Plant Profile: Sempervivum tectorum

Sempervivum tectorum, commonly known as houseleek, is a flowering plant belonging to the Crassulaceae family. This species is indigenous to the mountainous regions of southern Europe and is widely cultivated across the continent, not only for its aesthetic appeal but also due to a Roman belief that it offers protection to buildings from lightning strikes. It thrives in average, well-drained soils that are dry to moderately moist and prefers full sunlight, although it can tolerate some light shade. This plant flourishes in sandy or gravelly substrates and is resilient in poor soil conditions and periods of drought. To ensure optimal growth, it requires excellent soil drainage, so it's important to avoid overwatering. Sempervivum tectorum propagates by producing offsets, which help it form colonies. After flowering, individual rosettes will die, and it is advisable to remove them from the garden at that point. Additionally, this plant exhibits moderate tolerance to salt.

Sempervivum tectorum is particularly well-suited for rock gardens, as well as for planting along borders, in rock crevices, and beside stone walls. It can also serve as ground cover in small areas, edging, or around foundations, and is best displayed in groups or mass plantings for maximum effect.

Propagation method: Offsets.
