Cyanosis (Latin Polemonium) - a genus of cold-resistant herbaceous plants of the Sinyukhovye family (Latin Polemoniaceae). As a rule, plants have complex leaves, consisting of numerous small leaves, which gives them a decorative openwork appearance. Inflorescences of small flowers, more often blue-violet colors, are spectacular, but there are white and even yellow ones.

What's in your name

There is no consensus on the meaning of the Latin name of the genus Polemonium.

Some believe that this name is given honor to an ancient Greek philosopher named Polemon, who lived in the 4th-3rd centuries BC. How he stood out among the many namesakes who glorified ancient times is not entirely clear.

Others believe that the Greek word "polemos" is taken as a basis, which translates as "discord", and is again associated with one of the famous Polemons of antiquity, who entered into a dispute with another person who claimed to be the first in the discovery of the healing properties of one of the plant species of this kind.

Varieties

The genus Polemonium has about 50 plant species in its ranks. Let's dwell on some of them:

* Cyanosis blue (Latin Polemonium caeruleum) - rhizome herbaceous perennial plant with a height of 0.35 to 1.4 meters. Hollow single stems of the plant are covered with pinnate leaves, consisting of lanceolate oblong leaves with sharp tips. The ends of the stems are crowned with paniculate inflorescences of wheel-shaped bell-shaped flowers, the corolla of which can be white, blue, purple. The plant gives a short flowering (2-3 weeks) to the world from the second year of life. The almost spherical capsule fruit consists of three nests filled with angular, dark, numerous seeds.

Cyanosis blue, or rather, its short rhizome together with adventitious roots, have versatile healing abilities. They are much more successful than traditional valerian, they help to revive the human nervous system, for which the plant was awarded the popular name "Valerian Greek". It is also an effective expectorant.
