Sempervivum 'Sun Queen' is a frost-hardy succulent from the Crassulaceae family, native to the mountainous alpine regions of Europe where it grows in rocky crevices and high-altitude terrain. It forms dense clusters of geometric rosettes and tolerates extreme cold and dry conditions that challenge most other plants.
The leaves are thick and fleshy, with golden-yellow centers ringed by green outer edges that shift to reddish-pink at the tips when exposed to bright sunlight. Each rosette grows 3 to 4 inches across with a perfect geometric shape. Sun Queen produces numerous offsets that cluster tightly around the mother plant, building dense mounds over time.
In summer, tall flower stalks emerge with small star-shaped blooms in shades of pink or yellow. It tolerates fierce balcony wind and heavy rain without damage and is completely safe around cats and dogs.
Sun Queen grows slowly and requires no fertilizer, growing well even in poor soil. It serves as a groundcover or container plant both indoors and outdoors year-round. You can leave it up to ten days without water.
