The Marsh Emergent Site Native Seed Mix consists of site-specific species adaptable to soggy conditions and will withstand some flooding.  These plants require extremely high moisture.  You can test your site by walking across the site wearing tennis shoes; if your feet get wet, this is a good place for the Marsh Emergent Site mix.  Full sunlight is required although some species will tolerate partial shade in this mix such as the Cardinal flower pictured above.
