About the Plant Atlas

The Indiana Plant Atlas is a botany resource for plant enthusiasts, professionals, students and teachers. The IPA is a joint effort by the Indiana Herbarium Consortium and Butler University to provide users with a comprehensive searchable database of plants that occur growing outside of cultivation in Indiana.

The IPA provides a source of information for each species, including the distribution within the state using historical and recent data. It works on mobile devices and tablets, too!
