The blue flowers

What are the blue flowers?

Finding your way around the flowers and selecting the ones we like most or are interested in from a botanical point of view can be a difficult task. In gardening, in the field of decorations and outdoor furniture, the blue color is particularly sought after, a symbol of creativity and harmony. There are many species of plants that produce flowers of various blue tones, some particularly intense: some violets are blue or light blue, or the small flowers of veronica, finely crossed by thin white bands on a blue / violet background, as well as many hybrid varieties of iris and cultivated tulips. Often combined with blue there is white, blue, purple, purple and the colors are not always homogeneous. Totally blue flowers are uncommon, but not non-existent; forget-me-not is undoubtedly one of thebest known blue flowers , full of history and legends handed down over the years.

The genus Myosotis

The term forget-me-not indicates some species of flowers belonging to the genus Myostis, family Boraginaceae. Widespread in much of the world, the species that make up this genus are about fifty, well known since ancient times for their therapeutic properties; in fact, it seems that the infusion based on flowers is effective against some diseases that affect the lungs and the gastro-intestinal system. Forget-me-not is an annual herbaceous plant, with lanceolate and toothed leaves on both sides and an intense green color. The flowers are small, composed of five blue petals and grouped in more or less thick inflorescences depending on the species. It grows spontaneously in a large part of the territory, but it is possible to grow it at home or in the garden. The Greek term Myostis means “mouse ears”,

The plumbago

The Plumbago genus is composed of about ten species of shrubby or climbing plants, belonging to the Plumbaginaceae family. The stems can exceed a length of 4-5 meters, especially in climbing species, and are particularly resistant and leathery. The leaves are oval, light green, and often covered with a sparse down. The flowers are small and composed of five blue, white or lilac petals depending on the species, grouped in large rounded inflorescences. The most common ornamental species of plumbago is Plumbago auriculata, appreciated above all for the sky-blue color of its flowers and for its covering capacity on gates and surrounding walls. In temperate zones they resist mild winters well, while in the North they are grown in greenhouses or sheltered areas.

The blue flowers: blue hybrids

Thanks to the importation of plants in past years, we now have a huge variety of artificially produced hybrids, which modify the shape and, above all, color of the original species, becoming almost new species in their own right. This is the case, for example, of the American Ceanothus, evergreen trees with an arboreal habit with white flowers, belonging to the Rhamnaceae family. There are now about fifteen varieties of Ceanothus hybrids with blue flowers on the marketinstead of white; the most common and easily found in nurseries is called “Ceanothus x cascade”, with sky-blue flowers grouped in long panicle inflorescences. Most of the Ceanothus hybrids are rustic plants, which are well suited to any type of soil and adverse temperatures, giving from spring to summer large and thick flowering foliage.
