“…Within the United Kingdom, the species has been dominant in several vegetation communities: the chickweed-Capsella and the chickweed-nettle (Urtica urens L.) communities, and in the plantain (Plantago major L.) and bindweed [Fallopia convolvulus (L.) Á. Löve]speedwell (Polygonum aviculare Poir.) subcommunities; and is a minor component of other communities of herbs including other crucifers such as field pennycress (Thlaspi arvense L.) and grasses, including meadow grass (Poa annua L.) and rye-grass (Lolium perenne L.) (Pigott et al 2000); while in other parts of Europe it is among plant communities dominated by members of the Chenopodioideae such as Amaranthus and Chenopodium spp., and among such communities in alpine pinespruce stands and in vineyards (Aksoy et al 1998;Konstantinovi ć and Blagojevi ć 2014). The species is ubiquitous in Germany, along with other species in the above-mentioned communities (Hanzlik and Gerowitt 2012).…”

Capsella bursa-pastoris (L.) Medik, shepherd’s purse, is a cosmopolitan summer or winter annual weed species distributed throughout temperate and subtropical regions of the world and is considered one of the most common plants on earth. It is an opportunistic annual that colonizes newly disturbed, open or dry environments and is ubiquitous in cultivated lands in Canada. In annual crops in western Canada, C. bursa-pastoris has been among the 20 most abundant weeds since the first weed surveys in 1970. It is most easily distinguished by its small white four-petalled flowers and its heart-shaped seed-pods, but exhibits considerable variation in leaf shape and flowering time. It has been used for food and medicine by numerous cultures. Its golden-brown seeds are produced in large numbers predominantly through self-pollination and can form a substantial seed bank, with reported values ranging to several hundred thousand seeds m-2. While seeds usually disperse near the mother plant, long-distance dispersal by attaching to vehicles, people and other vectors may be facilitated by its mucilaginous coat. Capsella bursa-pastoris does not produce fertile hybrids with other species of economic or ecological significance. It is generally well controlled by soil-applied and foliar (post-emergence) herbicides although its presence in agricultural fields may result in substantial yield loss, as documented in cole crops in North America and grain crops in Europe. The species can host a wide range of insect, nematode, fungal, viral, and bacterial pests that may damage crop species.
