Lepidium virginicum
''Lepidium virginicum'', also known as least pepperwort, Virginia pepperweed or peppergrass, is an annual or biennial plant in the Brassicaceae or mustard family. It is native to much of North America, including most of the United States and Mexico and southern regions of Canada, as well as most of Central America. It can be found elsewhere as an introduced species.
==Description==
As with ''Lepidium campestre'', Virginia pepperweed's most identifiable characteristic is its raceme, which comes from the plant's highly branched stem.〔Richard H. Uva, Joseph C. Neal and Joseph M. Ditomaso, ''Weeds of The Northeast'', (Ithaca, NY: Cornell University Press, 1997), Pp. 178-179.〕 The racemes give Virginia pepperweed the appearance of a bottlebrush.〔 On the racemes are first small white flowers, and later greenish fruits. The entire plant is generally between 10 and 50 centimeters tall.
The leaves on the stems of Virginia pepperweed are sessile, linear to lanceolate and get larger as they approach the base.〔 Note that all parts of the plant have a peppery taste.
