Leafy Greens Mustard Red Giant represents a distinguished Japanese heirloom variety celebrated for its impressive size and sophisticated purple-tinted foliage. This popular red mustard cultivar delivers substantial leaf volume with refined aesthetic appeal, making it equally valuable for landscape ornament and culinary applications. The large, purple-tinged leaves create striking visual contrast in garden settings and fresh salad compositions. The deep coloration extends throughout the foliage, providing consistent chromatic interest from multiple viewing angles. The substantial leaf size facilitates efficient harvesting and provides satisfying volume for both fresh and cooked preparations, maximizing productivity from limited garden space. The mild mustard flavor distinguishes Red Giant from more assertive mustard varieties, offering approachable taste without aggressive heat. This balanced flavor profile appeals to diverse palates while maintaining the subtle complexity appreciated by culinary professionals. The tender foliage integrates seamlessly into fresh salads, Asian-inspired preparations, and traditional cooked applications with equal success. Red Giant demonstrates superior performance characteristics compared to related varieties. The plants develop larger overall size, mature slightly later, and display more refined narrow-stemmed architecture. Most significantly, Red Giant exhibits delayed bolting behavior—remaining 3 to 4 days slower to bolt than comparable Osaka Purple varieties—extending the harvest window and providing extended productivity throughout the growing season. The accelerated maturity timeline accommodates flexible harvesting strategies. Baby leaves reach tender, delicate harvestable size in approximately 21 days, ideal for fresh salad applications. Full-sized mature plants develop within 45 days, providing substantial volume for diverse culinary applications and value-added preparations. The reliable germination rate of 70% or better ensures consistent stand establishment and predictable crop performance. Our Non-GMO seeds are sustainably cultivated through practices prioritizing ecological stewardship. The packaging reflects our environmental commitment—designed to be reusable and fully recyclable while reducing climate impact. Choose Leafy Greens Mustard Red Giant for impressive size, refined flavor, and extended harvest windows.
