The old British folkloric common name for the Sempervivum is rather unusual. It is "Welcome home husband though never so drunk".

Wintersows well. Germination rate very high. Seedlings are slow growing.

"Sempervivum are succulent perennials forming mats composed of tufted leaves in rosettes. In favourable conditions they spread rapidly via offsets, and several species are valued in cultivation as groundcover for dry, sunny spots.

Although their subtropical cousins are very frost-sensitive, sempervivums are among the most frost-resistant succulents, making them popular garden plants. They tend to grow best in dry conditions with well-draining, sandy soil to prevent soggy roots. They require only moderate watering, especially during warmer months, with occasional protection from extreme sun exposure.

Sempervivums also make suitable plants for containers, and do well in breathable terracotta, concrete, and cement pots. They have also been known to grow in rock crevices, metal containers, succulent wreaths, roof shingles, and anywhere else that allows adequate root drainage.

"Semp-lovers" are numerous and often have many different cultivars in their collections. Sempervivums are very variable plants and hence hundreds, maybe thousands of cultivars were created, but a lot of them are not much different from each other. The main interest of these cultivars is not their flowers, but form and color of the rosette-leaves. The most colorful time is generally from March till June."

Is Sardonyx also known as Sempervivum? In other words, what is Sardonyx? Is it just a variety of Sempervivum?
Thank you!
