Sempervivum, commonly known as houseleek, is a genus of succulent plants that thrive in rocky, dry environments. These hardy perennials are characterized by their rosette-shaped leaves, which store water, allowing them to survive in arid conditions. They are often used in gardens and landscaping due to their low maintenance and ability to tolerate poor soil. These plants produce small, star-shaped flowers in summer, attracting pollinators like bees and butterflies. Sempervivum species are also known for their ability to propagate easily, forming new plants, or "chicks," around the base of the parent plant. This makes them popular among gardeners and succulent enthusiasts.
