Sempervivum Arctic White is a frost-hardy succulent from the Crassulaceae family, native to the mountainous regions of Europe and western Asia where it grows in rocky alpine terrain. It has been cultivated for centuries and remains one of the most popular hens and chicks varieties for both indoor and outdoor growing.
The plant forms tight, symmetrical rosettes covered in fine white webbing that stretches across the leaf tips like delicate threads, creating the signature cobweb succulent look. Fleshy leaves are pale green to silvery-white, and it spreads naturally into dense, clumping mats as the mother rosette produces offsets around its base. Individual rosettes typically reach 2 to 4 inches in diameter and cluster together over time.
When conditions align, flowering rosettes send up a central stalk and bloom, after which that rosette completes its life cycle while the surrounding chicks continue to grow. The plant may require a drop in nighttime temperatures to trigger blooming, a natural cue that mirrors its alpine origins.
It handles balcony wind and rain with ease, tolerates dry heated air indoors, and can move outside for summer or stay outdoors into autumn without trouble. You can leave it up to ten days without water. It is non-toxic and safe to keep in homes with cats and dogs.
