Sea lavender is a perennial with a strong rhizome, evergreen, hard and leathery leaves and tiny violet flowers.
It is a halophyte equipped with salt glands on the surface of its leaves. Through them it discharges the surplus salt, which in dry weather appears in the shape of tiny cubes. Some time ago it used to be picked as a decorative dry flower, which is the reason why its existence has been greatly endangered in the Sečovlje Salina.
