Probably everyone heard about the periwinkle. This unusual culture feels comfortable under any growing conditions. Its representatives are able to cover the surface of the plot with a real carpet, where flowers are interspersed in the middle of a green canvas of unusual beauty.

General description of periwinkle
Periwinkle belongs to the genus Kutrovy. His homeland is Asia and North America, from where he came to almost all corners of the world. This culture is able to grow and maintain a green color both in a temperate climate and under snowdrifts of snow, giving the impression of an evergreen plant. They try to apply such tenacious properties and amazing decorative beauty everywhere when creating garden and park zones. The plant looks great near compositions of stones, in the design of alpine slides and rockeries.
Periwinkle is a perennial grassy ground-cover crop whose branched shoots spread along the ground, forming small sprawling shrubs a little more than 30 cm high or a true green colorful veil.
Oval dark green leaves with a length of 3 to 5 cm and a width of approximately 2.5 cm are formed on petioles placed on thin green or green stems with red tint. Their surface glistens attractively in the sunlight.
Did you know? The periwinkle got its name from the word “barva” because of the colorful flowering. But winka, grave grass, witch violet, zelenka, burial ground, coffin-grass, eye of the devil, the joy of the earth, violet of the sorcerer, gentian - these are not all the names that are sometimes called culture.
Large single flowers of plants bloom in the deciduous sinuses. They consist of a corolla with a long tubular shaft and five petals, which have slight separations at the bent ends. The stamen and ovary column are barely visible in the center. The diameter of the flowers is approximately 3 cm. They have a delicate blue, blue, purple, pink color, slightly different shades at the base and edge of the petals.
The flowering period from April to June depends on the type and variety of plants. Periwinkle fruits are greenish plates resembling a sickle in shape, 7 to 8 cm long, in the middle of which oblong rough brown seeds ripen.
The root system of perennials up to 0.7 m long is shallow, located horizontally on the surface of the earth. Caring for a periwinkle is not particularly difficult. Planting seedlings should be carried out in a not very acidic soil, which consists of a mixture of loam with sand.
It should be borne in mind that representatives of the culture are able to significantly expand in width and strangle neighboring plants. Therefore, the distance between them should be sufficient. Trimming shoots and stopping flowers can also come to the rescue.
This groundcover feels better under sufficient sunlight, but will not translate into partial shade or in a shady place. It should be watered moderately. Fertilizing with mineral fertilizers will be useful. It is recommended to pinch to improve growth. Only after a couple of years, the periwinkle becomes very frost-resistant, before that, young plants need to be additionally covered.To diseases and pests, the culture shows a high level of resistance. Perennial propagation is possible using seeds, layering, cuttings, dividing the bush. But this plant is able to reproduce independently.
