Black Mustard (Brassica nigra) is a variety of Mustard Greens with black Mustard Seeds. Black Mustard is grown in Argentina, Chile, the US and some European countries.


Black Mustard Greens are available all year long.


Mustard Greens have some frost tolerance but grow best in temperate regions. Mustard seeds generally take three to ten days to germinate if placed under the proper conditions, which include a cold atmosphere and relatively moist soil. Brown Mustard Seeds and Black Mustard Seeds have higher yields than White Mustard Seeds. With enough time, mature Mustard plants grow into shrubs.

India, Nepal, China, Japan are among the leading producers of Mustard Greens, the U.S. grows a significant quantity of Mustard Greens as well. Major producers of mustard seeds include Canada, Hungary, Great Britain, India, Pakistan and the United States.
