Every year, dozens of distinct wildflower species bloom in Maryland. To maintain the natural beauty of the State and maintain and increase natural habitat, two programs use wildflowers: the Wildflower Program, and the Wild Acres Program.

Since 1986, the Wildflower Program has been overseen by the State Highway Administration of the Department of Transportation. Formed to improve areas surrounding local highways, both in ecology and aesthetics, the Program uses a seed mixture designed to provide blossoms continuously from early March through late November. Since its inception, the Program has planted more than 300 acres of native and naturalized wildflowers along the roadsides and medians of State highways.

The Wild Acres Program offers residents advice and designs to convert backyards into natural habitat, including wildflower meadows. Created to expand wildlife resources and habitat, the Program is run by the Wildlife and Heritage Service of the Department of Natural Resources.
