Wasabina mustard green is a Japanese brassica that brings a delicate, peppery bite to the garden with surprising speed. Ready to harvest in just 21 days, this open-pollinated variety grows as a compact bush, making it excellent for containers or quick succession planting. The leaves are tender and lofty with a mild, wasabi-like flavor that mellows as plants mature, offering both raw crunch and cooked depth depending on your mood and the season.

At 21 days to harvest, Wasabina delivers tender, unusually mild mustard leaves faster than almost any green in the brassica family. The lofty growth habit gives it an airy, almost delicate appearance despite its peppery heritage, and the flavor strikes an interesting balance between the sharpness you'd expect from mustard and a surprising gentleness that makes it approachable even for heat-sensitive palates. Because it tolerates cool-season growing so well, you can stretch your harvest window from early spring through late fall, even into winter with high tunnel protection.
Wasabina shines as a fresh salad green where its tender texture becomes the main event, though it also holds up beautifully in quick stir-fries and warm bowls. The mild peppery kick works as a sophisticated contrast to rich proteins or creamy dressings, and because the leaves stay tender even at mature size, you can harvest full-sized leaves for cooking without the tough, fibrous texture that stops you from eating mature mustard greens raw.

Sow seeds directly into prepared garden beds or containers after the danger of heavy frost has passed in spring, or 8 to 10 weeks before your first expected fall frost for a cool-season crop. Seeds germinate reliably in cool to moderate temperatures typical of spring and fall gardening.
Begin harvesting when leaves reach 3 to 6 inches long by cutting with a knife just above the basal plate, allowing the plant to regenerate for repeated harvests. Depending on variety and season, you can make successive cuts every 5 to 14 days as new leaves reach your desired size. This cut-and-come-again approach extends your harvest window from a single planting considerably.
