W.T.Aiton }} Lepidium campestre, the field pepperwort[1] or field pepperweed, is usually a biennial with some form of annual plant in the Brassicaceae or mustard family, native to Europe, but commonly found in North America as an invasive weed. The most notable characteristic of field pepperweed is the raceme of flowers which forks off of the stem. These racemes are made up of first small white flowers and later green, flat and oval seedpods each about 6 mm long and 4 mm wide.[2] Each seedpod contains two brown, 2.5 mm long seeds. The stem of field pepperweed comes out of a basal rosette of toothed leaves. The stem is covered in leaves, which are sessile, alternate and arrow-shaped.[2] The entire plant is generally between 20 and 60 cm tall and covered in small hairs.[2] Cultivation and usesField pepperweed grows in disturbed land, crops, and waste places.[2] It can tolerate most soils. The plant is edible. The young leaves can be eaten as greens, added raw to salads or boiled for ten minutes.[3] The young fruits and seeds can be used as a spice, with a taste between black pepper and mustard. The leaves contain protein, vitamin A and vitamin C.[3] The seed has the capacity to produce oil, and field pepperweed can be domesticated in the future as oil crop species.[4] References1. ^{{cite web|title=BSBI List 2007 |publisher=Botanical Society of Britain and Ireland |url=http://www.bsbi.org.uk/BSBIList2007.xls |format=xls |accessdate=2014-10-17 |deadurl=yes |archiveurl=https://www.webcitation.org/6VqJ46atN?url=http://www.bsbi.org.uk/BSBIList2007.xls |archivedate=2015-01-25 |df= }} 2. ^1 2 3 Richard H.
