Blackroot - an elegant maxi format flyer
Our cynoglossum is almost unknown under its botanical name. One of the most springy, seemingly, and abundantly colored summers among flower growers and summer residents is lovingly called black root. Despite the fact that there are more than 55 species in the genus of cynoglossums, only one species is mainly used as a decorative culture - the pleasant cinoglossum (Cynoglossum amabile). Throughout the world, it is also known as the Chinese forget-me-not, but we have such a name is rare.
One of the main features of cynoglossum is its rather large size. Even the most modest bushes are stretched up to 40 cm in height, and the best varieties even show off with a meter-long jacket. At the black root leaves are lanceolate, narrow, sit opposite, slightly pressed to the shoots. The surface of the leaves is rough. A thick edge covers both leaves and stems, making the basic light color of the greens seem grayish.
Flowers of pleasant black root reach 2 cm in diameter. In shape, they really look like a forget-me-not, with a prominent center-eye of a not too contrasting color and delicate, rounded petals. Flowers bloom not one at a time, but are collected in unusual inflorescences in the form of curls. Their unusualness is not only in form, but also in a constant increase in the number of flowers: in one inflorescence their number reaches 40 pcs.
The flowering of cinoglossum is long. It does not start in June, but only in July, but splendor fully compensates for such a delay. And the fact that the plant does not slow down until September will not even let you feel the difference with other pilots.
Despite the fact that cynoglossums became famous as spectacular summers with rare blue colors, only the pure shades of blue in the gamma of colors of this plant is not limited. The cynoglossum has no less beautiful pink varieties, the color of which cannot be called anything other than lollipop.
In addition to the basic species plant, there are several cultural forms of cynoglossum pleasant:

- intensively amethyst variety ‘Blue Shower’, growing to 60-70 cm, but with rarer flowers.

Conditions Required by Blackroot
Blackroot feels good at any bright location. He is not afraid even of bright sunny places with a southern orientation, but at the same time he perfectly tolerates light shading. In addition, this plant is not afraid of drafts. Therefore, it is easy for cynoglossum to choose a place in the garden.
The plant does not have special requirements for the soil. Any garden soil with a good level of drainage is suitable for black root. The main thing is that the reaction is not acidic, but alkaline. Neutral soil is also suitable, but on it cinoglossum can bloom less magnificent in anticipation of autumn. When planting, to improve the soil, it is enough to add slaked lime.
The optimal distance to neighboring plants is from 20 to 40 cm, depending on the maximum height of a particular cynoglossum variety.
One of the main advantages of cynoglossum, overshadowing even the duration of flowering, is its drought tolerance. This is a crop that requires minimal care, but it will still need watering. A prolonged lack of moisture affects flowering, its abundance and the beauty of individual flowers. For black root, it is enough to carry out several procedures over the summer, compensating for too intense heat and prolonged drought.
Feeding cynoglossum also will not be needed. Especially if the plant was planted in nutritious, high-quality soil. But if you can water a plant with a solution of complete mineral fertilizers 2 times a season, then the flowering of black root will become even more beautiful. Top dressing is carried out with a standard dose of fertilizers at the very beginning of active growth and at the beginning of the flowering period.
Trimming or shaping cynoglossum is not needed. This plant, with the correct selection of growing conditions and at least minimal care, independently forms not only compact, but also lush, very neat bushes.
Fight against black root pests and diseases
Unlike many flyers, black root does not cause trouble with disease prevention. And he does not attract pests, showing enviable stability.
Black root breeding
Tsinoglossum is prone to self-seeding; when it’s nice, and when it’s not very surprising at the pace of its spread. This quality is an indispensable source of the effect of improvisation for compositions in landscape styles. But in ensembles where such distribution is undesirable, cinoglossum should be used with caution. Young shoots can be transplanted using as seedlings.
But the main method of propagation of black root is still sowing seedlings. The seeds of this plant are best sown in large containers or boxes using a loose, fertile substrate. The optimal time for sowing is the third decade of March or the first decade of April. Seeds cannot be deeply buried: after scattering on the soil surface, they are only covered with a thin layer of sifted soil. They can germinate only in the dark, under glass or film, in the temperature range from 18 to 24 degrees Celsius. Weak seedlings need careful, accurate watering, which should be carried out only as the substrate dries.
Seedlings can be brought to light only after the friendly emergence of seedlings. In this case, the glass is removed as the plants grow, and the dive is carried out after the appearance of several pairs of true leaves.
Planting seedlings in open ground can be carried out already in early May: cynoglossum is not afraid of light short-term frosts, there is no need to plant it at the end of the month or June. Before transplanting, seedlings need to be hardened for 1-2 weeks in the garden.
Black root can be sown directly in open soil. Seeds are scattered on 3-5 pieces in one nest, immediately placing them at a distance of 25-30 cm between groups. Shoots appear in 2, sometimes 3 weeks. The advantage of sowing directly into the soil is the plant's high resistance to heat, drought, and night cooling.
