The Story
Plant Bio
Iva frutescens, commonly known as Maritime Marsh Elder, is a deciduous to semi-evergreen shrub native to the salt marshes of the eastern and southern United States. It is exceptionally tolerant of salt spray, saline soils, and periodic inundation. As a species, its most distinctive trait is its remarkable adaptability to harsh coastal environments where few other woody plants can survive. It plays a critical role in stabilizing shorelines and providing habitat in tidal marsh ecosystems.
