Sempervivum 'Onyx' (Onyx Hens and Chicks) is a striking succulent known for its bold, dark purple to black foliage, which intensifies in colour during cooler months. The rosettes of thick, fleshy leaves form a dense, compact mound that creates a dramatic contrast in rock gardens, containers, or as a ground cover. In the summer, it produces small star-shaped pink to red flowers on tall stems, adding a splash of colour to its dark foliage.
Sempervivum 'Onyx' (Onyx Hens and Chicks) is highly adaptable, thriving in full sun and well-drained soil, making it a perfect choice for dry, low-maintenance gardens. As a hardy succulent, it is drought-tolerant and can withstand poor soil conditions. Its unique colouring and easy-care nature make it a standout in any garden, and its ability to spread quickly allows it to cover large areas efficiently.
