Wakame, *Undaria pinnatifida*, is a sea vegetable, or edible seaweed. It has a subtly sweet flavour and is most often served in soups and salads.
Sea-farmers have grown wakame for hundreds of years in Korea and Japan and it has been nominated as among 100 of the world's worst invasive species according to the Global Invasive Species Database.
