Nasturtium Varieties

Nasturtiums come in a variety of species that offer a range of flower colors, leaf shapes, and growth habits. The most common types include the trailing varieties, which are perfect for hanging baskets or climbing trellises, and the compact bush varieties, ideal for border displays and container gardening. The vibrant colors of the flowers, ranging from bright yellows and oranges to deep reds, make them a popular choice among gardeners looking to add a splash of color to their gardens.

Two of the most popular species are Tropaeolum majus and Tropaeolum minus. Tropaeolum majus is known for its larger flowers and vigorous growth, making it perfect for covering large areas quickly. Tropaeolum minus, on the other hand, has smaller flowers and a more refined growth, suitable for those who prefer a more contained plant. Both species are equally beautiful and provide great aesthetic value and functional benefits.

How to Plant Nasturtium Seeds

Choosing the Right Time and Place

Timing is crucial when planting nasturtium seeds. The best time to plant them is after the last frost date in your area. This ensures that the seeds can germinate and grow without the risk of cold damage. Nasturtiums thrive in full sun, so choose a location in your garden that receives ample sunlight throughout the day. They can tolerate partial shade, but full sun will produce the best blooms.

Nasturtiums prefer well-draining soil, although they are quite forgiving of poor soil conditions as long as it’s not too rich. Overly fertile soil can lead to lush foliage at the expense of flowers. If your soil is nutrient-rich, consider amending it with sand or another well-draining substance to create the perfect environment for your nasturtiums.

How to Care for Nasturtiums

Nasturtiums are known for their hardiness and ease of care, which makes them a favorite among gardeners. Once planted, they require minimal maintenance. Water them regularly, especially during dry spells, but be careful not to over-water, as nasturtiums prefer relatively dry conditions.

Prune nasturtiums by removing spent flowers or damaged foliage to encourage further blooming and maintain a tidy appearance. Regular deadheading will also prevent the plants from self-seeding excessively, which can lead to overcrowding. With these simple care steps, your nasturtiums will thrive all season long, providing continuous color and interest in your garden.

Nasturtiums are Edible

One of the most exciting aspects of growing nasturtiums is their edibility. Both the leaves and flowers are edible and add a peppery flavor reminiscent of arugula. They make a delightful addition to salads and can be used as garnishes for a colorful and flavorful touch.

Nasturtium seeds can be pickled, and when prepared correctly, become a tangy substitute for capers. This unique culinary use of nasturtiums extends their value beyond the garden, making them a versatile and functional plant to grow.

Nasturtiums as a Pest Deterrent

Nasturtiums serve as a natural pest deterrent, attracting pests away from other plants in your garden. They are particularly effective at deterring aphids, whiteflies, and squash bugs, making them a great companion plant for vegetables and other susceptible plants.

Their ability to attract beneficial insects like bees and ladybugs further enhances their value in integrated pest management strategies. Planting nasturtiums in strategic locations throughout your garden can reduce the need for chemical pesticides and promote a healthier garden ecosystem.

Companion Plants for Nasturtiums

Nasturtiums are excellent companion plants that benefit a wide range of other plants with their ability to repel pests. They partner well with vegetables such as tomatoes, cucumbers, and pumpkins, offering natural protection by drawing pests away from these crops.

Additionally, nasturtiums can enhance the growth of other plants by improving soil health and attracting pollinators. Their bright flowers and attractive foliage add visual appeal, making them a charming addition to any companion planting scheme.

Saving Nasturtium Seeds

Saving nasturtium seeds is a rewarding process that ensures you have a continual supply of seeds for the next planting season. After the flowering period, allow some seed pods to dry on the plant until they turn brown. This is the perfect time to collect them.

Once harvested, spread the seeds out on a flat surface in a dry, cool place to thoroughly dry. Store them in a labeled envelope or airtight container until you are ready to plant them the following year. Saving your seeds not only preserves your favorite varieties but also helps you sustain your garden at a minimal cost.
