Red Giant Mustard Green is a broadleaf mustard that delivers impressive speed to the table, reaching harvestable size in just 21 days. This open-pollinated variety from Brassica juncea grows as a compact bush and develops those characteristic large, deeply savoyed leaves with striking red coloring that makes it as beautiful in the garden as it is on the plate. Because it resists bolting even when temperatures warm, you'll get reliable harvests throughout the season, and the cut-and-come-again growth habit means a single planting produces multiple pickings.

The real strength of Red Giant lies in its patience with heat. Most mustard greens rush to flower the moment temperatures climb, but this variety stays focused on leaf production, giving you a genuinely extended harvest window. The slow-bolting character combined with fast maturity (21 days) means you can succession plant every three weeks and maintain a steady supply without racing against the calendar. Those broad, deeply textured leaves are both visually striking and substantial enough to hold up to cooking or stand confidently in a salad.
Red Giant Mustard Green is primarily grown for its edible leaves, which can be harvested young and tender for raw salads or allowed to reach full size for cooking. The large, savoyed foliage holds up well to heat and takes on a milder, almost sweet character when cooked. It works beautifully in stir-fries, braises, and wilted greens dishes where the substantial leaf structure resists turning to mush.

Direct sow seeds where you want them to grow, as brassicas generally transplant well but can be seeded in place. Time sowings from early spring through late summer for continuous harvest, adjusting for your local growing season.
Begin harvesting when outer leaves reach approximately 3 to 6 inches long, using a sharp knife to cut above the basal plate. This technique allows the plant to continue producing new leaves for repeated harvests every 5 to 14 days, depending on weather and season. The cut-and-come-again method works best with Red Giant because of its strong regrowth capability. You can take a few outer leaves for immediate use or harvest the entire above-ground plant if you prefer; just leave the growing center intact for regeneration.
