Wherever the periwinkle grows, also known as "witchcraft violet"! Plants of this species are found in almost all corners of Europe, in Asia and Africa, and possess an amazing ability to take root, barely coming into contact with wet earth. This feature of the plant explains the diversity of its species and varieties, the most popular of which are small, large, pubescent and grassy periwinkle.
Small periwinkle (Vinca minor)
The small periwinkle is a small evergreen, upright or creeping shrub up to 35 cm high. Its creeping stems reach a length of one and a half meters and form a dense beautiful carpet, laying on the ground and rooting at the place of contact with it. The leaves are glossy, elliptical shape.Blue, blue or pale lilac single flowers are located on upright stems in the axils of the leaves. This periwinkle has a flowering period from mid-spring to early fall. The fruit resembles a long arc curved leaf.
Vegetatively reproduces. It grows mainly in deciduous (oak, hornbeam and mixed) forests, on forest edges, in ravines, steppe slopes, clearings, and also in river valleys where there is a lot of light and heat. In addition to wildlife, this plant is very popular among summer residents and it is well acclimatized in household plots, it is used not only for decorative purposes, but also for medicinal purposes.
Small periwinkle is very widely used in medicine - both traditional and folk.Preparations based on this plant are used as a vasodilator, sedative, antimicrobial, sedative, hemostatic and astringent. The substances contained in the plant are used to treat hypertensive diseases, tachycardia, cerebral vasospasm, various types of neurosis, and other diseases of the nervous system and psyche, including depression and schizophrenia.
Vinca medications are effective for various otolaryngic and eye diseases, especially those caused by infections and circulatory disorders. Breeders have deduced several varieties of Vinca minor, among which the most famous:
- Alboplena, distinguished by white small flowers, double in structure;
- Argenteo-variegata - a plant with very beautiful large leaves of bright green color with beige-white splashes and blue flowers growing in inflorescences;
- Atropurpurea - periwinkle with very bright purple-red flowers;
- Emily - white flowers;
- Bowles' Variety, characterized by a particularly long flowering period and rich color of flowers.
Vinca major
Greater periwinkle is much less known than its "little fellow", although no less sympathetic. It is a larger shrub found in Eurasia and North Africa, growing in the wild and in the domesticated form.
The leaves of the greater periwinkle are longer and wider than those of the small, with a shape similar to a heart. If the small periwinkle is glossy, then the large one is matte. Flowers have a lilac shade and larger.
The periwinkle is large and spreads with thin stems and takes root in the nodes, forming a dense coating (however, this type of periwinkle grows rather slowly).
In general, the plant is quite shade tolerant, but can grow in sunny places. Much more great periwinkle whimsical to the prosperity of moisture and soil fertility.
The most interesting variety of large periwinkle is Vinca major Variegata, in 2002 awarded the Royal Horticultural Society of Great Britain Award of Garden Merit. It is known for the absence of flowers and motley leaves of an egg-shaped form, decorated with white patches and border, and completely white leaves are sometimes found.
This subspecies does not form a carpet and less like a bush.
Vinca pubescens
This type of periwinkle is most often found in humid wooded areas of the Caucasus and, unlike the two previous varieties, it is practically not cultivated by gardeners.As described earlier varieties, the plant is able to spread out a dense carpet in a fairly extensive area. Flowers blue, medium size, rising on a long stalk. Appear in late spring - early summer, the total flowering period - 25-30 days. Periwinkle pubescent poorly tolerates frost and sheds foliage for the winter. Needs shelter from frost.
Periwinkle herbaceous (Vinca herbacea)
Unlike large and small periwinkle, this species is not a shrub, although its stems are also capable of climbing along the ground or rising above it. It has 2 types of leaves: from below - round or ovate, from above - oblong, pointed, covered with edges with a rough fuzz. It blooms in late spring - early summer with small blue-violet flowers, the petals are sharp.
The herbaceous periwinkle is found in Ukraine and in the Caucasus. Like the small periwinkle, this plant contains a large number of alkaloids that help lower blood pressure. Used in medicine, showed a good effect in the treatment of gastric ulcers.
Just as the periwinkle is pubescent, this variety does not tolerate frosts, therefore it often dies in winter.
Vinca Rose (Vinca rosea)
The homeland of periwinkle pink, better known under the name Qarantus, is considered to be the island of Madagascar. It also grows in India, Indochina, the Philippine Islands, Cuba and other exotic corners of the world.
In the Soviet period, began to be cultivated in Georgia, Kazakhstan and Kuban.
This is a very beautiful evergreen shrub with upright stems up to 60 cm in height. Small flowers pink (from pale to bright), less often - white shades are located in the axils of the upper leaves. As a result of selection of several varieties of pink periwinkle, such hybrids were bred:
- Grape Cooler, whose flowers are purple with a pink eye,
- Peppermint Cooler - a red peephole against a white flower,
- First Kiss is a whole series of varieties with more than a dozen different shades.
Periwinkle in the wild is represented by a dozen different varieties; however, the plant has achieved the greatest variety of forms, colors, growing conditions, period and duration of flowering thanks to the many years of breeders.
