The defining trait here is the spice level, these leaves deliver a genuine wasabi intensity that transforms simple stir-fries into something memorable. Large, wrinkled fan-shaped leaves grow on sturdy stalks from a vigorous, compact plant, and the variety's heat tolerance means you can keep harvesting through warmer months when typical greens fade. For gardeners seeking authentic flavor over delicate tenderness, this heirloom performs exactly as it has for generations in Asian kitchens.
The primary use is fresh in stir-fries and cooked Asian dishes where the spicy bite becomes a flavor anchor rather than a side note. The large stalks are tender enough to eat alongside the leaves, making the whole plant useful. These greens also work well in pickled preparations where the heat level complements acidic flavors, and they can be incorporated into soups and braises where their peppery character enriches broths.
No timeline data available yet for this variety.
Direct sow seeds in spring 2-3 weeks before the last spring frost, or in late summer 8-10 weeks before the first fall frost. Sow in rows spaced 18 inches apart, with individual seeds 6 inches apart. The variety's heat tolerance means early summer sowings can work as well, giving you multiple planting windows.
Begin harvesting 30-39 days after sowing once leaves reach usable size and show the characteristic wrinkled texture. You can harvest individual outer leaves once the plant establishes itself, or cut the entire plant at soil level for a single heavy yield. The large stalks are ready when still tender; they toughen as the plant matures in heat. Harvest in the morning for the crispest leaves and strongest flavor. The frost-tolerant nature means you can continue harvesting well into fall, even after light frosts.
