|
The genus Sempervivum, from the Crassulaceae family, comprises 40 species of succulent plants native to North Africa, the Middle East, and Europe. Some species are: Sempervivum calcareum, Sempervivum tectorum, Sempervivum arachnoideum, Sempervivum montanum, Sempervivum minutum, Sempervivum pittoni. Common names: Houseleek, House Leek. This species is native to the Alps, Europe. They are small succulent plants that form groups of beautiful rosettes that reach 12 cm (4.72") in diameter. The decorative, fleshy leaves are light green with a maroon or purple tip. The flowers appear on long flower stalks and can be pink, white, yellow, or red. They bloom in the second half of summer; the mother rosette dies after flowering but produces lateral suckers. They are used in rockeries, on rocky slopes, in wall crevices and in wide pots for balconies, terraces, patios and windows. The Sempervivum calcareum prefers a semi-shade exposure receiving sun in the early hours of the day. They resist frost well. They grow in any type of well-drained soil, especially rocky or stony soils. The pot transplant is done in spring or autumn. Water moderately, waiting until the substrate has completely dried; reduce watering in winter. They resist drought well. They do not need fertilizer or pruning. They are plants resistant to the usual pests and diseases but sensitive to excess humidity. They are easily propagated by separation of suckers. |
