Carpobrotus rossii (formerly Mesembryanthemum rossii) is a succulent coastal groundcover plant of the family Aizoaceae. Native to southern Australia, it is known by various common names, including karkalla, pig face, sea fig[2] and beach bananas.[3]
C. rossii can be confused with rounded noon-flower Disphyma crassifolium subsp. clavellatum, which has also been erroneously called "karkalla" and "beach bananas" in the Australian native food trade.[4]
Description
Karkalla leaves are succulent, 3.5–10 centimetres (1.4–3.9 inches) long and 1 cm (0.4 in) wide, and curved or rarely straight.[5] The flowers bloom from August through October,[6] are light purple, and are 6 cm (2.4 in) wide. The globular purplish red fruit is about 2.5 cm (1 in) long and 1.5 cm (0.6 in) wide.[5]
Carpobrotus rossii is common on southern Australian coastal sand dunes and is not considered to be at risk.[8]
Uses
Aboriginal people eat the fruit traditionally, fresh and dried. The salty leaves have been eaten with meat. The salty edible leaves should not be confused with rounded noon-flower, which also has edible leaves and is marketed as "karkalla".[citation needed]
Extracts of the plant have significant in vitro antioxidant, antiplatelet, and anti-inflammatory activity.[9]
