Native plants are the foundation of the healthy ecosystems that support native wildlife and a thriving economy, as well as having their own intrinsic value.
Maryland law requires that each entity that receives State funding and each State agency prioritize, whenever possible, the use of plants native to the State for every planting project.
Maryland Plant Atlas (MPA) provides access to a checklist of vascular plants of Maryland that is updated as new records become available. The MPA is a partnership between the Maryland Department of Natural Resources, the University of Maryland’s Norton-Brown Herbarium, and the Maryland Biodiversity Project. Each plant species in the flora has a species page containing information about whether the species is native or non-native (including invasive species), distribution, sources of records, and photographic images. The Maryland Plant Atlas is synced with the Checklist of Maryland Plants by Wesley Knapp and Robert Naczi (Smithsonian Press, 2021), which is updated as needed on the MPA.
