Annual seablite is an excellent plant for salty areas, such as salt marshes. Its family member salicornia is the first land plant to grow in the lowest part of the tidal zone; annual seablite is the next plant just a bit higher up. These two plants have a lot in common. They both catch mud and help build up the marsh. And their leaves absorb a lot of salt and eventually turn red when oversaturated. Should you extract the salt in the leaves of either plant and let it dry, it turns black. This explains annual seablite's latin name Suaeda, which comes from Arabic and means black salt.
