The Common Houseleek (Sempervivum tectorum), also known as “Liveforever” or “Hen and Chicks,” is a captivating succulent that thrives in the rocky mountains of Southern Europe. With its lush green rosettes and remarkable ability to store moisture, this hardy plant has a rich history and offers an easy and rewarding gardening experience. In this article, we will explore the characteristics, cultivation tips, habitat, and popular cultivars of this enduring species.
The Common Houseleek boasts rosettes with a diameter of 3-4 inches, showcasing green leaves with dark tips. These fleshy, thick leaves have a unique capability to store moisture, making the plant well-adapted to survive in arid mountainous environments. Additionally, some varieties of the species may exhibit fine white hairs on their leaves, adding a touch of elegance to their appearance.
The plant reproduces through vegetative propagation, primarily using stem cuttings where young rosettes form at the tips. Alternatively, the Common Houseleek can also propagate via seeds, and it blooms during the summer, with flower stems occasionally reaching up to 10 inches in height.
The Common Houseleek holds a place as one of the oldest cultivated plants. During the Middle Ages, it was frequently planted on rooftops for its believed protective properties. Over time, its ornamental appeal became evident, leading to its use as a charming addition to gardens and landscaping.
