Crassula radicans

Crassula radicans is a small, creeping, mat-forming Crassula from South Africa, often treated as a form of Crassula pubescens, whose fleshy leaves turn red in strong light. It grows easily in bright light with a gritty mix, and does best with mild nights and less water during the hottest part of summer.
