This plant has a fibrous root, with several tufts of oblong, acute, extremely succulent leaves. The stem from the centre of these tufts is about a foot high, erect, round, and downy; flowers large, pale rose-colored, and scentless. Offsets spreading.

Sempervivum arachnoideum.Typically, each plant grows for several years before flowering. Their hermaphrodite flowers have first a male stage. Then the stamens curve themselves and spread away from the carpels at the center of the flower, so Self-pollination is rather difficult. The colour of the flowers is reddish, yellowish, pinkish, or – seldom – whitish. In Sempervivum, the flowers are actinomorphic (like a star) and have more than six petals, while in Jovibarba, the flowers are campanulate (bell-shaped) and are pale green-yellow with six petals. After flowering, the plant dies, usually leaving many offsets it has produced during its life.

Cultivation:
Although their subtropical cousins are very frost-sensitive, Sempervivums are among the most frost-resistant succulents, making them popular garden plants. They require only moderate water and some protection from extreme exposure to the sun.

Sempervivums grow very well in dry conditions. Despite this if Sempervivums are grown in normal flower beds among other cultivated plants there can be a problem. If the flower beds are not particularly dry other plants may grow more strongly than the Sempervivums and overshadow them. Other plants may need to be removed, cut back or tied out of the way.

“Semp-lovers” are numerous and often have many different cultivars in their collections. Sempervivums are very variable plants and hence hundreds, maybe thousands of cultivars were created, but a lot of them are not much different from each other. The main interest of these cultivars are not their flowers, but form and colour of the rosette-leaves. The most colourful time is generally from March till June.
