Bidens pilosa is a species of flowering plant in the aster family. It is native to the Americas but it is known widely as an introduced species of other regions, including Eurasia, Africa, Australia, and the Pacific Islands. It is a tall branched weed with thin yellow flowers that develop into a cluster of barbed seeds. Its many common names include black-jack, beggar-ticks, cobbler's pegs, and Spanish needle. The seeds are like short, stiff hairs. They get stuck in feathers, fur, or socks, etc. This bur is widespread throughout the warmer regions of the world. Its little black seeds hook onto clothes or horses and thereby the bur spreads itself around. It is susceptible to hand weeding if small enough, even then must be bagged, and thick mulches may prevent it from growing. Each seed has two to four barbed spines. A weed of gardens, woodlands, and waste areas, a person who brushes against it will end up covered in the burs and need to pick them off one by one. Although this plant is considered a weed in some parts of the world, in other parts it is a source of food or medicine. For example, it is reportedly widely eaten in Africa, and in Vietnam, during the Vietnam War soldiers adopted the herb as a vegetable, which lead to it being known as the "soldier vegetable".
