Deep-rooted native plants that shrug off heat and dry spells and rarely need watering once they are established. For Louisiana, the right natives are shaped by Mississippi Delta & Gulf Coast Prairie and a hot, humid subtropical climate. Every species below, from Butterfly Weed and Black-Eyed Susan to the rest of the list, is genuinely native to Louisiana and the wider flora of the Southeast and hardy through zones 8–9. 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.
