Introducing the Sempervivum calcareum, a stunning mat-forming succulent perennial variety of the Sempervivum tectorum, that belongs to the Hens and chicks Sempervivum genus.
Native to the mountainous regions of Southern Europe, particularly the Alps and the Pyrenees, the Sempervivum calcareum has several other common names such as lime houseleek, calcareous houseleek, or Sempervivum tectorum var. calcareum. The name "calcareum" refers to its preference for growing in limestone-rich soils.
Sempervivum calcareum forms beautiful densely packed evergreen rosettes of plump juicy leaves that are typically blue-green or pale green in color with flush red tips.
These sharply pointed leaves have a powdery coating called "farina" that provides protection against intense sunlight and helps retain moisture.
The rosettes, which can grow up to 4 inches wide, spread in all directions by horizontal stems, resulting in an attractive carpet-like appearance.
The Sempervivum calcareum flowers bloom during late spring or early summer with tall flower stalks that rise above the rosettes. The flowers can vary in color, ranging from shades of pink, red, or yellow. The blooms attract pollinators like bees and butterflies, adding a touch of vibrancy to the Sempervivum plant.
When it comes to Sempervivum calcareum care, it is a low-maintenance plant that thrives in well-drained soil with medium moisture. They accept poor soil conditions and flourish in sandy or gravelly soils. Sufficient drainage is required. Plant this succulent in full sun exposure for the best health and growth. It thrives in rock gardens, where heat is reflected off the rocks. Water sparingly, allowing the soil to dry out between waterings, as it can cause root rot.
This cold-hardy succulent can thrive in USDA hardiness zones 5a to 8b, surviving temperatures as low as -20°F in winter, and thrives in indoor environments with temperatures between 60-85°F. During the winter months, protect it from excessive moisture to prevent damage. Fertilization is generally not necessary, as these plants are adapted to nutrient-poor conditions.
Sempervivum calcareum can be propagated through offsets, which are small "baby" plants that grow around the base of the mother rosette. These offsets can be gently removed from the mother plant and replanted to establish new offsets or chicks. Additionally, it can be propagated through leaf cuttings or by sowing seeds.
Additionally, the Sempervivum calcareum is generally considered non-toxic to humans and pets. These succulent plants are one of the finest options to gift.
