These plants belong to the [[genus|genera]] ''Brassica'' or ''Sinapis''. They have tiny [[seed]]s. These seeds can be used as a [[condiment]]. When they are first ground, and then mixed with [[water]], [[vinegar]] and other ingredients, a [[condiment]] called [[mustard]] can be made. The seeds can also be pressed, to give a kind of [[vegetable oil|oil]] called ''mustard oil''. Some kinds of mustard plants have edible leaves. These leaves are known as ''mustard greens''. Mild white mustard (''[[white mustard|Sinapis hirta]]'') grows wild in [[North Africa]], the [[Middle East]] and [[Mediterranean]] Europe and has spread farther by long cultivation; brown or Indian mustard (''[[Brassica juncea|B. juncea]]''), originally from the foothills of the [[Himalaya]], is grown commercially in the [[United Kingdom|UK]], [[Canada]] and the [[United States|US]]; black mustard (''[[Brassica nigra|B. nigra]]'') in [[Argentina]], [[Chile]], the [[United States|US]] and some European countries. In addition to the mustards, the genus ''Brassica'' also includes [[cabbage]]s, [[cauliflower]], [[rapeseed]] and turnips. There has been recent research into varieties of mustards that have a high oil content for use in the production of [[biodiesel]], a [[renewable energy|renewable]] liquid fuel similar to [[diesel]] fuel. The biodiesel made from mustard oil has good cold flow properties and cetane ratings. The leftover meal after pressing out the oil has also been found to be an effective [[pesticide]].<ref>[http://www.bioproducts-bioenergy.gov/pdf
