Leafy greens are plants consumed regularly for vitamins, minerals, and nutrients absent from starchy staples like grains and roots. These vegetables addressed nutritional deficiencies that caused disease when populations relied solely on calorie-dense crops. Many grow quickly, regenerate after harvest, and thrive in marginal conditions. This collection includes both cultivated vegetables and foraged wild plants that once formed the foundation of daily nutrition.
