Mizuna is a fast-growing Japanese mustard green with distinctive feathery, serrated leaves and a mild, slightly peppery flavour. It is one of the easiest and fastest Asian greens to grow, ready to harvest as baby leaf in 3-4 weeks. More bolt-resistant than many Asian greens, it can be grown year-round in most Australian zones with successive sowings.
