Strongly branching stems of this species of Nasturtium reach a length of 3 m. Flowering occurs from June to September. By the structure of leaves and flowers, the species is similar to Nasturtius large, but surpasses it in its earlier and more abundant flowering. Country of Origin - Colombia.
On sale you can find hybrid forms of this species called Cultural Nasturtium or Hybrid Nasturtium. They bloom earlier, give numerous large flowers, mainly yellow or red. Hybrids are thought to be more sensitive to cold and damp.
Among the popular varieties of Nasturtium shield-bearing, one can note “Ruby” with dark leaves and bright red flowers and “Snow Maiden” with white flowers. Low-growing forms of up to 30 cm are also interesting.
Caring for Nasturtium:
Nasturtiums bloom profusely if they are provided with bright lighting. With a lack of light, flowering will be rare, and the plants themselves will be undecorated because the shoots will begin to “stretch out”.
Nasturtiums are thermophilic. When choosing a place for plants, this factor should be taken into account. Strong winds can damage the fragile, lush shoots of Nasturtium.
Nasturtiums prefer moderately nutritious loose substrates, with good aeration. Plants are sensitive to an excess of nitrogen in the substrate, and in the case of too nutritious soil give a plentiful vegetative mass to the detriment of flowering. You should not plant plants on too dense waterlogged soils.
Before flowering, it is recommended to feed the plants 1-2 times with fertilizers without nitrogen.
Young plants require regular moderate watering. Adult specimens are watered only during long dry and hot weather.
Propagate Nasturtium seeds and cuttings.
Sowing is carried out in May, when the weather is stable and stable. Sown in loose soil, in holes with a depth of 2-3 cm, two or three seeds per hole. Between the holes leave about 20-30 cm. The holes are sprinkled with a loose substrate, moderately watered. Plants emerge within two weeks. It is permissible to sow plants for seedlings in April, in 2-3 seeds in individual containers. When landing in a permanent place, do not break the lump with the root. Plants bloom one and a half to two months after planting seeds. The climbing varieties bloom later than the bushy ones.
In the case of warm, long summers, nasturtium seeds ripen, sometimes the plant propagates by self-sowing.
