What Are Nasturtiums?

Table of Contents

Nasturtiums, botanically known as Tropaeolum spp., are fast-growing herbaceous plants native to the Andes Mountains of Bolivia, Columbia, and Peru. These vibrant flowers feature trumpet-shaped blooms in an array of tropical shades, surrounded by round, jade-green leaves. Nasturtiums are commonly grown in home gardens and are popular for their easy cultivation and striking appearance.

Cultivation and History

The history of nasturtiums dates back to the 16th and 17th centuries when seeds of Tropaeolum minus were brought to Europe by the conquistadors. These plants quickly gained popularity for their culinary and ornamental uses. Over the years, different species of nasturtiums have been introduced, with T. majus, T. minus, T. peregrinum, and T. speciosum being among the most popular ornamentals.

Nasturtium Plant Propagation

Nasturtiums can be propagated from seeds or stem cuttings. When starting from seed, it’s essential to nick the thick seed coat to aid germination. Direct sowing is the preferred method, but seeds can also be started indoors. Stem cuttings can be taken in spring and rooted in a light potting mix to develop new plants.

How to Grow Nasturtium Flowers

Growing nasturtiums is relatively simple, requiring full sun and well-draining, poor soil. These plants thrive in neutral soil with minimal fertilizer requirements. Regular watering and mulching are recommended, and established plants can tolerate periods of drought and high temperatures. For container-grown nasturtiums, a balanced or low-nitrogen fertilizer can be applied in late spring.

Growing Tips

Use biodegradable pots for seed starting to prevent root shock.
Nasturtiums prefer poor soil and minimal fertilization.
Provide vertical support for climbing varieties.
For abundant foliage, plant in partial shade.

Pruning and Maintenance

Regular grooming and deadheading can help promote new flower growth in nasturtiums. Pruning back lanky stems can also encourage new growth and ensure a tidy appearance. Climbing varieties may require support, such as trellises or netting. Container-grown plants benefit from occasional trimming to maintain shape and flower production.

Nasturtium Cultivars to Select

There are several cultivars of nasturtiums available for home gardeners, each offering unique flower colors and habits. Popular options include ‘Alaska,’ ‘Empress of India,’ ‘Jewel,’ ‘Moonlight,’ and ‘Spitfire.’ These varieties come in a range of colors and growth habits, making them suitable for various garden settings.

Managing Pests and Disease

While nasturtiums are relatively disease-free, they may be susceptible to pests such as aphids, cabbage loopers, leafhoppers, and leafminers. Proper pest control measures, including handpicking and the use of insecticidal soap, can help manage infestations. Common diseases such as aster yellows, clubroot, mosaic virus, and wilt may also affect nasturtiums. Identifying and promptly addressing these issues is essential to maintain plant health.

Harvesting Nasturtium Flowers

Nasturtium flowers and leaves can be harvested throughout the growing season for culinary use. Flowers can be used as a garnish, added to salads, or pickled for a tangy treat. Harvesting seed pods while green and tender allows for pickling and culinary experimentation.
