Top ornamental plants of nightshade family

Introduction

Do you associate nightshade plants (Solanaceae) only with tasty tomatoes, peppers, potatoes or eggplants? If so, know that it is also worth taking a look at them, taking into account their decorative properties

The nightshade family has nearly 2,500 species present on all continents except the Arctic Circle. Many of the nightshade plants are distinguished by their decorative fruits, flowers and even leaves.

That is why the decorative aspect of species from the Solanaceae family is more and more often used in creating plant arrangements, both in the garden and at home. Nightshades are more and more often grown in home gardens, both as climbers and bedding elements with perennials, or plants for container cultivation, for balconies and terraces.

History of nightshade plants cultivation

The history of the cultivation of nightshade as ornamental plants dates back to ancient times, or more precisely to the ancient Maya and Aztecs, where these plants come from. Originally ripe tomato fruit, tomatillos and sweet peppers constituted an important part of the diet of the inhabitants of South and Central America. They reached Europe in the 15th century, that is, at the time of European colonization. And already 100 years later they were grown as ornamental plants, decorating Italian and Spanish homes.

In the past, people were afraid of the colorful fruit of the tomato and the smell of the plant itself, which scared away potential consumers. Only with time did nightshade vegetables become typical utility plants.

The consumption of nightshades did not develop on a large scale until the 20th century. Nevertheless, cherry tomatoes, annual peppers, plants of the Physalis species or cultivars and hybrids of hot pepper are still cultivated for their colorful fruits of various sizes and shapes, and for the bellows protecting the berries. Other species with decorative flowers, shoots and leaves are part of floral arrangements such as bouquets, table decorations, windows, flower wreaths and dry arrangements.

Decorative nature of plants from the Solanaceae family

The decorative character of plants from the nightshade family is mainly determined by colorful fruits of various shapes and sizes. Examples of plants commonly used in cultivation for their colorful berries are poisonous nightshades, as well as varieties and cultivars of hot pepper and annual pepper.

Decorative fruit and follicles of nightshade plants

Plants belonging to the genus Physalis L. are characterized by original follicles that cover the berry (fruit) inside them. During the development of the fruit in the bellows, the calyx sepals gradually expand, which cover the fruit that is formed inside them. Decorative bellows can be used to create floral arrangements and as an element of dry bouquets.

In turn, such species of nightshade as tomato, pepper, eggplant produce not only tasty but also colorful fruits of various sizes and shapes. Such plants, commonly classified as vegetables, can be grown together with other ornamental plants on a mixed bed or used in container plantings.

Colorful flowers of nightshade plants

Nightshade plants are also plants with decorative flowers. An example is the garden petunia, jasmine tobacco or blue potatobush (Lycianthes rantonnetii), known as the "sapphire storm" is an excellent example of a species of the nightshade family with ornamental flowers. Lycianthes rantonnetii is called a sapphire storm because of the purple-blue flowers that cover the plant This plant comes from Latin America and in the climatic conditions of Poland it is grown only as a potted plant. In addition to the blue-flowered varieties, the cultivation also includes white-blooming varieties.

Decorative leaves and shoots of nightshade plants

Some species of nightshade produce decorative leaves and shoots, such as coral nightshade of 'Variegata' with white-green leaves and annual peppers of 'Purple Tiger Variegata', which are characterized by purple-white-green leaves. In turn, long and slender shoots produced by jasmine nightshade determine its decorative character and use as an ornamental creeper from the nightshade family.

How to exhibit a decoration made of nightshade plants?

Decorations made of nightshade plants can be made almost all year round. These plants look especially attractive in summer.

On the other hand, plants with hanging shoots, such as cascade petunias, will look best when planted in hanging baskets.

Pots with decorative peppers and nightshades grown at home should be placed on a balcony or terrace in summer. In winter, in turn, plants should be protected from the cold and grown at home, preferably on a light window sill, depending on the climate zone.

Plants from the nightshade family are an interesting decoration of the house, garden and balcony. It is worth remembering that most of the species in this family are poisonous. Therefore, if you want to create a colorful and interesting composition, remember to place it out of the reach of animals and small children who could eat some of the plant or fruit.

Are nightshades toxic?

Almost all plant species belonging to the Solanaceae family have poisonous compounds - glycoalkaloids. The most popular alkaloids found in nightshade plants are tomatin and solanine. According to many studies, their primary task is to protect plants against pests, as evidenced by the accumulation of these compounds in damaged potato tissues.

Glycoalkaloids are present in all organs of nightshade plants, from the root through the stem, leaves, flowers and unripe fruit. It has been suggested that light is the factor inducing the occurrence of glycoalkaloids. Both the content of tomatin and solanine in plants depends on the species, variety, cultivation method and position, as well as the physiological condition of the plant. Tomatin has a toxic effect similar to solanine, but is less poisonous. Numerous studies conducted on mice indicate that the lethal dose of tomatin is 1000 mg per kg of body weight. Unripe fruit of edible tomato can cause poisoning in humans and animals. Therefore when consuming mixtures, preserves and pickles made of 'green tomatoes', one should choose only those fruits that have already reached the stage of 'already grown green fruit'.

When creating seasonal decorations with hot pepper fruits, it is worth paying attention to its use and the position in which it will be exhibited. Arrangements with hot peppers should be avoided in rooms where small children and animals will come into direct contact with them. The spiciness of the pepper fruit is evidenced by the content of the alkaloid - capsaicin, the content of which is closely related to the variety and the stage of plant development. It is most abundant in the placental tissue that supports the seed. From there, it penetrates into other tissues of the fruit, giving it a specific spicy taste. The presence of capsaicin is due to the protection of plants against herbivores and fungi.

Summary

Species belonging to the Solanaceae family are not only popular utility plants such as tomatoes and peppers. They are also ornamental plants that are grown for beautiful flowers, colorful bags and interesting shoots. There are many ways to use nightshades. Each element of the plant can be used in floristry and bouquet making. However, the decorative follicles of Physalis species deserve special attention, as they can be used both for live and dry flower arrangements, both seasonal and occasional.

On the other hand, garden petunias or painted tongue can be used to create colorful plantings decorating balconies and terraces, and to plant baskets and pots in season. There are many possibilities of decorative use of nightshades, but remember to be especially careful in rooms and facilities where both children and animals may come into direct contact with these beautiful plants.
