Ancient legends claim that in Europe the youth was dedicated to the Scandinavian god of thunder and lightning Thor. Therefore, in the Middle Ages, by order of Charlemagne, pretty rosettes were planted on the roofs of houses. At that time, the townspeople seriously believed that such a security measure could ward off a lightning strike from their homes during a thunderstorm.

Description rejuvenated

Rejuvenated, Latin - Sempervivum, folk - stone rose, hare cabbage.

The name comes from the Latin words 'semper' - always and 'vivus' - alive, for the ability of leaf rosettes to remain viable in extreme conditions of existence. In Russia, the plant is also called "stone rose", "hare cabbage", "young". At the moment of flowering, the young resemble a brood hen surrounded by numerous chickens. Hence its popular English name 'Hens and Chickens' - 'hen and chickens'.

The genus has about 30-50 species in Central, Southern and Eastern Europe, the Caucasus, Asia Minor and South-West, mainly in mountainous regions. In Russia, they reach east to the Volga. They grow on rocky, gravelly places, in pine forests on the sand. I rejuvenated the same lifestyle as that of the miners. It hybridizes very easily both in nature and in culture. There are many varieties.

Fleshy, pubescent with glandular hairs, less often - almost naked perennials, forming very dense, many-leaved rosettes of leaves 1-15 cm in diameter and numerous stolons bearing small rosettes of leaves. Flowering stems are usually pubescent with small glandular hairs, erect and unbranched. Monocarpics, i.e. bloom once and die off. Leaves are succulent, alternate, entire, usually ovoid or oblong, sharp or pointed, ciliate along the edge.

The flowers are regular, 8-20-dimensional, bisexual, with a double perianth, almost sessile, collected in corymbose-paniculate inflorescences, separate branches of which are monochasia (i.e. inflorescences in which lateral axes develop under the apical flowers of the main axis, then outgrow in the main and also bearing flowers). Sepals are fleshy, fused at the base, whole-edged, usually covered with short simple or glandular hairs, rarely glabrous.

The petals are lanceolate, always longer than the sepals, usually stellate, white, yellow, yellow-green, red, pink or purple at the edges and outside. There are twice as many stamens as petals, from 16 to 40; those opposite to the petals grow at the base to them, and the next to the petals are free; filaments are usually flattened, pubescent or, less often, bare; anthers oblong, ovate.

The nectar glands are subpastical, small, lamellar, whole at the apex. Gynoecium (ie, a set of flower carpels forming one or more pistils - the female organs of the flower) free of 8-20 unequal, oblong-ovate, usually glandular, sessile carpels; stylodia slightly shorter than ovary, straight, glabrous; stigmas are small, capitate. Fruit of 8-20 oblong ovate or almost lanceolate, pubescent with glandular hairs, polyspermous leaflets.

Some beliefs are associated with the young man. Thus, plants taken internally with wine served as an antidote. A specially prepared tincture made a person's sight and hearing sharper. During the reign of Prince Vladimir, the Red Sun, Russian beauties rubbed their cheeks with rejuvenator to make the blush brighter. The French poet and pharmacist Odo from Maine, who lived during the Crusades, wrote that those who carry a rosette with them would avoid being bitten by a scorpion. In his famous poem "On the Properties of Herbs" thirty-six lines are devoted to the "stone rose" - six lines more than a real rose.

With the constant perfection of their rosettes, the young are infinitely varied in the shape and color of the leaves. The first experiences of using rejuvenated in landscape design date back to the Middle Ages. The inhabitants of medieval Europe entirely planted flat roofs of their houses with them. The memory of this was preserved in the name of one of the species - roofing rejuvenated (Sempervivum tectorum). This plant was also used as a living tile in England.

Decorativeness rejuvenated

Interest in the decorative properties of the young aroused in the 18th century. At the same time, the main methods of planting these plants developed - curbs and carpets from rejuvenated trees appeared in French gardens. They were traditionally used as ornamental plants in parterres, composing lines and shapes. Free, asymmetrical landing appeared later, at the end of the 19th century. At the same time, the first European rock gardens arose, and the young took their permanent place there, traditionally adjacent to low ground cover sedum and saxifrage.

In the second half of the twentieth century, the young became the object of close attention of flower growers, and their purposeful selection began. The Dutch and the Americans, the Germans and the British have been ill with this hobby at different times. Breeding advances in recent decades have followed a new fashion for colored plant forms. Already now in Europe there are many spectacular dark-colored cultivars - from dark carmine to almost black, or rather, deep purple, because there are no black plants in nature. But in our country, specimens of deep saturated color are not yet common.

In general, the number of varieties rejuvenated today is quite large. The number of those registered has already exceeded four thousand. This figure is far superior to the original sixty species. So we can assume that man's attempt to correct nature in this case was a success. It remains to be hoped that these hordes of cultivars will gradually become available to Russian amateurs.

Numerous varieties of juveniles represent a wide range of different rosette colors. There are green, silvery, yellowish, pink, burgundy, and some varieties change the color of the leaves depending on the season. This allows them to be widely used in the creation of colorful "carpets". Different species, when grown together, can be pollinated, and many hybrids have been obtained in culture. Even from natural habitats, interspecific hybrids have been described.

Features of growing rejuvenated

Location rejuvenated

Young people are well adapted to our unstable, sometimes damp, sometimes hot, sometimes cold climate. It is quite stable in culture, does not require other measures against excess moisture, except for good drainage. The most sensitive to dampness is the highly pubescent cobweb rejuvenated. All species and varieties are drought-resistant. Shading, including weeds or leaf decay, is contraindicated for them. Of course, they do not die immediately during overgrowth, but they stretch out, lose their compact shape and bright color.

Soil for young

They thrive on any cultivated soils, avoiding damp ones. But dry, poor, sandy soils are preferred. If the soil contains a lot of nutrients, then the plant, although it forms larger rosettes, but their color will be somewhat paler than usual, and they themselves will be less resistant to overwintering. Soils for all species are desirable neutral or slightly alkaline. For loosening, coarse sand, expanded clay, granite screenings are used.

The landing was young

Plants are planted so that the distance between specimens of large species is 10-15 cm, small ones - 3-5 cm. In a year, the daughter rosettes will completely cover the soil surface.

Care of a young man

Care consists in the timely removal of weeds and faded inflorescences along with a dead rosette of leaves. In moist soil, the lower leaves in the rosette begin to rot. This is the first sign of excess moisture. Once every 3-5 years, if the groups become too crowded and the outlets begin to shrink, the young are seated. Rejuvenated are still not very drought-resistant, especially if they grow on poor soils. They do not die, but they twist the rosettes and lose their decorative effect.

Reproduction rejuvenated

It usually propagates vegetatively, seed reproduction is impractical, since most species form a large number of small daughter rosettes. Their separation and planting are usually carried out in the spring, sometimes in the summer. Very small sockets are grown on the ridges, large ones are immediately planted in a permanent place, keeping a distance of 10 cm.

Seeds are sown in February-March to a depth of no more than 1 mm. Germinated at a temperature of 20 ° C. Seedlings appear in 3-5 days. Seedlings are kept in the light, protecting them from the hot sun. They are planted in a permanent place at the end of June-July.

Use of rejuvenated

Rejuvenated are very effective in group plantings on the southern side of shrubs, in carpet compositions, on rocky areas and slopes.

Partners: Does not get along with lush plants.

Diseases and pests rejuvenated

The main enemy was rejuvenating - birds, namely magpies, jays, jackdaws and crows.

The larvae of the May beetle can also damage the juveniles, they gnaw not only the roots, they would easily cope with this, but manage to eat away the base of the juicy shortened stem. Such rosettes have to be rooted anew, having previously removed that part of the leaves that was left without "support". In those places where the soil is heavily infected with this pest, it is useful to replant the young annually, picking out the larvae from the ground.

Of the diseases, rot of an undetected nature is often troublesome. In rainy, cold weather, individual outlets rot. At first they become as if transparent, and quickly turn brown and "deoxidize". But, as a rule, the process does not spread to neighboring sockets. Those who are sick just need to be removed early, and, it is clear that the process of decay begins from the bottom.
