Help Us Determine the Top Forbs & Grasses for Rain Gardens and Biocells in Iowa

ISWEP is currently updating and revising the 2009 Iowa Rain Garden Design Guide and we’re hoping you can help us gather some new data! We are looking for your top plant species for rain gardens and bioretention cells; species that you either recommend to homeowners or plant routinely in residential, commercial, or municipal projects.

The results will be included in the 2020 Iowa Rain Garden Design Guide and used in new plant layouts and diagrams.
