Introduction
Nasturtiums are vibrant and versatile plants that not only brighten gardens but also offer a range of culinary and medicinal benefits. Known for their colorful flowers and easy-to-grow nature, Nasturtium flowers are a favorite among gardeners and plant enthusiasts. In this comprehensive guide, we will delve into the world of Nasturtium flowers, exploring their history, varieties, cultivation tips, uses, and much more.
History and Origin of Nasturtiums
Nasturtiums, scientifically known as Tropaeolum, originated in South America, particularly in Peru and Bolivia. The name “nasturtium” comes from the Latin words “nasus” (nose) and “tortus” (twisted), referring to the plant’s pungent smell. Spanish conquistadors brought Nasturtium flowers to Europe in the 16th century, where they quickly gained popularity due to their vibrant colors and edible properties.
Varieties of Nasturtium flowers
Nasturtiums come in various types, each with unique characteristics. The two main species are Tropaeolum majus (common nasturtium) and Tropaeolum minus (dwarf nasturtium). Within these species, there are several popular varieties:
- Empress of India: Known for its deep red flowers and dark green leaves, this compact variety is perfect for borders and containers.
- Alaska: This variety is famous for its variegated leaves and a mix of flower colors, adding a splash of color to any garden.
- Jewel Mix: Featuring semi-double flowers in a range of colors, this variety is ideal for hanging baskets and window boxes.
- Whirlybird Series: Known for its upward-facing flowers in vibrant hues, this series is excellent for adding vertical interest.
Cultivation and Care
Growing nasturtiums is relatively easy, making them a great choice for beginner gardeners. Here are some tips for successful cultivation:
Soil and Location
Nasturtiums prefer well-draining soil with moderate fertility. They thrive in sunny locations but can tolerate partial shade. Avoid overly rich soil, as it can lead to excessive foliage growth at the expense of flowers.
Planting
Nasturtiums can be grown from seeds, which should be sown directly in the garden after the last frost. Soak the seeds in water overnight to enhance germination. Plant the seeds about 1 inch deep and 10-12 inches apart. For a continuous display of flowers, sow seeds every two to three weeks throughout the growing season.
Watering
Nasturtiums are drought-tolerant but perform best with regular watering. Water the plants deeply once or twice a week, allowing the soil to dry out between waterings. Avoid overhead watering to reduce the risk of fungal diseases.
Fertilization
Nasturtiums do not require heavy fertilization. In fact, too much fertilizer can result in lush foliage with few flowers. A light application of a balanced fertilizer at planting time is usually sufficient.
Pest and Disease Control
Nasturtiums are relatively pest-resistant but can occasionally be affected by aphids, caterpillars, and slugs. Regularly inspect the plants and use organic pest control methods, such as neem oil or insecticidal soap, if necessary. Ensure good air circulation around the plants to prevent fungal diseases.
Uses of Nasturtiums
Nasturtium flowers are not only ornamental but also have culinary and medicinal uses. Here are some ways to utilize these versatile plants:
Culinary Uses
- Edible Flowers: Nasturtium flowers are edible and have a peppery flavor, making them a great addition to salads, sandwiches, and garnishes.
- Leaves and Seeds: Both the leaves and seeds of nasturtiums are edible. The leaves can be used in salads or as a substitute for watercress, while the seeds can be pickled and used as a caper substitute.
Medicinal Uses
Nasturtiums have been used in traditional medicine for their antimicrobial and anti-inflammatory properties. They are believed to support respiratory health and boost the immune system. However, it is essential to consult a healthcare professional before using Nasturtium flowers for medicinal purposes.
Companion Planting with Nasturtiums
Nasturtiums are excellent companion plants, attracting beneficial insects and repelling pests. Here are some plants that benefit from being planted alongside Nasturtium flowers:
