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]
