Sempervivum 'Dark Beauty'

Sempervivum 'Dark Beauty' is a cultivated member of what is commonly known as houseleeks, in the Crassulaceae family. It originates from breeding work using species native to the mountainous regions of southern Europe, where they grow in rocky crevices and shallow, well-drained soils under full sun. This natural heritage provides excellent tolerance to drought, low-nutrient soils, and freezing winter conditions.

The rosettes are compact and symmetrical, with fleshy, pointed leaves that can develop deep burgundy to almost black tones, especially in cooler seasons or under strong light. Seasonal changes influence the foliage colour, adding to its ornamental interest. Offsets are produced readily, forming dense clusters over time. As with all Sempervivum, each rosette is monocarpic, flowering once before dying, with offsets maintaining the plant’s presence.

Flowering generally occurs in summer when mature rosettes produce tall stems topped with clusters of star-shaped blooms. The flowers are usually pink to reddish and are attractive to various insect pollinators. After flowering and seed production, the rosette dies back, leaving surrounding offsets to continue growth.

Care Tips:

• Light: Full sun is ideal for compact growth and the richest foliage colour.
• Water: Water sparingly, allowing the soil to dry completely between applications.
• Media: Gritty, sharply draining mix suited to alpine and succulent plants.
• Fertiliser: Occasional feeding with a diluted, low-nitrogen fertiliser during active growth.
• Temperature: Hardy to frost and prolonged freezing when kept dry.
• Repotting: Rarely needed; divide and replant offsets or refresh the substrate when clumps become crowded.
