Sempervivum ciliosum borisii is a frost hardy succulent in the Crassulaceae family, native to rocky mountain habitats in the Balkans. It has adapted to harsh outdoor conditions and grows equally well in a garden rockery or a sunny windowsill container.
It forms tight, silvery rosettes densely covered in fine white hairs or cilia that give each rosette a frosted, cobweb-like appearance. It grows in a clustering, clumping habit, steadily spreading to form a wide mat of offsets around the mother plant. Individual rosettes typically reach 2 to 3 inches across. 
It is a monocarpic bloomer, meaning the mother rosette flowers once then makes way for its many offsets to carry on. The plant typically sends up a stalk bearing small star-shaped flowers in summer, after which the surrounding chicks fill in the space. A night temperature drop encourages the bloom cycle, so outdoor or unheated greenhouse growing works especially well for this species. 
Sempervivum Ciliosum Borisii handles balcony wind and rain with ease, tolerates dry heated indoor air, and can be moved outside for summer. It is pet friendly and safe for households with cats or dogs. You can leave it up to ten days without water. It suits rock gardens, alpine troughs, wall crevices, and sunny balcony containers.

Q: How often should I water Sempervivum ciliosum borisii?
A: Water deeply every 10 to 14 days indoors, letting the soil dry completely between waterings. In winter, reduce watering frequency. Soft or translucent leaves indicate overwatering and root moisture buildup.
Q: Is this succulent toxic to pets?
A: No. Sempervivum ciliosum borisii is non-toxic and safe for cats and dogs.
Q: How much light does Sempervivum Ciliosum Borisii need?
A: Place it in a south-facing or west-facing window where it receives several hours of direct sun daily. Insufficient light causes rosettes to stretch and lose their tight, compact form.
Q: How hardy is this plant in winter?
A: Sempervivum Ciliosum Borisii survives temperatures down to -30°F and can stay outdoors year-round in USDA zones 4 to 9. No frost protection is necessary in these zones.
Q: How does Sempervivum Ciliosum Borisii propagate?
A: Separate the offsets or chicks that cluster around the mother rosette and pot them up in gritty, well-draining soil. No special tools or rooting hormones are needed.
Q: Does this plant need rain protection?
A: In containers or rockeries with excellent drainage, Sempervivum Ciliosum Borisii handles normal outdoor rainfall well and suits balcony growing. In prolonged wet winters, rain cover helps prevent root rot, especially in pots without drainage holes.
