Ruby Streaks Mustard, Heirloom Seeds

Ruby Streaks Mustard, Heirloom Seeds — The Chef's Favorite With Intricately Lobed Leaves and Mild Sweet Flavor

Ruby Streaks (Brassica juncea) is the mustard green that chefs reach for when they want both flavor and visual drama. Intricately lobed, deeply serrated leaves range from dark green with purple veining to deep maroon — the color deepening beautifully in cooler weather. The flavor is mild, sweet, and slightly peppery: approachable enough for fresh salads, satisfying enough for stir-fries and braising. Even the flower buds and bright yellow blossoms offer a tangy accent. Ruby Streaks grows quickly, tolerates heat better than many greens, and adds striking color, texture, and loft to any dish. A favorite among chefs and market growers for its rosy elegance. Baby leaves in 20 days, full maturity at 40–45 days.
