Red Giant Mustard, also known as Japanese Giant Red Mustard, is a traditional Japanese variety of Brassica juncea prized for its deeply pigmented, savoyed foliage. Its dark purple mustard leaves are large, broad, and tinged with reddish-purple tones over vivid chartreuse veins—making them a standout among red mustard greens. This fast-growing, cold-tolerant variety matures in just 30–40 days, with baby red mustard leaves ready to harvest in as few as two weeks. The flavor is bold and spicy with a mustardy heat and faint horseradish undertones, intensifying in warm weather. Young leaves are tender enough for salads, while mature leaves shine in sautés, stir-fries, or pickling recipes. Red Giant Mustard Greens are slow to bolt and perfect for spring and fall gardens. Their vibrant color and rich taste make them a favorite for adding flair to dishes and garden beds alike. Plants reach 12–24 inches tall and grow well in garden beds or containers. Each packet contains a minimum of 500 seeds. Show more
