Deep-rooted native plants that shrug off heat and dry spells and rarely need watering once they are established. Every species here is genuinely native to Maine and the wider flora of the Northeast and hardy through zones 3–6 — proven performers for Maine's cool, short summers climate across Acadian forest & coastal lowlands, not a generic list. Local standouts include Lanceleaf Coreopsis and Showy Goldenrod. Drought-tough natives earn their reputation with deep roots, so the secret is patience: water them through the first season while those roots reach down, then taper off and let them fend for themselves. Plant in fall or early spring, give them sharp drainage and full sun, and resist the urge to coddle — overwatering kills more of these than any heat wave.
