At first glance, cynoglossum can easily be mistaken for a relative of forget-me-nots. A unique pale blue color, pure amethyst tones of simple small flowers, and indeed, are similar to some of the most classic garden plants. But cinoglossum is a different plant in terms of flowering. It blooms not just for a couple of weeks in spring, but literally the entire warm season. During the long parade, the lush bushes are covered with the lacy foam of flowers, captivating with beautiful details and abundance. Despite their rather large size, cynoglossums give the impression of elegance, they set graceful and touching accents.

Chernokoren - an elegant maxi format summer dress

We have cynoglossum almost unknown under its botanical name. One of the most spring-like, in appearance, and abundantly flowering summer season among flower growers and summer residents is lovingly called the black root. Despite the fact that there are more than 55 species in the genus of cynoglossum, only one species is mainly used as an ornamental culture - cinoglossum pleasant (Cynoglossum amabile). It is also known all over the world as the Chinese forget-me-not, but we rarely find this name.

One of the main features of cynoglossum is its rather large size. Even the most modest bushes stretch up to 40 cm in height, and the best varieties even adorn with a meter-long curtain. Blackroot leaves are lanceolate, narrow, sitting opposite, slightly pressed against the shoots. The surface of the leaves is rough. Dense fringes cover both the leaves and the stems, making the base light color of the greens appear grayish.

The flowers of a pleasant black root reach 2 cm in diameter. In shape, they really look like forget-me-not, with a prominent eye-center of a not too contrasting color and delicate, rounded petals. The flowers do not bloom one by one, but are collected in unusual inflorescences in the form of curls. Their uniqueness is not only in the form, but also in the constant increase in the number of flowers: in one inflorescence, their number reaches 40 pcs.

Cinoglossum bloom is long lasting. It does not start in June, but only in July, but the splendor fully compensates for such a delay. And the fact that the plant does not slow down until September will not even make you feel the difference with other annuals.

Despite the fact that cynoglossums became famous as spectacular annuals with rare blue colors, the range of colors of this plant is not limited only to pure shades of blue. In cynoglossum, pink varieties are no less beautiful, the color of which cannot be called otherwise than candy.

In addition to the basic species plant, there are several cultural forms of cynoglossum pleasant:

  • charming sky blue cynoglossum 'Firmanent' with a more lush squat bush up to 40 cm high;
  • intense amethyst variety 'Blue Shower', growing up to 60-70 cm, but with more rare flowers.

Any black root is a wonderful honey plant. And even if its aroma does not fill the garden with a cloud of fragrant overtones, it will attract many insects to it. In addition, cinoglossum is also a valuable medicinal plant that is actively used in folk medicine. But self-collection of raw materials is risky: along with medicinal species, there are poisonous forms of cynoglossum, which can cause severe intoxication. Cynoglossum pleasant has unique insecticidal properties: it repels rodents and can be used at the end of the season as protection of young trees and shrubs from their winter raids.

And the hotter the weather, the closer the autumn - the more graceful and as if transferred from another season at the wave of a magic wand the blackroot seems.

Conditions Needed by the Blackroot

Blackroot feels good in any light location. He is not afraid of even bright sunny places with a southern orientation, but at the same time it perfectly tolerates light shading. In addition, this plant is not afraid of drafts. Therefore, it is easy to find a place in the garden for cynoglossum.

The plant has no special requirements for the soil. Any garden soil with a good level of drainage will work for blackroot. The main thing is that the reaction is not acidic, but alkaline. Neutral soil will work as well, but cynoglossum may bloom less lush on it in the run-up to fall. When planting, to improve the soil, it is enough to add slaked lime.

Blackroot planting

The optimal distance to neighboring plants is from 20 to 40 cm, depending on the maximum height of a particular cynoglossum variety.

Cinoglossum care

One of the main advantages of cynoglossum, overshadowing even the flowering duration, is its drought resistance. This is a crop that requires minimal maintenance, but it will still need watering. Prolonged lack of moisture affects flowering, its abundance and the beauty of individual flowers. For a blackroot, it is enough to carry out several procedures over the summer, compensating for the too strong heat and prolonged drought.

Top dressing of cynoglossum is also not needed. Especially if the plant was planted in nutritious, high-quality soil. But if you can water the plant with a solution of complete mineral fertilizers 2 times a season, then the flowering of the 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 start of the flowering period.

No trimming or shaping of cynoglossum is required. With the correct selection of growing conditions and at least minimal care, this plant independently forms not only compact, but also lush, very neat bushes.

Blackroot pest and disease control

Unlike many annuals, black root will not cause trouble with disease prevention. And he does not attract pests, showing an enviable resistance.

Blackroot propagation

Cynoglossum is prone to self-seeding; when it is pleasant, and when it is not very surprising with the pace of its distribution. This quality is an irreplaceable source of improvisation effect for compositions in landscape styles. But in ensembles where such a spread is undesirable, cinoglossum should be used with caution. Young shoots can be transplanted using as seedlings.

But the main method of breeding blackroot is still sowing for 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. The seeds should not be buried deeply: after spilling over the soil surface, they are only covered with a thin layer of sifted soil. They can only germinate in the dark, under glass or film, in a temperature range of 18 to 24 degrees Celsius. Fragile seedlings need careful, accurate watering, which should be done only as the substrate dries up.

Seedlings can be brought into the world only after the 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 at the beginning of 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, the seedlings need to be hardened for 1-2 weeks in the garden.

Blackroot can be sown directly into open soil. Seeds are scattered in 3-5 pieces in one nest, immediately placing them at a distance of 25-30 cm between the groups. Seedlings will appear in 2, sometimes 3 weeks. The advantage of sowing directly into the soil is that the plant is highly resistant to heat, drought, and nighttime cold snaps.
