Native Plants for Full Sun in New Hampshire
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 New Hampshire and the wider flora of the Northeast and hardy through zones 3–6 — proven performers for New Hampshire's cool, humid continental climate across White Mountains & northern hardwoods, not a generic list. Local standouts include Golden Alexanders and Great Blue Lobelia. 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.
