Mizuna Mustard Greens, Heirloom Seeds

Mizuna Mustard Greens, Heirloom Seeds — The Fast-Growing Japanese Green That Outperforms Lettuce in Heat

Mizuna (Brassica rapa var. japonica) is the Japanese mustard green that belongs in every salad garden. Dandelion-like jagged-edged leaves with a mild, sweet, earthy flavor — noticeably milder than other mustard greens — make Mizuna the perfect gateway into Asian greens. It grows faster than almost anything else in the cool-season garden, withstands heat longer than lettuce, and is slow to bolt. A true cut-and-come-again plant that keeps producing all season. Harvest baby greens in just 10 days, tender full leaves at 30 days, or use as a microgreen for a harvest in under a week. Excellent raw in salads, wilted in stir-fries, or added to soups. Seeds germinate readily even in cold, wet spring conditions.

Why Grow Mizuna?

• Faster than lettuce — baby greens in 10 days, full leaves in 30 days
• Heat tolerant and slow to bolt — outperforms lettuce in warm weather
• Cut-and-come-again — harvest outer leaves or cut the whole head, it keeps producing
• Outstanding microgreen — fast, flavorful, and beautiful
• Open-pollinated heirloom — save seed year after year

Growing Notes

Direct sow outdoors 4–6 weeks before last frost or in late summer for fall harvest. Sow seeds ¼ inch deep, 1–2 inches apart. Thin to 6 inches for full plants. Germinates readily in cold, wet conditions. Full sun to part shade — shade extends harvest in warm weather. Water consistently. Harvest outer leaves continuously or cut whole plant at soil level for baby greens.
