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 Wyoming and the wider flora of the Mountain West and hardy through zones 3–5 — proven performers for Wyoming's cold, semi-arid, high elevation climate across Rocky Mountain montane & sagebrush steppe, not a generic list. Local standouts include Anise Hyssop and Aromatic Aster. 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.
