Garden Nasturtium (Tropaeolum hybrids)

A very decorative, uncomplicated plant that also thrives in semi-shaded locations and in less than optimal soil. It is often used for fences or grown in pots/buckets as a balcony plant. The base area of a facade can be enhanced with nasturtium, especially under climbing plants that tend to lose leaves near their base. It is also a good choice for interior greening!

(lat.: tropaeolum majus)

Requirements / Suppliers

This easy-to-care-for climbing plant doesn't have any special needs regarding location, but in a sunny and sheltered position will produce more flowers. For rather light and nitrogen-poor garden soils with good drainage; sandy soil is also good. In shade and with damp soil, the plant will form more leaves and fewer flowers. Watering is required in hot and dry weather. Available as seeds, seed blends or in spring, pre-cultivated potted plants.

Characteristics and Pruning

The species in its original form comes from Colombia, Ecuador and Peru, and was introduced in Europe in 1684 by the Dutchman Bewernin. The nasturtium is an annual in Europe and should be sown at the beginning of May. Soak the seeds in water overnight. Alternatively, the seeds can be sprouted in a greenhouse in late winter or indoors in April and then planted in the second half of May. Sow 2-3 grains per planting hole, approx. 2 cm deep, at a distance of approx. 20-30 cm. When sown during summer, the nasturtium can be a beautiful indoor plant that brings colour in the winter months. It can grow up to approx. 3 meters in height. Nasturtium usually climbs as a rambler, sometimes also with leaf-stem tendrils, and with overhanging / cascading growth. This is a colourful and bright plant with flower colours ranging from yellow to red, depending on the variety. The flowering is from June to November. The shoots, young leaves, flowers, and flower buds are all edible. Taking off withered flowers promotes new flower production. Additional measures against aphid infestation are required for indoor culture.

Climbing Aids on Facades

Trellis cables should be placed close together with a 20 - 30 cm wide grid arrangement, or with even narrower nets. Vertical axes should dominate (so, 'standing' rectangles instead of squares). See the bottom of the page for suitable rope trellises. The 5050 shape/design is a solid choice in conjunction with stakes/steel rods. Choose the easy or light or medium version. If the trellis does not reach the ground, the young shoots are led to it with a bamboo stake from the ground. Binding material may be necessary to train the plant upwards.
