This is a new type of Japanese all-season green resulting from a cross between Komatsuna and Tatsoi. The two varieties we offer have been cultivated to tolerate high temperatures. The dark glossy leaves are as nutritious as they look, and they are ideal for pickling, which is how they are typically prepared in China. Throughout Japan and China, the greens are also used in stir-fries and other dishes. Leaves intensify in flavor as they mature.
