ABOUT
Red Mizuna is a Japanese mustard green with a character all its own: feathery, deeply serrated leaves emerge green at the cotyledon stage before flushing rich red-purple as they mature under light, creating a tray that looks as striking as it tastes. The flavour is a gentle, clean mustard warmth — less sharp than arugula, more interesting than most salad greens — with a tender, almost silky texture that holds up beautifully in a bowl of miso soup or draped over a plate of smoked salmon. As a member of the Brassica family, it carries the characteristic glucosinolate profile alongside anthocyanins concentrated in those vivid red stems, compounds that only deepen in colour and concentration the longer you allow light exposure. If you want a crop that transforms a plain tray into something worth photographing — and onto a plate in under two weeks — this is it.
