Sempervivum Tectorum, also called Roof Houseleek, is a cold hardy succulent in the Crassulaceae family native to the mountainous regions of Europe. It grows naturally in rocky, alpine terrain and has become widely grown in cold hardy succulents for gardens and homes worldwide. This plant needs almost no maintenance and adapts to nearly any outdoor growing condition.
Tight, symmetrical rosettes form the structure of this plant, with fleshy, pointed leaves that shift from green to burgundy-red as temperatures drop or light intensifies. The leaves sit densely packed in geometric patterns, making each rosette visually distinct. Sempervivum Tectorum produces offsets around the base of the mother rosette, creating a spreading clump that widens steadily over time.
When grown outdoors through autumn and winter, it produces a dramatic bloom stalk that rises from the center of a mature rosette, triggering flowering after the plant experiences cool nighttime temperatures. The rosette that flowers completes its life cycle and dies back once blooming finishes, while the surrounding offsets continue growing.
Sempervivum Tectorum handles balcony wind, rain, and dry indoor air without trouble, making it one of the most adaptable succulents for any location. Plant it in a rock garden, on a sunny windowsill, in patio containers, or on a green roof. It is non-toxic to cats and dogs, an important consideration for households with pets.
