• Mustard greens can be harvested just 30–45 days after sowing, making them one of the fastest-growing leafy vegetables.
• They are exceptionally high in vitamin K, with a single serving providing more than twice the daily recommended value.
• Beyond the kitchen, mustard greens are used as cover crops to suppress weeds and improve soil structure.
• Global production exceeds 2 million metric tons annually, reflecting their widespread demand.

Mustard greens are a nutritional powerhouse. Per 100 grams, they provide approximately 27 kcal, 2.9g protein, 0.4g fat, 4.7g carbohydrates, and 3.2g fiber. They are especially rich in vitamin K (257% daily value), vitamin A (35% DV), and vitamin C (70% DV), alongside folate, calcium, and potent antioxidants. These nutrients support bone health, immune function, and overall wellness.

Mustard greens shine in a variety of culinary contexts. They are enjoyed raw in salads for their spicy bite, cooked in stir-fries and soups, or pickled for tangy side dishes. In Indian cuisine, they are the star of sarson ka saag, while Chinese dishes often feature them pickled or braised. In the Southern United States, they are traditionally simmered with smoked meats. Their versatility makes them a staple in kitchens around the world.

Mustard greens thrive in cool seasons, making spring and autumn ideal for cultivation. They grow rapidly—ready for harvest in 30–45 days—and tolerate mild frost. Optimal yields range from 10 to 25 tons per hectare under good conditions. While moderately resistant to aphids and flea beetles, they are susceptible to downy mildew and white rust. For best results, sow in well-drained soil and harvest promptly to preserve freshness.

• Fresh: Whole or bunched leaves sold at markets and grocery stores.
• Minimally processed: Chopped or bagged leaves for convenience.
• Pickled: Fermented or brined forms, especially popular in East Asian cuisines.

Mustard greens encompass several morphological types, including curly-leaf, flat-leaf, and red-leaf varieties. While specific cultivar names are not widely standardized, regional favorites such as gai choy (Chinese mustard), xuelihong (Mandarin), and sarson (Indian mustard) reflect local preferences and adaptations. Ongoing breeding efforts continue to introduce new cultivars tailored to climate and culinary use.

Growers of mustard greens contend with moderate resistance to aphids and flea beetles but must watch for downy mildew and white rust, which can affect crop health. Integrated pest management and timely harvest are key strategies for minimizing losses and maintaining quality.

Regional naming and use of mustard greens vary widely. In China, varieties like xuelihong and gai choy are popular, often pickled or stir-fried. In India, sarson is a staple in northern cuisine. African and Southern US traditions favor cooked preparations, while Japanese cuisine sometimes includes related greens like mizuna under the mustard greens umbrella. These variations reflect local tastes, cultivars, and culinary heritage.

For optimal quality, select mustard greens with crisp, vibrant leaves free from yellowing or wilting. Store them in the refrigerator, ideally wrapped in a damp cloth or within a perforated bag to retain moisture. Due to their short shelf life, consume fresh or use in pickled preparations soon after purchase. Avoid prolonged storage, as leaves wilt quickly and lose flavor.
