What to Eat

Edible parts: Seaweed, Frond, Algae

In Scotland, U. lactuca is used in soups and salads. In Hawaiʻi, U. lactuca is also called limu pālahala and eaten in different ways: mixed with other algae, salted and served with raw fish, boiled in water and served as a soup, or served with chili pepper, onions, soy sauce and sugar. Additionally, U. lactuca has traditional uses in Hawaiʻi as fertilizer and as adornment for hula. When U. lactuca is used for hula it is called limu pāpahapaha. As an alternative to vegetable oil crops, U. lactuca can be a source of biofuels, suitable for transesterification in biodiesel production, and does not require arable land and fertilizers. It can grow in saline and waste water and has a higher ability in sequestering atmospheric carbon dioxide than terrestrial energy crops.

Where to Find It

It grows in tropical and temperate places. They are gathered from rocks along the seacoast. It grows in rock pools and muddy beaches and enters estuaries. It grows well in areas with reduced salinity and thrives where there is not pollution.
