General Information
Mustard greens have broad, wavy frilled leaves with longitudinal veins and a deep green color. The upright leaves are supported by coarse stems that can be quite fibrous when fully mature. Smaller leaves are considerably tenderer, while larger Mustard greens require cooking. They have a succulent yet crunchy texture and a robust flavor reminiscent of pepper and horseradish.
History
Mustard greens are native to India. The first varietal differentiation of mustard greens was cultivated in China near Sichuan. Mustard greens have been naturalized throughout the northern hemisphere from Japan to Europe to South and North America. Though very tolerable of a variety of climate and soil conditions, Mustard greens prefer rich organic nutrient-dense soils, full sun and cool temperatures for efficient and fast growth.
