Nasturtiums are a versatile, vibrant, and highly beneficial addition to any backyard garden. Known for their beautiful blooms in shades of orange, yellow, and red, these plants not only add color and charm to your outdoor space but also offer a range of practical uses. From natural pest control to attracting pollinators, nasturtiums are an easy-to-grow, edible plant that brings value to gardens of all sizes. Let’s explore why nasturtiums are a must-have and how you can use every part of this remarkable plant.

Benefits of Growing Nasturtiums in Your Backyard

1. Pest Control: A Natural Solution for Garden Health

Nasturtiums act as a “trap crop,” meaning they attract pests like aphids, caterpillars, and whiteflies, diverting these harmful insects away from your more delicate plants. This makes nasturtiums an excellent companion for vegetables like tomatoes, cucumbers, and peppers. By planting nasturtiums nearby, you’re creating a natural defense system in your garden, reducing the need for chemical pesticides.

2. Attracts Pollinators: A Boost for Garden Productivity

Nasturtiums are loved by bees, butterflies, and beneficial insects due to their bright, eye-catching flowers. Pollinators are essential for the reproduction of many plants, including fruits and vegetables. By attracting these helpful creatures to your garden, nasturtiums contribute to better pollination and, consequently, increased yields from plants like squash, zucchini, and berries.

3. Easy to Grow: Low-Maintenance and Resilient

One of the greatest things about nasturtiums is their resilience and ability to thrive in poor soil conditions. In fact, they often do better in low-nutrient soil where other plants might struggle. This makes them a fantastic choice for gardeners seeking low-maintenance plants. Nasturtiums are drought-tolerant and grow quickly, spreading through your garden with minimal effort. They require only occasional watering and will even flourish in container gardens or hanging baskets.

4. Edible and Delicious: A Unique Ingredient for Creative Cooking

Every part of the nasturtium plant—flowers, leaves, and seeds—is edible, adding a unique, peppery flavor that can enhance a variety of dishes. The flowers, with their bright colors and delicate texture, are perfect for salads, while the leaves can be used in a range of savory applications. The seeds, when pickled, make a flavorful substitute for capers. This makes nasturtiums an ideal choice for gardeners who enjoy experimenting with fresh ingredients in their cooking.

How to Use Every Part of the Nasturtium Plant

Each part of the nasturtium plant has its own unique taste and culinary application. Here’s a guide to incorporating nasturtium flowers, leaves, and seeds into your meals.

1. Flowers

• Taste: The flowers have a mild peppery flavor, similar to arugula, which adds a refreshing bite to dishes.
• How to Use:
  • Add flowers to salads for a pop of color and spice.
  • Use as a garnish for appetizers, soups, and main dishes.
  • Stuff the flowers with soft cheeses like goat cheese or ricotta for a visually stunning and flavorful appetizer.

2. Leaves

• Taste: Nasturtium leaves are spicy and peppery, making them perfect for enhancing savory dishes.
• How to Use:
  • Use fresh leaves in salads, sandwiches, and wraps to add a zesty bite.
  • Blend the leaves into pesto, adding an extra peppery kick that pairs well with pasta or grilled vegetables.
  • Mix them into omelets or frittatas for an herbaceous, slightly spicy flavor.

3. Seeds

• Taste: The green seeds are tangy, with a taste similar to capers.
• How to Use:
  • Pickle the unripe seeds to create “poor man’s capers” for use in salads, sauces, or as a condiment.
  • Add the seeds to marinades for meats or vegetables for an extra layer of flavor.

Growing and Caring for Nasturtiums

Nasturtiums are one of the easiest plants to grow, making them perfect for beginners and seasoned gardeners alike.

Planting

• When to Plant: Plant nasturtium seeds in the spring after the last frost, or start them indoors a few weeks earlier to get a jumpstart on the growing season.
• Soil: They do best in poor or well-draining soil, as high nutrient levels can lead to excessive foliage and fewer flowers.
• Sunlight: While nasturtiums can tolerate some shade, they prefer full sun for optimal growth and flower production.

Watering

• Frequency: Nasturtiums are drought-tolerant once established, so water them sparingly. Overwatering can lead to root rot, so ensure the soil is slightly dry before watering again.

Maintenance

• Pruning: Prune the plants lightly to control growth and encourage bushier plants with more flowers. Remove spent flowers to encourage further blooming.
• Pests and Disease: Nasturtiums are generally pest-resistant; however, they may attract aphids. If aphids become a problem, simply spray the plant with a strong stream of water to dislodge them.

Harvesting

• Flowers: Pick the flowers when they are fully open but still fresh. The flowers are best used immediately but can be stored in the fridge for a day or two.
• Leaves: Harvest young leaves for a milder flavor. Leaves can be used immediately or stored in the fridge for up to a week.
• Seeds: Harvest green seeds while they’re still tender, or allow them to dry on the plant if you plan to use them as a spice.
