Sempervivum 'Silver Angel' is a cold hardy succulent in the Crassulaceae family, native to the mountainous regions of Europe and western Asia. It evolved in rocky, high-altitude terrain where drought and frost are constant, making it one of the toughest frost tolerant succulents for outdoor year-round growing.
Silver Angel forms tight, symmetrical rosettes with fleshy, silvery-toned leaves that have an almost metallic appearance. It clusters readily as offsets (the "chicks") grow around the central rosette (the "hen"), spreading outward over time to create a silvery mat. Individual rosettes reach 2-4 inches across, staying low and compact even as the cluster expands.
Each rosette blooms once in its lifetime, then dies back while surrounding offsets continue the plant's life cycle. Silver Angel needs a drop in nighttime temperatures to trigger flowering, so outdoor growing in a naturally cycling environment encourages blooms season after season.
Rock gardens, container arrangements, green roofs, and border edges are all well-suited to this clustering succulent. You can leave it up to ten days without water. Move it outside in summer or leave it outdoors year-round in cold climates. Silver Angel is pet friendly and safe for households with cats and dogs.

Sempervivum 'Silver Angel' grows well in full sun to partial sun, needing at least 4-6 hours of direct light daily.
Water it deeply but infrequently, allowing soil to dry completely between waterings, roughly every 10-14 days.
Silver Angel does best in fast-draining succulent or cactus mix blended with coarse perlite or grit.
It handles a wide range from summer highs down to frost, tolerating temperatures well below 32°F.

Q: How long can it go without water?
A: Sempervivum 'Silver Angel' survives up to ten days without watering during travel or extended absences.
Q: How does Silver Angel propagate?
A: Detach a healthy offset from the mother rosette, let it dry for a day, then plant it in well-draining soil.
Q: What happens if it gets too much shade?
A: Silver Angel will stretch taller than normal and lose its compact form; at least 4-6 hours of direct light keeps it dense.
Q: How quickly does Silver Angel spread?
A: Offsets multiply gradually over time, creating wider clusters each season without needing any intervention.
Q: Can it grow indoors year-round?
A: Silver Angel prefers outdoor conditions where natural temperature drops trigger flowering and maintain its rosette shape; indoor heating and stable temperatures prevent blooms and loosen the form.
