is pale-colored with a prominent black spot. The American South has countless varieties, many of them heirloom, that vary in size from the small lady peas to very large ones. The color of the eye may be black, brown, red, pink, or green. All the peas are green when freshly shelled and brown or buff when dried. A popular variation of the black-eyed pea is the purple hull pea; it is usually green with a prominent purple or pink spot. The currently accepted botanical name for the black-eyed pea is Vigna unguiculata subsp. unguiculata, although previously it was classified in the genus Phaseolus. Vigna unguiculata subsp. dekindtiana is the wild relative and Vigna unguiculata subsp. sesquipedalis is the related asparagus bean. Other beans of somewhat similar appearance, such as the frijol ojo de cabra (goat’s-eye bean) of northern Mexico, are sometimes incorrectly called black-eyed peas, and vice versa.
History
Throughout the South, the black-eyed pea is still a widely used ingredient in soul food and cuisines of the Southern United States. The black eye pea is cultivated throughout the world. It originates from Africa and has been cultivated in China and India since prehistoric times. Cultivation also occurred in the Southern United States as early as the 17th century in Virginia as a result of enslaved persons growing and cultivating the seeds that they were able to transport with them while being abducted from their homelands. The crop would also eventually prove popular in Texas. The planting of crops of black-eyed peas was promoted by George Washington Carver because, as a legume, it adds nitrogen to the soil and has high nutritional value. Black-eyed peas contain calcium (41 mg), folate (356 μg), protein (13.22 g), fiber (11.1 g) and vitamin A (26 IU), among other nutrients, with less than 840 kilojoules (200 kilocalories) of food energy in a 171-gram (6 oz) serving.
Cultivation
This heat-loving crop should be sown after all danger of frost has passed and the soil is warm. Seeds sown too early will rot before germination. Black-eyed peas are extremely drought tolerant, so excessive watering should be avoided.
The crop is relatively free of pests and disease. Root-knot nematodes can be a problem, especially if crops are not rotated. As a nitrogen-fixing legume, fertilization can exclude nitrogen three weeks after germination.
The blossom produces nectar plentifully, and large areas can be a source of honey. Because the bloom attracts a variety of pollinators, care must be taken in the application of insecticides to avoid label violations.
After planting the pea, it should start to grow after 2–5 days.
Lucky New Year food
In the Southern United States, eating black-eyed peas or Hoppin’ John (a traditional soul food) on New Year’s Day is thought to bring prosperity in the new year. The peas are typically cooked with a pork product for flavoring (such as bacon, fatback, ham bones, or hog jowls) and diced onion, and served with a hot chili sauce or a pepper-flavored vinegar. The traditional meal also includes cabbage, collard, turnip, or mustard greens, and ham. The peas, since they swell when cooked, symbolize prosperity; the greens symbolize money; the pork, because pigs root forward when foraging, represents positive motion. Cornbread, which represents gold, also often accompanies this meal.
Several legends exist as to the origin of this custom. Two popular explanations for the South’s association with peas and good luck dates back to the American Civil War. The first is associated with General William T. Sherman‘s march of the Union Army to the sea, during which they pillaged the Confederates’ food supplies. Stories say peas and salted pork were said to have been left untouched, because of the belief that they were animal food unfit for human consumption. Southerners considered themselves lucky to be left with some supplies to help them survive the winter, and black-eyed peas evolved into a representation of good luck. One challenge to this legend is that General Sherman brought backup supplies with him including three days of animal feed and would have been unlikely to have left even animal feed untouched. In addition, the dates of the first average frost for Atlanta and Savannah, respectively, are November 13 and November 28. As Sherman’s march was from November 15 to December 21, 1864, it is improbable, although possible, that the Union Army would have come across standing fields of black-eyed peas as relayed in most versions of the legend. In another Southern tradition, black-eyed peas were a symbol of emancipation for African-Americans who had previously been enslaved, and who after the Civil War were officially freed on New Years Day.
Other Southern American traditions point to Jews of Ashkenazi and Sephardic ancestry in Southern cities and plantations eating the peas.
