The large leaves not only make delicious steamed greens, they also make fantastic wraps (a low-calorie substitute for tortillas), and when young, hearty salad greens. Fall frosts make them sweeter, and they may overwinter, as they can survive temperatures down to 20°F. Excellent container variety.. Mature Size: 12-18″ x 12″. Full Sun (6+ Hours).
