Sempervivum arachnoides

Cobweb Houseleek 

Origin:  Europe/Mediterranean

Light:  Light Shade

Water:  Moderate

__________________________________________________________ 

Sempervivum arachnoides is a delightful departure from the norm.  Sporting spiderweb-like filaments, this species is cold hardy and tolerant of dry conditions.  Many varieties exist under the name 'arachnoides' or 'arachnoideum', etc.  All have webby filaments of varying degrees.

Each rosette is a separate plant and will flower once (monocarpic) and then die - leaving behind many offsets.Individual rosettes can be plucked (some may roll away on their own) to start new plants.  No special treatment is needed - just pot up or stick into a new location.  Roots will form in the coming weeks.

This highly variable species comes in many forms and colors.  Some grow into large mounds or send offsets on their way using stolons where they take root away from the mother plant.
