White Flower Farm Sempervivum Supersemps

Yes, Sempervivum 'Ruby' is hardy in zones 4-9. It is a perennial succulent designed to withstand cold temperatures, provided it is planted in well-draining soil to prevent root rot during wet winters.

Yes, full sun is essential. Without at least 6 hours of direct sunlight, the rosettes will lose their intense wine-red pigment, turn green, and likely become leggy as they stretch toward the light.

It means you can largely leave it alone. Once established, it requires very little water and no fertilizer. You only need to ensure it is planted in rocky or sandy soil that drains quickly.

The mother rosette will die after blooming, which is perfectly normal for Sempervivums. However, the plant will have already produced 'offsets' or 'chicks' around the base, which will grow to replace the original rosette and continue the display.

Absolutely. Because they have shallow root systems and prefer dry conditions, they thrive in containers, troughs, and rock gardens. Just ensure your pot has drainage holes and use a potting mix specifically formulated for cacti or succulents.
