Native to central and southern Europe, the plant now grows wild in northern Europe, North Africa, and western Asia. It is a succulent perennial, growing to four inches and producing round rosettes of leaves and flowering stems which bear clusters of bell-shaped red flowers. A widely cultivated ornamental garden plant, it spreads easily and prefers sandy, dry soil.
The Frankish King Charlemagne (742-814 CE) told his subjects to plant the herb on their roofs since it reputedly warded off lightning and fire.
The botanical name of Sempervivum means "forever living," referring to its hardiness — but not enough to ward off lightning and fire.
