Early Mizuna Mustard Seeds | Japanese Kyona Heirloom | Non-GMO | Baby Greens in 21 Days

Japan’s Most Beloved Salad Mustard — Fast, Prolific, and Endlessly Versatile

Early Mizuna (Brassica rapa Japonica group) is a Japanese heirloom mustard originating in the Kyoto region, where it has been grown for centuries as Kyona — a cornerstone of traditional Japanese cuisine. Our selection is a true Kyoto/Kyona type: long, slender stems with deeply serrated dark green leaves, a mild peppery flavor that sweetens with cold, and vigorous multi-branching growth that’s perfect for cut-and-come-again harvesting. Heat-tolerant, cold-tolerant, slow to bolt — one of the hardest-working greens in any garden.

In the Kitchen

Mizuna is a staple in Japanese salads, sukiyaki, shabu-shabu, yosenabe, ohitashi, and hariharinabe. Its mild, slightly peppery bite makes it a superb raw salad green and an excellent substitute for kale or mustard greens. Try it tossed with fried tofu and a zesty sesame dressing — a Japanese classic. Also outstanding in stir-fries, soups, and pickled preparations.

Growing Guide

• Sow: Spring after last frost, or mid-to-late summer for fall harvest
• Temperature: Mid 40s°F ideal for early growth; near 70°F for later growth
• Succession plant every few weeks for a continuous harvest all season
• Water at ground level if possible; keep soil consistently moist
• Shade partially in summer heat for fall harvests
• Harvest: Lower branches for ongoing production, or cut the entire plant
• Microgreens: Harvest at 3–4" for the most tender, mild leaves
