Mizuna seeds

The elegant Japanese green worth a spot in your garden

Mizuna (Brassica rapa var. nipposinica) is a Japanese mustard green grown for its feathery, deeply serrated leaves and gentle, peppery flavor. Milder than arugula or true mustard, it delivers a fresh, mustardy zip without overwhelming a salad, and its lacy foliage looks as good in the garden as it does on the plate. Fast, cold-tolerant, and quick to regrow after cutting, mizuna is one of the most rewarding baby greens you can raise for salads and stir-fries alike.

How to grow mizuna from seed

Mizuna is easy and quick from seed. Sow mizuna seeds about a quarter inch deep in full sun to part shade in cool weather, spring or fall, then thin seedlings to stand a few inches apart for full heads or grow them thick as baby greens. Leaves are ready to cut as baby greens in about 20 to 25 days and as mature plants in 40 days, and they regrow for repeated cut-and-come-again harvests. It tolerates light frost well.

How to use mizuna

Young mizuna leaves are excellent raw, adding a mild, peppery lift and lacy texture to salad mixes and sandwiches. More mature leaves are delicious lightly cooked; they wilt quickly into stir-fries, soups, and noodle bowls, and they hold up in a hot pan better than tender lettuces. Mizuna is a staple of Japanese cooking and a natural in Asian-inspired slaws and pickles.
