• Heat-and-drought compound stress is the dominant climate-adaptation pressure here, not winter cold — multi-week summer drought windows are lengthening on the western edge.
• Loblolly, shortleaf, longleaf, and slash pines all carry forward; bottomland hardwoods (water oak, swamp chestnut oak) face episodic flood-and-drought whiplash on the river systems.
• Garden-relevant: deep-rooted natives (Texas star hibiscus, beautyberry, oakleaf hydrangea) outperform thirstier ornamentals as summer rainfall becomes more episodic.
