Native Plants for the Mid-Atlantic: Coastal Plain and Piedmont

Native plants for the Mid-Atlantic in zones 6–7 — coastal plain, piedmont, and Appalachian species for Maryland, Delaware, Virginia, and the DC corridor, sourced from Penn State, Rutgers, and USDA NRCS.

Coastal plain vs. piedmont vs. mountain ecotypes

Per Penn State Extension, the Mid-Atlantic's "three physiographic regions — coastal plain, piedmont, and Blue Ridge — support different native plant communities with different soil adaptations." Coastal plain soils tend to be sandy and acidic; piedmont soils are often clay-dominated and variable in pH; Blue Ridge soils are rocky, well-drained, and acidic. Using plants native to your specific physiographic zone — rather than "Mid-Atlantic natives" generally — provides the best results.
