In this article, we explore everything you need to know about nasturtium, from its origins and production to its culinary uses and storage.

What Is Nasturtium?

Nasturtium (Tropaeolum majus) is a flowering plant native to South America, particularly Peru and Chile. Belonging to the family Tropaeolaceae, it is characterized by its bright orange, red, or yellow flowers and round, shield-like leaves. Not only celebrated for its ornamental beauty, nasturtium has been used as a culinary ingredient for centuries, prized for its distinct peppery flavor reminiscent of arugula or mustard greens. Both its leaves and flowers are edible, making it a popular choice in salads and as a garnish.

History and Origins

The history of nasturtium dates back to the pre-Columbian era when indigenous peoples of South America utilized the plant for both culinary and medicinal purposes. The Spanish Conquistadors were among the first Europeans to encounter nasturtium, bringing the plant back to Europe in the 16th century. Once introduced, it quickly gained popularity, especially in France and England, where it was cultivated not only for its culinary value but also for its decorative appeal in gardens.

By the 18th century, nasturtium had become a staple in European cuisine, particularly in salads and as a garnish. Its ability to thrive in various climates has aided its spread across the globe, allowing it to be integrated into different culinary traditions. Today, it is cultivated widely, from home gardens to commercial farms, and is appreciated for its both aesthetic and gastronomic contributions.

Production and Processing

Nasturtiums are typically grown in temperate climates and thrive in well-drained soil with moderate sunlight. They can be cultivated from seed or transplants, with seeds being sown directly into the ground or started indoors. The plant is relatively low-maintenance, requiring minimal care aside from regular watering and occasional fertilization.

Once harvested, nasturtium leaves and flowers are typically used fresh to maintain their crisp texture and flavor. They are often rinsed gently and dried before being packaged or sold in markets. In some cases, nasturtium may be preserved through pickling, a method that enhances its flavor profile while extending shelf life.

Quality and Grading

When assessing the quality of nasturtium, several factors come into play, including freshness, color, and flavor. High-quality nasturtium should exhibit vibrant colors, whether deep orange, rich red, or bright yellow, and have a crisp texture. The leaves should be free from wilting or discoloration, indicating freshness.

Grading for commercial purposes may not be as formalized as for other ingredients, but buyers should look for local suppliers who prioritize sustainability and freshness. Organic nasturtium is often preferred, as it is cultivated without synthetic pesticides or fertilizers, ensuring a cleaner product.

Buying Considerations

When purchasing nasturtium, consider the following factors:

1. Freshness: Look for bright, crisp leaves and vibrant flowers. Avoid wilted or discolored specimens.

2. Source: Opt for local or organic suppliers to ensure the best quality and support sustainable practices.

3. Seasonality: Nasturtium is typically available in the warmer months, so plan your purchases accordingly to enjoy it at its best.

4. Presentation: For garnishing purposes, choose nasturtium flowers that are fully open and visually appealing.

5. Storage: If buying in bulk, understand storage recommendations to maintain freshness.

Uses and Applications

Nasturtium is celebrated for its culinary versatility. Its leaves can be used fresh in salads, offering a peppery kick that complements a variety of ingredients. The flowers, often utilized for their aesthetic appeal, can serve as colorful garnishes or flavor enhancers in dishes.

Beyond salads, nasturtium can be infused in oils or vinegars, adding a unique flavor dimension to dressings and marinades. Additionally, the plant’s edible properties make it a popular choice in various cuisines, from European to Asian, where it is incorporated into soups, sandwiches, and more.

Nasturtium is also gaining recognition in the beverage world, where its flavor can be used to infuse cocktails or even herbal teas, providing an inventive twist to traditional ingredients.

To maintain crispness, keep them in a breathable container or wrap them in a damp paper towel within a plastic bag.

When stored properly, nasturtium can last for about a week, although it is best consumed fresh for optimal flavor and texture. If you need to preserve it for longer periods, consider pickling or freezing the leaves and flowers, although this may alter their texture.
