Nasturtium belongs to the Tropaeolaceae family, native to South America.
Tropeolo is a genus consisting of about 70-80 species of annual herbaceous plants originating in South America. Tropaeolum majus is the most cultivated species, from which numerous hybrids have been obtained, with erect, creeping or climbing habit.
The plant is perennial in South America, while in Europe, where various hybrid species are grown, it is annual because it particularly fears winter frosts. However, in regions where the climate is milder, in winter the plants can be protected from the cold with mulching: if you have covered them adequately, you will see them flourish in the spring.
The stems of nasturtium they are thin, fleshy, light green; the leaves are round, peltate, waxy, often with a slightly wavy edge. From spring to late summer, cappuccina, another name for Tropaeolum majus, produces numerous fragrant flowers, in shades of yellow and red, with the five sepals united to form a cup-shaped cup, at the back of the flower a short spur stretches. Flowers, leaves and seeds of the nasturtium they are edible and eaten fresh in salads. Remove the faded tropeolo flowers to prolong the flowering.
The beautiful flowers with colors ranging from yellow to orange and red, embellish a garden or a terrace and have a delicate fragrance. It can be grown in the garden for the formation of flower beds, or in the vases, hanging (Tropaeolum minus), or as a climber (Tropaeolum maius) on grids, where it can reach even 2-3 m, depending on the species. It can be planted on slopes or on low walls: it will slide quickly creating a delightful ornament. In fact, the growth of nasturtium is extremely rapid.
Characteristics of Nasturtium
An easy to grow plant that enriches gardens and balconies with flowers of intense and bright colors. Nasturtium is an ornamental, aromatic and medicinal plant, in fact the flowers and leaves are edible and have therapeutic properties.
Extremely appreciated for the vivacity of the colors of its flowers and for the very rich flowering, it is present on balconies and terraces, widespread in gardens or, thanks to its climbing habit, clinging to grids and pergolas. Having no particular needs in terms of soil and care, it is a plant that can cultivate even those who do not have a green thumb.
Nasturtium flowers need a bright and sunny position, the shadow causes little flowering. They should be placed in full sun for best results.
Some varieties cultivated as perennials such as, T. peregrinum, with a yellow flower, and T. speciosum, with a red flower, lose their aerial part in autumn, they must be protected with the use of mulched material in winter, and usually reappear in spring .
These plants usually do not withstand the harsh temperatures and, therefore, are grown as annuals.

The specimens of Tropaeolum majus, also known as the Capuchin, need regular watering, but not too abundant, it is advisable to always keep the soil slightly damp, but not soaked, so check that water does not form. Tropeolo plants can easily withstand short periods of drought. Increase watering on the hottest days of summer.
In winter, for the varieties of nasturtium that are cultivated as perennials, watering should be suspended, until the vegetative restart. Add fertilizer for flowering plants to the water of the watering every 15-20 days.

THE NASTURZIO CALENDAR
March, April and May
|Planting||April and May|
|Flowering||Generally May, June, July August, September, October, but it varies according to species and climate.|
The multiplication of Tropaeolum majus occurs by seed; sow the nasturtiums in February-March, keeping the seedbeds in a sheltered place, before planting the seedlings for a couple of months in individual pots; in May-June they can be sown directly in the open ground.
If the withered flowers come off it is possible to prolong the flowering.
The seeds can be collected and dried. It is possible to preserve and sow them the following year.
Pests and diseases
Capuchin plants are often attacked by aphids and mites that ruin both flowers and leaves. On the market there are numerous varieties of specific products that can be used to protect plants, in the period before flowering; otherwise it is possible to intervene with natural compounds, prepared with water and macerated garlic, or else, a liter of water with a teaspoon of marsiglia soap to be sprayed on the affected specimens.
|Cleaning / Pruning||It is not pruned, the dried leaves and flowers are removed to prolong the flowering.|
|Water needs||Low, but frequent, avoid water stagnation.|
|Multiplication||Sowing, offshoots, cutting|
Tropaeolum maius, a plant with a climbing habit, with roundish leaves and thin and fleshy stems, very delicate, which extend and can reach up to three meters. They climb, they wrap themselves in any support, and cover fences and pylons. The flowers are large and very abundant, they have five petals with colors ranging from red, yellow or orange.
Tropaeolum minus, or nano nasturtium, suitable for pots or small spaces since it grows in the form of small bushes. Red, yellow or orange flowers.
Tropaeolum minus "Peach melba", with yellow flowers, it is ideal to be cultivated in a vase due to its hanging posture. It is used in nutrition, especially for salads.
Tropaeolum peltophorum: similar to the Tropaeolum maius, but with the peduncle of the leaves longer and greyish, and with smaller and orange-scarlet flowers. It blooms from July to October.
Tropaeolum peregrinum or Tropaeolum canariense: perennial species with climbing habit cultivated as an annual. The leaves have five lobes, the flowers are canary yellow with frayed petals. It can reach 3 m. of height.
Tropaeolum polyphyllum: creeping plant. The development in diameter can reach 2 m. In June it produces yellow-orange flowers. Not very suitable for growing in pots because it needs a lot of space to grow.
Tropaeolum speciosum: upright plant, it is especially suitable for places with a mild climate. In summer it produces solitary flowers of an extraordinary bright red, carried by a long peduncle. It reaches 3-5 m. of height. Due to the remarkable root system it is not suitable for cultivation in pots.
Tropaeolum tuberosum: climbing plant with tuberous roots. It reaches 2 m. of height. The leaves are lobed and green-blue in color. It flowers in the August-September period. The yellow flowers outside and red inside are carried by a long flower stem. During the winter it is necessary to protect it from the cold by covering it with straw, or it is necessary to remove the bulbs from the ground in autumn and keep them away from the cold.
In places with mild climate the nasturtium reproduces spontaneously. Otherwise it is possible to sow it in pot in the period March, April or May or directly in the ground in May.
Put in a 3 to 5 seed pot using a soil with peat and sand in equal parts. The vase must be exposed to light, but in a sheltered position so that the temperature does not fall below about 18 degrees. If you place them for example on a veranda, you will have an early flowering. After about two months (in May), when there is no longer the risk of frost, the plants can be planted.
If it is the climbing variety, put them at a distance of 50 cm from each other and provide them with adequate support. For other species 30 cm of distance between one plant and another is sufficient.
If you prefer to sow directly in the garden, you can do it in May.
Seeds produced from the month of July can be harvested, dried and stored so that they can be sown the following year.
Reproduction can also be done by cuttings or offshoots, but in this case it requires some experience. If you prefer the cutting, cut a sprig of 8 cm approximately, plant it in the soil in a sheltered place and protect it with a plastic sheet: the roots will sprout within 8-10 days.
Where to plant it?
