Brassica rapa var. nipposininca

Mizuna, Brassica rapa var. nipposininca, is a Japanese brassica that is becoming increasingly popular for stir-fries. It's also called Kyona or potherb mustard. Not only is it good to eat, it's also quite decorative, with glossy, serrated, dark green leaves and narrow white stalks, looking good in flower beds and as edging. It's vigorous, adaptable and easy to grow in most soils. Mizuna greens have a mild mustard flavour.

The usual sowing time for Brassica rapa var. nipposininca, outside, is from early to late summer, but it can be sown in late spring or early summer, when it may have a tendency to bolt. Another alternative is to sow in early autumn for transplanting under cover.
