Laminaria saccharina is a brown algae which has the characteristic of emerging only at spring tides.

Its name of "saccharina" stems from the sugars which crystallize on the surface of the algae as it dries up.

Laminaria saccharina has nutritional properties close to that of Laminaria digitata but it differs by its thicker structure and by its organoleptic characteristics (slightly sweet taste)

Up to 2 or 3 meters long it grows at the low tides level and is collected from March to June.
