Iowa is home to a diversity of native grass, forb and sedge species. Some have become very rare due to habitat loss but many can still be seen in remnants along roadsides throughout Benton County.

There are many great resources available on prairie plant information and identification. The Benton County IRM program has summarized information from many of these sources and created native plant profiles for species that exist in our roadsides. These can be viewed below.
