Sempervivum 'Emerald': Dense Evergreen Carpet of Green Rosettes

Sempervivum 'Emerald'

Pure, rich green and densely packed, Sempervivum 'Emerald' forms evergreen rosettes that spread slowly to create a very dense, weed-suppressing mat. The rosettes are 2–3 inches across, tightly symmetrical, and a deep, glossy emerald green. Perfect for rock gardens, containers, and desert plantings where a solid green carpet is desired.

Lush Green Uniformity

Unlike many sempervivums that develop red tips, 'Emerald' stays a consistent, rich green year-round. The rosettes are exceptionally tight and uniform, forming a dense colony that suppresses weeds. Offsets are produced freely but stay close, creating a solid mat. In summer, mature rosettes may send up pink flower spikes. The green purity is refreshing in succulent collections dominated by reds and silvers.

Cultural Needs

• Light: Full sun. Best density in full sun.
• Height: 2–4 inches (2 feet or less).
• Spread: 6–12 inches (colonizing).
• Soil: Very well-drained, gritty.
• Water: Low. Drought-tolerant.

Uses & Care

Ideal for green roofs, between pavers, in rock garden carpets, and as a foil for colorful succulents. The dense habit makes it one of the best sempervivums for weed suppression. Very low maintenance. Remove flowered rosettes after bloom. Deer and rabbit resistant.
