Carpobrotus

Five of the six assessed members are rated resistant. Among them, hottentot fig has support from a handful of assessments, while Pigface and Karkalla each appear on two listings. Canberra’s live Plant Selector explicitly marks Karkalla as fire retardant, and a review reports that Pigface regularly appears on multiple fire-retardant plant lists.

The strongest explanation belongs specifically to hottentot fig. An arboretum included it among 30 recommended low-growing plants because of its leaf-moisture capacity under normal garden conditions. That finding helps explain this species’ rating, but it should not be stretched into a claim about every Carpobrotus. The genus belongs to the Aizoaceae family and is grown as succulents and shrubs; the common name “pigface” applies to three of its six assessed members.

The overall answer therefore leans clearly toward fire resistance, but species identification still matters. One assessed member received no verdict, which means the available sources did not place it on either side. For a particular plant, use the species-level finding rather than assuming the common name settles the question.
