(40 days) F-1 hybrid. Developed in Japan, a cross between Komatsuna (Japanese Mustard Spinach Brassica rapa) and regular cabbage. “Customers buy it once because it looks absolutely stunning, then they buy it again because it is extremely delicious. Absurdly productive and easy to grow,” raves John Eisenstein of Port Royal, Pa. Round medium-green leaves are wonderful in okonamiyaki or for braising. A spring sowing will stand the entire summer (even through drought) and well into fall before bolting. Can be overwintered in warmer climes or used for spring greenhouse salad production because it grows so rapidly. Open plant habit requires 12–18" spacing. 20,600 seeds/oz. Cold-hardy through at least part of the Maine winter.⑤
