They can grow indoors under a Succulent Grow Light or on a south-facing window sill, but they do not show their best colors and can be more vulnerable to rot. All Sempervivum, including Chick Charms, grow best outdoors and can tolerate frosts down to -20F (Zone 5). Cold nights and winters are what bring out their vibrant pigments, and without those they tend to stay greener indoors.
