In the garden
Sempervivum 'Elgar' is a cultivated sempervivum with the typical rosette habit of the genus, producing low, mat-forming clusters of fleshy, pointed leaves that can display green, grey and red tones. As a member of the Crassulaceae it suits dry, sunny positions and accepts a wide soil pH range from acid to alkaline. Place 'Elgar' in full sun on a free-draining loam or sandy substrate; avoid heavy, waterlogged ground. It tolerates both exposed and sheltered sites and will grow on south-, east-, west- or north-facing aspects. Hardiness is H5, meaning it is considered hardy in typical UK gardens without the need for winter protection. Use it where a low, drought-tolerant surface is required: rock gardens, scree beds, wall crevices, gravel troughs and alpine houses are all appropriate. Keep planting positions sharply drained and give only occasional water in the growing season. For a practical finish, plant Sempervivum 'Elgar' flush with the surrounding stone so the rosette surface reads as part of the masonry and it will flower in June to August.
