Native Rain Garden Plants in Maryland

Moisture-loving natives for rain gardens, pond edges, downspout basins, and the low spots that stay soggy after a storm. Every species here is genuinely native to Maryland and the wider flora of the Mid-Atlantic and hardy through zones 6–8 — proven performers for Maryland's humid, four-season climate across Piedmont & Chesapeake Coastal Plain, not a generic list. Local standouts include New England Aster and Spotted Joe-Pye Weed. A rain garden catches roof and driveway runoff and lets it soak in instead of rushing to the storm drain, and these natives are built for that boom-and-bust of flood then dry. Put the most water-tolerant species in the wet center and the merely moisture-loving ones up on the sloped edges. Once established they handle both the standing water and the dry weeks between storms.
