'''''Fallopia convolvulus''''', the '''black-bindweed''' or '''wild buckwheat''', is a fast-growing [[annual plant|annual]] [[flowering plant]] in the family [[Polygonaceae]] native throughout [[Europe]], [[Asia]] and northern [[Africa]].<ref name=europe>Flora of NW Europe: [http://ip30.eti.uva.nl/BIS/flora.php?selected=beschrijving&menuentry=soorten&id=2028 ''Fallopia convolvulus'']{{Dead link|date=August 2019 |bot=InternetArchiveBot |fix-attempted=yes }}</ref><ref name=china>Flora of China: [http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=242100055 ''Fallopia convolvulus'']</ref><ref name=pakistan>Flora of Pakistan: [http://www.efloras.org/florataxon.aspx?flora_id=5&taxon_id=242100055 ''Fallopia convolvulus'']</ref><ref name=Blamey>Blamey, M. & Grey-Wilson, C., 1989.

==Description==
Black-bindweed is a [[herbaceous]] [[vine]] growing to {{convert|1|–|1.5|m|in|abbr=on}} long, with stems that twine [[clockwise]] round other plant stems. The alternate triangular [[leaf|leaves]] are 1.5–6 cm long and 0.7–3 cm broad with a 6–15 (–50) mm petiole; the basal lobes of the leaves are pointed at the petiole. The [[flower]]s are small, and greenish-pink to greenish white, clustered on short [[raceme]]s. These clusters give way to small triangular [[achene]]s, with one [[seed]] in each achene.<ref name=europe/><ref name=china/><ref name=pakistan/><ref name=arable>Phil Wilson & Miles King, ''Arable Plants – a field guide'': [http://www.fieldguide.co.uk/?PP=species_account&SPID=3&SHC=4&PSD=2 Black-bindweed]</ref> The flowers have 5 [[sepals]], the 3 outer ones are larger and show a keel. It has 5 stamens and the fruit grows to 4 mm long.<ref>Parnell, J. and Curtis, T. 2012. ''Webb's An Irish Flora.'' Cork University Press. {{ISBN|978-185918-4783}}</ref>

While it superficially resemble bindweeds in the genus ''[[Convolvulus]]'' there are many notable differences; it has ocrea (stipule-sheath at nodes), which ''Convolvulus'' does not; and ''Convolvulus'' has conspicuous trumpet-shaped flowers while Black-bindweed has flowers that are unobtrusive and only about 4 mm long.<ref name=Blamey/>

==Distribution and habitat==
''Fallopia convolvulus'' grows most commonly on disturbed or cultivated land, in northern Europe typically on warm, sunny, well-drained sandy or [[limestone]] soil types,<ref name=Blamey/><ref name=arable/> but in hotter, drier areas like Pakistan, on moist shady sites.<ref name=pakistan/> It ranges from sea level in the north of its range, up to 3600 m altitude in the south in the [[Himalaya]].<ref name=china/><ref name=pakistan/><ref name=Blamey/>

==Cultivation and uses==
The seeds are edible, and were used in the past as a food crop, with remains found in [[Bronze Age]] middens.<ref name=Blamey/> The seeds are too small and low-yielding to make a commercial crop, and it is now more widely considered a [[weed]], occurring in [[agriculture|crops]], waste areas and roadsides. It can be a damaging weed when it is growing in a [[garden]] or crop, as it can not only damage the plants around which it twines, but also clog the machinery used to harvest a given crop. It is also an [[invasive species]] in [[North America]].<ref name="ars-grin.gov"/>
