About
Scaevola taccada, also known as beach cabbage, sea lettuce, or beach naupaka, is a flowering plant in the family Goodeniaceae found in mangrove swamps and rocky or sandy coastal locations in the tropical areas of the Indo-Pacific. It is a common beach shrub throughout the Arabian Sea, the tropical Indian Ocean and the tropical islands of the Pacific Ocean.
There has long been confusion over the correct scientific name for this species. It is also known by the synonym Scaevola sericea.
Where it grows
The species is found in coastal areas and beaches of Okinawa, Taiwan, Southern China, Vietnam, Malaysia, Philippines, Indonesia, East Timor, Northern Australia, Polynesia, Melanesia, Micronesia, East Africa, Madagascar, Mauritius, Seychelles, Oman, Yemen, India, Maldives, Burma, Thailand, Cambodia, Chagos Islands, Comoros, and Réunion.
Uses
In some islands of the Pacific, Scaevola taccada is used to prevent coastal erosion as well as for landscaping. It is also planted on the beach crests to protect other cultivated plants from the salt spray.
