Sempervivum Supersemp® ‘Onyx’ is a striking variety of hens and chicks, known for its bold, deep burgundy to nearly black rosettes that shimmer like polished stone. This evergreen succulent brings a moody elegance to rock gardens, alpine troughs, and container displays. With its compact form and rich coloration, ‘Onyx’ thrives in full sun, where its tones deepen, especially in cool weather. (Color deepens with age and exposure.) Like all sempervivums, it’s drought-tolerant, hardy to cold zones, and multiplies through charming offsets—creating a low-maintenance, slowly spreading colony of geometric beauty.

Perfect for gardeners who value both structure and style, ‘Onyx’ brings a modern edge to old-world resilience. Its architectural symmetry and brooding tones pair well with pale gravel mulch or silvery companions like Artemisia or lavender. Whether you’re designing a gothic container garden or simply adding contrast to your perennial border, ‘Onyx’ delivers. Add Sempervivum Supersemp® ‘Onyx’ to your collection today and let your garden brood with timeless flair.
