Black Peanut! These yellow flowers pollinate themselves (!!!), drop their petals, and a budding ovary (called a peg) forms and enlarges and grows down and away from the plant to penetrate the soil. The peanut embryo is in the tip of the peg (see the peg on my finger). It will grow the peanut underground. (Thanks National Peanut Board for some of this language). This plant is growing at Pentridge Children's Garden in West Philly, and it's parents were grown last year in my seed keeping bed at Bartram's Garden in Southwest Philly, and before that by William Woys Weaver at Roughwood Seed Collection in Devon, PA, who was given seed by Harvey Yow in Seagrove, NC. Peanuts were introduced to North America by Africans beginning in the 1700s. Before that, they had been brought from South America to Spain and then Asia and Africa during the slave trade. West Africans had domesticated the Bambara Groundnuts, which grow its pods on pegs underground as well, and so the peanut was an easy to adopt crop. An Angolan word "mpinda" was transformed by the Gullah people of South Carolina to "pindar" to describe Bambara Groundnuts, and then Peanuts as well. I have some South Carolinian friends who still use the word "pindar" for peanut. Also, as many of us know, Dr. George Washington Carver, a Black scientist, inventor, educator, etc. did a lot of research, innovation, and farmer education with Black and White poor farmers across the South as a way to make profits and feed families after King Cotton. Peanuts are likely from the valleys of Paraguay originally. Thanks humans near and far, past and present, for tending to and shaping this beautiful, nourishing, and impressive food plant.
