Sinyuha blue - a modest relative of phlox. It does not possess brightness and spectacularity, but, meanwhile, it blooms very beautifully and looks great on any garden plot. In addition, cyanosis blue has a number of medicinal properties. The article will talk about planting, care and reproduction cyanosis.
a brief description of
Blue cyanus (or polmonium) is a perennial plant with powerful creeping roots, high stem (reaches 120 cm) and large paniculate inflorescences. 
The leaves are collected in a rosette at the base of the flower. The stem is covered with small leaves that grow perpendicular to it.
Did you know? This plant was considered to be the famous “Ladder of Jacob”, which he saw in a dream and along which the angels descended from the sky. Horizontal leaves gave such a similarity, and a beautiful flower was considered a symbol of paradise.Panicles of blueness consist of flowers resembling bells. The most common color is dark blue, less common is blue. Very rare - it is white.
Aster, geranium, carnation travyanka, bells, cornflowers, astilba, iris, medunitsy, primula will become the best neighbors for cyanosis on the flowerbed.The flowers have a delicate and pleasant aroma that attracts bees. Flowering begins in June-July and lasts until August.
Popular varieties
Despite the rather large variety of varieties of cyanosis, it is grown infrequently. The most popular varieties are:
"Variegata"- a beautiful perennial. Shrub resistant, after flowering remains collected. Foliage with yellow and green stripes. Flowers are small, blue, like bells. Feels good and sunny position, and in partial shade. 
Did you know? The scientific name of the cyanosis is the blue "Polémonium" of ancient Greek origin. It means a battle, a battle, a quarrel. A feud arose between the king of Ponte Polemon and Filetier of Cappadocia because of the one who first discovered the healing properties of this plant. This quarrel gave the name to the plant.'Brise d'anngou' ("Breeze d'Anjou") - a wonderful perennial, with motley leaves, green with a cream border. By autumn, the border turns pink. After flowering, it is better to cut off the peduncles so that the bush looks neat.
Choosing a place
Like any plant, cyanosis develops best in the sun. Although in a small shadow she also feels rather well. The soil is best picked fertile, light, with an abundance of humus and neutral acidity. 
The place itself can be in any part of the garden. The plant tolerates frost and strong winds.
Site preparation
Preparation of the site for planting is to prepare drainage, fertilization and watering.
If the soil is heavy, clay, it must be mixed with sand in a ratio of 1: 1. This will make the earth easier. Acidic soils must be neutralized with lime or dolomite flour.
Sowing seeds
Cyanosis very well grows from seeds.
Sowing should be carried out in the fall, immediately after collecting the seeds. So they will harden and undergo a natural stratification. The optimum daily average temperature for the wintering of the winter is + 2-3 ° C. 
Polymonium is sown in grooves with a depth of 1.5-2 cm. With abundant germination, crops can be thinned. In the spring, when the temperature rises to +4 ° C, the seeds will grow.
Flowering begins in the second year after sowing. Also, the seeds can be sown in the spring, but before that you must keep them in the refrigerator.
Care Tips
Polimonium is an unpretentious plant, care for it consists only in careful watering, weeding and disease prevention.
Watering
Sinyuha loves moisture. Without proper moisture, it begins to fade and loses its beauty. Try to choose a place for the plant with closely located groundwater. 
Or provide good watering, especially in the hot period. Try to prevent the soil from drying out near the roots of the plant.
Weed control
Regularly remove weeds that grow near cyanosis. They can not inflict special harm, but they spoil the appearance of the site where cyanosis grows.
We advise you to learn how to get rid of such weeds as: nettle, birch bindweed, euphorbia, dandelions, field sow thistle, dodder, slyt, quinoa, purslane.
Mulching
To preserve moisture and reduce weed growth, use mulch. Compost, sawdust, peppered humus, peat are well suited as mulch. This will reduce loosening. After all, when loosening, the risk of damaging the creeping roots of polymonium is very high.
Top dressing
Cyanosis very well responds to fertilizers. The first feeding should be carried out in early spring. It is best to use a mineral complex for this (superphosphate, nitroammofoska). 
Superphosphate should be made again before flowering. Top dressing of flowers in the summer will prolong flowering until late autumn. Feed better mineral fertilizers.
Important! Korovyakom can be watered, but only once a season and respecting the proportions, so as not to destroy the flowers.
Pruning
At the end of flowering cyanosis loses its aesthetic appearance. Therefore, the faded plants should be cut and leave only shoots of a length not exceeding 25 cm. An additional advantage will be the active development of the root system after this operation. 
In winter, all the bushes cut almost completely, leave only the stumps about 5 cm long. In this form, the plant will overwinter remarkably.
Diseases and pests
Cyanosis is practically not subject to disease, it does not affect pests. All problems appear due to improper or insufficient watering. Maintain watering mode, do not let the soil dry out, and the plant will not give you any inconvenience.
Other breeding methods
In addition to growing with the help of seeds, cyanosis well reproduces in other ways.
Cuttings
With this method of reproduction, flowering occurs earlier than at sowing. Cuttings harvested in summer. To do this, cut off small shoots up to 15 cm long from the root buds. Remove the leaves from the bottom of the cutting, treat them with solutions to form roots (for example, "Appin"). 
Now they are ready to land in the ground. Cover each planted stalk with a bottle or jar. Periodically open the cuttings for airing and watering. When cuttings take root, cover can be removed. After that, they can be transplanted.
Division of rhizomes
The second breeding method is rhizome division. Apply it to plants older than 5 years. Thus, you will not only get a new plant, but also rejuvenate the old bush. 
The division is carried out in early spring, until the plant has budded. Dig the selected bush and gently clean it off the ground. Use a sharp knife to divide the rhizome into two parts.
Important! Make sure that the roots and growth points are evenly distributed.Fertilize the soil before planting and ensure good drainage. Replant delenki in the prepared pits, water well and carefully grind peat or sawdust.
After planting, water the plant well.
Use in landscape design
Polymonium is often used in landscape design to produce multi-level flower beds with prolonged flowering. Monochromatic bluish flowers are well combined with other plants. 
Very good plant looks and in the decoration of fences and walls of economic buildings, as well as to create mixborders.
Curtains from different grades of polymonium look very picturesque. Here are examples of using blue cyanosis in landscape design and photos.
A beautiful and unpretentious plant, for all its simplicity, will please more than one gardener.
