The Iris


This genus of plants is widespread throughout the northern hemisphere, from Europe to Asia, from North Africa to North America, and many are the species that it contains, more than two hundred. There are rhizomatous varieties and bulbous varieties; many taxonomists divide the genus into some subgenres, depending on the presence of tubers or rhizomes, and depending on the shape of the flower. The flower of this plant is well known and known by all garden lovers; all the specimens of this genus produce erect stems on which one or more large flowers bloom, with 3 sepals which tend downwards and three petals facing upwards; some species have a kind of colored down on the tepals, and for this reason they are called barbata; 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 resting on the base of the tepalo. In any case, the flower is easily recognizable, presents spots and streaks in a contrasting color, recalling the colors of pollinating insects. The various species and varieties produce their flowers from the end of winter, like iris reticulata, throughout spring until late summer.

Some speciesGermanic Iris



This species, and its hybrids, presents a squat creeping rhizome, and is widespread in cultivation in European gardens, and also in the wild in European forests; over time, the rhizomes tend to produce large colonies of deciduous leaves; in spring it produces long leaves with a sword, gray-green, sometimes almost blue. From the middle of spring each rhizome produces one or more erect stems, up to 80-100 cm tall, fleshy, cylindrical, which bear long almond-shaped buds. From these buds will bloom large characteristic flowers, with the three tepals widened, completely facing downwards and open, crossed in the center by a downy relief, and the three petals turned upwards. There are many hybrids, in the most varied colors, from pink to purple, from yellow to brown, from violet to green; all characterized by streaks and spots in contrasting colors.
These are easily cultivated plants, 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 place that receives at least a few hours of sunshine 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 scrub widens too much we remember the autumn to unearth the outer rhizomes and place them in another place.

Iris japonica



Vigorous plant, which produces large patches of light green, brilliant foliage; in late spring and in summer it produces large flowers of yellow, white, lilac, with very broad tepals, definitely very decorative, completely without beard. The plant is quite simple to cultivate, it needs to be placed in a partially shaded place, in rich soil. At the beginning of spring it is good to keep the soil moist and fresh, and to provide regular fertilizations until the end of summer.

Iris sibirica



Less intrusive and vigorous than the Germanic variety, even the Siberian irises are very resistant to cold; they prefer a sunny or semi-shaded position, with a fairly cool but not excessively wet soil. They bloom in early summer, and the foliage is bright green.

Iris - Iris: Iris reticulata



Among the first irises to bloom, just at the end of winter, in general 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.
