Native Plants for the Southeast: Warm-Humid Garden Natives

Native plants for the warm-humid Southeast in zones 7–9 — from longleaf pine understory species to coastal plain wildflowers, with sourcing from Clemson, NC State, and UF IFAS.

True natives vs. cultivars in the Southeast

The cultivar controversy applies in the Southeast as elsewhere. Per Clemson Extension HGIC, the definition of a true native plant for the Southeast is "a plant that occurs naturally in a particular region and has evolved over thousands of years in relationship with local soils, climate, and wildlife." Plants from the same species but from northern seed sources may be adapted to different day-length triggers and cold requirements, meaning they may behave differently — or fail — in the Southeast's long growing season.

What NOT to call native in the Southeast: Loropetalum chinense (Chinese fringe flower, wildly popular in the Southeast but native to Asia), Ligustrum sinense (Chinese privet, which has naturalized invasively across the region), and Nandina domestica (heavenly bamboo, native to Asia and invasive in some states). Per NC State Extension, many plants commonly sold as "Southern garden staples" are Asian introductions without the ecological relationships that native species provide.
