Sea kale (Crambe maritima) is a perennial plant found on coastlines, easily recognized by its bluish-green, wavy leaves. π It's a member of the cabbage family and has a slightly bitter, cabbage-like flavor. Think of it as the ocean's leafy green β a wild, coastal vegetable. It's like the free-spirited cousin of your grocery store kale. Unlike cultivated kale, it grows wild and free on beaches and cliffs.
