Native Plants

Roadside Vegetation – What was once the FHWA Wildflower Program has evolved into a holistic roadside program. Roadside rights-of-way account for more than 10 million acres of land in the United States. This land requires care that assures water quality, improves erosion control, increases wildlife habitat, reduces mowing and spraying, enhances natural beauty, and protects natural heritage. The FHWA Roadside Vegetation Program serves as a technical resource for this care of the land.

  • "Roadside Use of Native Plants" – This glove-compartment size handbook is a reference for those who restore, design, or manage native plants. Its State by State organization of information is a beginning point in decision-making. To make site by site decisions within a State, local expertise will be necessary. This information is aimed at preserving the native remnants that still exist and restoring natural heritage where necessary. Hardcopy versions of the handbook are available by calling (800) 828-1302.
  • Wildflowers – Overview of the use of wildflowers as roadside vegetation.
  • "Greener Roadsides" – Archived issues of FHWA's quarterly newsletter about vegetation management issues.
  • Vegetation Management: An Ecoregional Approach – This publication marks the third and final installment of an FHWA guidebook series on managing roadside ecology. It was designed as a quick-start guide for maintenance staff from State DOTs, as well as landscape, environmental services, and erosion control personnel.

For questions regarding roadside vegetation issues in a particular State, please refer to the list of  Roadside Vegetation Contacts.
