This genus of plants is widespread throughout the northern hemisphere, from Europe to Asia, from North Africa to North America, and there are many species that it contains, more than two hundred. There are rhizomatous varieties and bulbous varieties; many taxonomy scholars divide the genus into some subgenera, according to the presence of tubers or rhizomes, and according to the shape of the flower. The flower of this plant is well known and known by all garden enthusiasts; all the specimens of this genus produce erect stems on which one or more large flowers bloom, with 3 sepals that tend downwards and three petals turned upwards; some species have a kind of colored down on the tepals, and are therefore called bearded; some specimens have the ends of the petals and tepals turned downwards and widened to form a labellum; many species have enlarged tepals, and the three petals almost lying on the base of the tepal. In any case, the flower is well recognizable, it has speckles and streaks in a contrasting color, to remind the colors of pollinating insects. The various species and varieties produce their flowers from the end of winter, such as iris reticulata, throughout the spring until late summer.

This species, and its hybrids, has a squat creeping rhizome, and is very widespread in cultivation in European gardens, and also in nature in European woods; with the passage of time the rhizomes tend to produce large colonies of deciduous leaves; in spring it produces long sword leaves, gray-green in color, sometimes almost blue. From mid-spring each rhizome produces one or more erect stems, up to 80-100 cm tall, fleshy, cylindrical, bearing long almond-shaped buds. From these buds large characteristic flowers will blossom, with the three enlarged tepals, completely turned downwards and open, crossed in the center by a fluffy relief, and the three petals turned upwards. There are numerous hybrids, in the most varied colors, from pink to purple, from yellow to brown, from purple to green; all characterized by streaks and speckles in contrasting colors.
These are plants of easy cultivation, which do not fear the cold and do not require great care; it is sufficient to place the rhizome in a good fresh soil, in a place that receives at least a few hours of sun a day, and within 2-3 years we will have a patch of large leaves, followed by beautiful flowers. If we fear that the iris spot is spreading too much, let us remember in autumn to dig up the outermost rhizomes and place them elsewhere.

Vigorous plant, which produces large patches of bright green foliage; in late spring and summer it produces large yellow, white, lilac flowers, with very enlarged tepals, decidedly very decorative, completely devoid of beard. The plant is quite simple to cultivate, it needs to be placed in a semi-shady place, in rich soil. At the beginning of spring it is good to keep the soil moist and cool, and to provide regular fertilizations until the end of summer.
Less intrusive and vigorous than the Germanic variety, the Siberian irises are also very resistant to cold; they prefer a sunny or partially shady position, with a fairly cool but not excessively wet soil. They bloom in early summer, and the foliage is bright green.

Among the first irises to bloom, just at the end of winter, usually the flowers are produced before the foliage, and are purple in color, small in size, carried by stems no higher than 15-25 cm; light green foliage, which persists in the garden throughout the spring.
