In the Garden: Nasturtium is an annual flowering plant native to South America but cultivated worldwide for its edible flowers and leaves, as well as its ornamental value. It prefers full sun and well-drained soil and can tolerate poor soil conditions. Nasturtium produces trailing or climbing stems with round, bright green leaves and vibrant, trumpet-shaped flowers in shades of yellow, orange, red, and pink. It is often grown in flower beds, containers, and hanging baskets or used as a ground cover or companion plant in vegetable gardens to deter pests.
Culinary Uses: Nasturtium flowers and leaves are commonly used in culinary preparations to add color, flavor, and a peppery kick to dishes. The flowers can be used fresh in salads, sandwiches, and garnishes or pickled for use in savory dishes. Nasturtium leaves are edible and can be added to salads or used as a substitute for watercress in recipes. Nasturtium seeds, known as "poor man's capers," can be pickled and used as a condiment.
Precautions: Nasturtium is generally safe for most individuals when consumed in moderate amounts as a culinary herb. However, excessive consumption may cause gastrointestinal upset in some people. Pregnant or breastfeeding women should consult with a healthcare professional before using nasturtium medicinally. Additionally, individuals with certain medical conditions or allergies should use caution when consuming nasturtium.
