Iva imbricata is a North American species of flowering plant in the family Asteraceae known by the common names dune marsh-elder and seacoast marsh elder. It is native to Cuba, the Bahamas, and coastal areas of the United States from Texas to Virginia. It is a low shrub, found on sand dunes and the upper beach. It is a highly salt tolerant plant, and is often the perennial plant closest to the ocean.
