The flowers resistant to the sun

Sun-resistant flowers: geranium

Among the sun-resistant flowers it is impossible to ignore geranium. Belonging to the genus Pelargonium, geranium is native to South Africa, and includes over a hundred species. The best known and most cultivated are about thirty, together with numerous cultivars and hybrids produced artificially. Beautiful to look at, geraniums are sun-resistant flowersand to winter weather, thus adapting to cultivation in exposed areas. There are many varieties that can be easily grown on the terrace, among which we remember the Parisian geranium, with bundles of leaves and flowers that fall downwards, or the zonale Pelargonium, also called common geranium, which resists temperatures above 35 degrees and not. is affected by direct sunlight. The colors vary from pure white to pink, passing through bright red, orange, salmon, yellow and purple. Still not very common but quite well known, is the genetically modified “black form” geranium: its flowers are velvety, with the black center that gradually lightens towards purple.

The Buddleja

Also known as the “butterfly tree”, the Buddleja genus includes about one hundred species of herbaceous or arboreal plants, spread all over the world. The most common on the market is the Buddleja davidii, used for the construction of hedges, borders and escarpments in city parks or private gardens. The flowers of this plant are small and vary from white to pale purple, through light blue and sky blue. They are collected in refined, incredibly fragrant panicle inflorescences, which in spring and summer attract a huge variety of insects, especially the butterflies of the genus Vanessa and Papilio. All Buddleja do not require excessive care and many species adapt to life in pots and on the terrace, making them very resistant to direct sunlight. Rather,


The genus Petunia, native to Brazil, is decidedly small, and includes only seven species of herbaceous plants, especially appreciated for their large and colorful flowers. Their import and diffusion worldwide, has allowed the propagation of varieties, hybrids and cultivars so numerous, that it is nowadays difficult to distinguish them from the original species. They are very resistant to the sun and bad weather, and their rusticity allows an optimal cultivation both on the terrace and in the garden. Petunia flowers are trombiform, with petals joined and welded together to recreate a single soft and silky corolla, with the most disparate colors and combinations: purple and white, fuchsia and red, blue and white and so on, and not infrequently we make pots with more varieties together. Certainly widespread and appreciated on the terraces, is the artificially produced hybrid called “Petunia Surfinia”; drooping downwards and with abundant flowering, this hybrid can exceed two meters in length.

The lantana

The Lantana genus includes about 150 species of shrub and herbaceous plants, all native to South America and Africa. The most common species is the Lantana camara, widely used as an ornamental plant in gardens and parks, although in Latin America and Australia its growth has become so high that it counts it among the hundred most harmful invasive alien species in the world. Lantana bushes are large and voluminous, with green, fluff-covered rhombus leaves supported by fleshy, sturdy stems. The inflorescences are of medium size, round and composed of very small fragrant orange, yellow flowers and in many red, pink and white varieties. Its rusticity is such as to allow cultivation in narrow pots, taking care to carry out constant pruning to avoid excessive growth. To flourish,
