Native Plants for Full Sun in Pennsylvania

Sun-loving native wildflowers, grasses, and shrubs for the hot, bright, open parts of the yard that bake all afternoon. Every species here is genuinely native to Pennsylvania and the wider flora of the Mid-Atlantic and hardy through zones 5–7 — proven performers for Pennsylvania's humid continental climate across Appalachian ridge-and-valley & Piedmont, not a generic list. Local standouts include Wild Bergamot and Serviceberry. A spot with six or more hours of direct sun is prime real estate for the prairie and meadow natives that evolved in the open — most want exactly that much light to bloom hard and stand up straight. Give them lean, well-drained soil rather than rich and pampered, skip the fertilizer, and they will reward the tough love with more flowers and sturdier stems.
