Capsella bursa-pastoris, known as shepherd's purse because of its triangular flat fruits, which are purse-like, is a small annual and ruderal flowering plant in the mustard family (Brassicaceae).^[2] It is native to eastern Europe and Asia minor,^[3] but is naturalized and considered a common weed in many parts of the world, especially in colder climates,^[4] including the British Isles,^[5] where it is regarded as an archaeophyte,^[6][7] North America^[8][9] and China,^[10] but also in the Mediterranean and North Africa.^[3] C. bursa-pastoris is the second-most prolific wild plant in the world,^[10] and is common on cultivated ground and waysides and meadows.^[11]

Scientists have referred to this species as a protocarnivore, since it has been found that its seeds attract and kill nematodes as a means to locally enrich the soil.^[12][13]
