Sempervivum calcareum (Calcareous Houseleek)

Sempervivum calcareum, commonly known as Calcareous Houseleek, is a hardy evergreen succulent prized for its perfectly symmetrical rosettes of blue-green leaves tipped with deep burgundy to purple. Its striking geometric form and colourful foliage make it an outstanding choice for rock gardens, alpine plantings, containers, and living succulent displays.

Native to the mountainous regions of Europe, this resilient succulent thrives in harsh conditions, tolerating drought, frost, and poor soils with ease. It produces clusters of offsets that gradually form attractive mats, while mature plants send up star-shaped pink flowers in summer before naturally completing their life cycle. Easy to grow and exceptionally low maintenance, Sempervivum calcareum is ideal for both beginner and experienced gardeners.
