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. At the moment of flowering, the young resemble a brood hen surrounded by numerous chickens. Hence its popular English name "Hens and Chickens".
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 completely planted them with the flat roofs of their houses. The memory of this is preserved in the name of one of the species - roofing rejuvenated (Sempervivum tectorum). This plant was also used as a living tile in England.
Location: All species require well-lit locations but can tolerate light shading. In the shade, the plants lose their compactness, their leaves become pale green, elongate.
Soil: thrive on all cultivated soils, avoiding moist soils. But dry, poor, sandy soils are preferred. If the soil contains a lot of nutrients, then although the plant forms larger rosettes, 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.
Planting: plants are planted so that the distance between specimens of large species is 10-15 cm, small ones - 3-5 cm. After a year, the daughter rosettes will completely cover the soil surface.
Care: consists in the timely removal of weeds and faded inflorescences along with a dead rosette of leaves. Rejuvenated only once - after planting. In moist soil, the lower leaves in the rosettes begin to rot. This is the first sign of excess moisture.
Reproduction: usually 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 rosettes are grown on the ridges, large ones are immediately planted in a permanent place, maintaining a distance of 10 cm. Seeds are sown in February-March to a depth of no more than 1 mm. Germinate 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.
Rejuvenated easily tolerates a long journey in postal parcels and does not need special packaging.
Usage: very effective in group plantings on the south side of shrubs, in carpet compositions, on rocky areas and slopes.
Rejuvenated are very good in groups of different varieties and species against the background of boulders.
Partners: does not get along with lush plants! (fit Dianthus, Saxifraga, Sedum).
