Where It Grows
Armenia, Australia, Caucasus, Georgia,
Cultivation
Prefers a well-drained gritty soil in full sun. Succeeds in any sandy soil, doing well in very little soil in rock crevices, walls, paths etc so long as there is sufficient humus. Established plants are drought tolerant. Dislikes winter wet. Hardy to about -15°c. Individual rosettes die after flowering, but produce a number of offsets that continue to grow. This species is closely related to S. tectorum.
Propagation
Seed - surface sow in early spring in a cold frame. Germination typically occurs in 2–6 weeks at 10°C. Prick out seedlings into individual pots when large enough to handle and grow on in the greenhouse through their first winter. Plant out in summer if sufficient growth has been made, or grow on for a further year before planting out. Divide offsets in spring or early summer — larger divisions can go straight into permanent positions, while smaller ones are best potted up and grown on in a lightly shaded cold frame until well established. Plants can also be divided in September, but these divisions should be overwintered in a greenhouse. Propagation by stem cuttings is also possible.
Other Uses
None known.
Notes
There are about 40 Sempervivum species. They grow in the mountains of Europe and Russia.
