You won't mistake this plant as you walk on a salt marsh through a group of sea wormwood plants. They emit a strong lavender-like odor, even the dead dried up plants that still stand in the winter. From a distance, the plant is easy to identify by its silver-gray color. You see silver fields of sea wormwood growing between the purple sea lavender. Sea wormwood grows almost exclusively on slightly elevated, sandy borders of flowing gullies in salt marshes. It is the last plant to flower on the salt marsh but its flowers are very small.
