Mizuna is vigorous, adaptable and easy to grow in most soils. Leaves have a mild mustard flavour. The usual sowing time, 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.
