Salicornia is an annual herbaceous species, also called saltwort. This plant will grow up to 20 to 25 cm above ground. It has a thick stem, with branches, but with little leaves. These facts represent an accommodation to the arid environment.

This plant has a high concentration of salts. It is an edible plant and in French restaurants it is served as a delicacy.

During its first vegetation period, the plant has green leaves, but in time they become reddish, due to the accumulated salts. The Salicornia grows in sandy or highly drained soils, next to other species which prefer a soil with a high concentration of salts.
