Carpobrotus edulis is extensively planted in gardens and along highways and is also used for dune and bluff stabilization. An invasive, introduced species escaped from cultivation, C. edulis hybridizes with other Carpobrotus species. According to W. Wisura and H. F. Glen (1993), pink-flowered plants are seen in the wild only when C. edulis comes in contact with species of Carpobrotus with purple flowers.
