Phytoremediation is widely considered a cost-effective and eco-friendly (green) technique for cleaning Cd-contaminated soils. This process involves cultivating Cd hyperaccumulators that translocate and concentrate the metal from the soil to the roots and aboveground parts. Sedum alfredii Hance ( S. alfredii H) was first discovered in China as a novel hyperaccumulator of Cd, Zinc (Zn), and lead (Pb), characterized by fast growth and large biomass, compared to other Brassicaceae Cd hyperaccumulators. A regulatory network for Cd detoxification and accumulation in S. alfredii H has been identified as a key physiological and molecular mechanism. Recent progress in understanding the physiological and molecular mechanisms of Cd uptake, tolerance, and translocation has already been reviewed. The results show that the Cd uptake occurs through two processes: the soil–to–rhizosphere and rhizosphere–to–root. In the two processes, root exudates in the rhizosphere S. alfredii H, may correlate with heavy metal accumulation, and transporter expression levels in the root plasma membranes may play a key role in Cd hyperaccumulation in S. alfredii H. The plant tolerates Cd in the soil by adapting to Cd-induced oxidative stress. Membrane proteins are considered key transporters for Cd and Zn accumulation in the plasma membrane of S. alfredii H shoots.
