Kale is the toughest and most productive leafy green brassica, available in curly, flat (Tuscan/cavolo nero), and red Russian forms. It tolerates frost (which sweetens its flavour), handles some heat, and produces for 6-12 months with regular harvesting. A nutritional powerhouse and genuinely easy to grow compared to heading brassicas.
