Yes, you can eat nasturtium leaves. In fact, all parts of the nasturtium plant, including leaves, stems, flowers, and young seed pods, are edible and commonly used in cuisine. Both small and large leaves are safe to eat, with young leaves generally being more tender, while older ones can become tougher later in the season. Nasturtium leaves offer a peppery, slightly bitter taste, somewhat similar to watercress or radishes, making them a flavorful addition to salads, soups, pesto, and other recipes[1][3][5].
All varieties of nasturtium are edible, and the plant is not considered poisonous to people. However, caution is advised for those with sensitivities or allergies, as nasturtium leaves contain glucosinolates—compounds responsible for their spicy flavor—which can irritate the digestive tract or skin in sensitive individuals, especially if consumed in large quantities[2]. Generally, when eaten in normal dietary amounts, nasturtium leaves are regarded as safe for most adults[6].
Nasturtium leaves can be enjoyed raw in salads or cooked as a green vegetable. Larger leaves can even be used as wraps, similar to how grape leaves are used. When cooked, the leaves lose some of their peppery bite and develop a soft, buttery texture[5][3].
Potential adverse effects are uncommon but may include stomach upset or kidney irritation, especially with excessive consumption or in those with preexisting conditions like kidney disease. Children and pregnant or breastfeeding women should consult a healthcare provider before consuming nasturtium, as safety data are insufficient for these groups[6].
