I live in zone 7b. A couple years ago I planted Crassula perforata 'Variegata'
and it seemed to do well for a little while, even through winter (which was mild). In very early spring it died. I had given some to a friend and he said his did not make it through winter. I can't seem to find hardiness zones for this.
When I find more of it I plan to treat it as a houseplant and will let it play outdoors during the summer, but I would love to get it to grow in a future succulent bed.
Thanks!
