Distribution and habitat

''Carpobrotus'' chiefly inhabits sandy coastal habitats in mild Mediterranean climates, and can be also found inland in sandy to marshy places. In general, they prefer open sandy spaces where their wiry, long roots with shorter side branches form dense underground network, which extends much further than above-ground prostrate branches. Plants thrive well in gardens, but can easily escape to other suitable places. They easily form wide-area ground covers over a sandy soil, which easily suppresses indigenous sand dune vegetation when ''Carpobrotus'' is introduced to a non-native area. ''Carpobrotus'' is native to South Africa, south Australian coast and coastal Chile. As an introduced species, it became widespread on similar habitats in the Northern Hemisphere: Pacific coast of the United States; Mediterranean and Atlantic coasts of Europe; and New Zealand.
