The Southeast United States — encompassing Virginia, North Carolina, South Carolina, Georgia, Florida, Alabama, Mississippi, Louisiana, Arkansas, and Tennessee — is one of the most botanically diverse regions in North America. Per the Lady Bird Johnson Wildflower Center, the Southeast contains several plant diversity hotspots, including the Appalachian highlands (among the highest vascular plant diversity in temperate North America) and the coastal plain's longleaf pine ecosystem, which once covered 90 million acres and now persists on less than 3% of its historical range.
USDA hardiness zones range from zone 5b in the Blue Ridge Mountains to zone 10b in South Florida. Summers are hot and humid. Soils range from the acidic, well-drained sandy loam of the Piedmont to the heavy clay of the coastal plain and the seasonally flooded soils of river bottoms. Any planting advice that ignores this variation — recommending the same plants for Charlotte and Miami — is oversimplifying.
Trees: the ecological foundation
Longleaf pine (Pinus palustris): Zones 7—10. Per the US Fish & Wildlife Service's longleaf pine conservation program, the longleaf pine ecosystem is the most biodiverse forest type east of the Mississippi and is critically endangered. Longleaf is a foundation species — its fire-adapted open canopy allows a rich groundlayer of native grasses, wildflowers, and orchids. For large properties in the Southeast's coastal plain, longleaf restoration is the highest-value ecological action available.
Live oak (Quercus virginiana): Zones 7—11. The quintessential southern evergreen tree. Like all oaks, it supports high caterpillar diversity. Per Clemson HGIC, live oak is extremely long-lived (centuries), salt-tolerant, and among the most hurricane-resistant trees in the coastal Southeast.
American beech (Fagus grandifolia): Zones 3—9. A large forest tree with smooth gray bark and edible nuts. Supports 100+ caterpillar species. Slow-growing but extraordinarily long-lived. Currently under threat from beech leaf disease in parts of its range.
Flowering dogwood (Cornus florida): Zones 5—9. The spring signature tree of eastern North America — white bracts appear before the leaves in April. Per NC State Extension, it provides berries consumed by 36 species of birds and is the larval host for spring azure and summer azure butterflies.
Eastern red cedar (Juniperus virginiana): Zones 2—9. A native evergreen that provides critical winter cover for birds and larval host for the olive hairstreak butterfly. Per Clemson HGIC, it tolerates a wide range of soils including dry and poorly drained, and is one of the most adaptable native trees in the Southeast.
Shrubs: the understory
Native azaleas (Rhododendron spp.): Several species of deciduous native azalea are endemic to the Southeast, including piedmont azalea (R. canescens), flame azalea (R. calendulaceum), and coastal azalea (R. atlanticum). Per Clemson HGIC's native azalea guide, these species are more heat and drought tolerant than their Asian relatives and are larval hosts for several sphinx moth species. Zones 4—9 depending on species.
Oakleaf hydrangea (Hydrangea quercifolia): Zones 5—9. A native shrub native to the Southeast's moist slopes and stream banks. White flowers June—July, exceptional fall color, exfoliating bark for winter interest. Per NC State Extension, it tolerates part shade and is one of the most ornamentally appealing native shrubs in cultivation.
American beautyberry (Callicarpa americana): Zones 6—10. Grown for its extraordinary magenta-purple berry clusters in fall, which are heavily consumed by birds — the fruit is produced on arching stems alongside alternate leaves. Per UF IFAS Extension, it is a deer-resistant native shrub adaptable to shade and average soil.
Buttonbush (Cephalanthus occidentalis): Zones 5—9. Discussed in the Northeast guide as well — it ranges throughout the Southeast and is particularly valuable in the region's wet bottomlands. July—August white spherical flowers are excellent for butterflies and bees.
Sweetshrub (Calycanthus floridus): Zones 4—9. A Southeast native with burgundy-red flowers in April—June and a distinctive spicy fragrance. Tolerates shade and moist conditions. Per Clemson HGIC, it is a reliable landscape shrub that spreads slowly by suckers.
Perennials: flowers and structure
Cardinal flower (Lobelia cardinalis): Zones 3—9. The most important hummingbird perennial in the Southeast, particularly along stream banks and moist garden edges. July—September bloom. Per NC State Extension, it self-seeds generously in moist conditions.
Blue mistflower (Conoclinium coelestinum): Zones 5—10. An aster-family native with clouds of blue-lavender flowers in August—October. A significant nectar source for migrating monarchs and late-season butterflies. Spreads aggressively by rhizomes in moist soils.
Yellow coneflower (Echinacea paradoxa): Zones 4—9. The only yellow-flowered native coneflower. Native primarily to the Ozarks and portions of the mid-South. Per Missouri Botanical Garden, it requires well-drained alkaline soil — different requirements than the purple coneflower.
Swamp rose mallow (Hibiscus moscheutos): Zones 4—9. A native perennial hibiscus with dinner-plate-sized flowers — up to 12 inches across — in white, pink, and red. Blooms July—September. Per UF IFAS Extension, it thrives in wet and poorly drained soils and is one of the most dramatic flowering perennials for rain gardens and wet margins in the Southeast.
Eastern purple coneflower (Echinacea purpurea): Native through the Southeast as well as the Midwest and mid-Atlantic. High pollinator value as documented throughout Extension literature.
Black-eyed Susan (Rudbeckia hirta and R. fulgida): R. fulgida (orange coneflower) is native to the Southeast specifically and tends to perform better in the region's heat and humidity than the more northern R. hirta. Per NC State Extension, it is one of the most adaptable native perennials for the Piedmont.
Lyreleaf sage (Salvia lyrata): Zones 5—9. A native annual/perennial salvia of the Southeast's forest edges and lawns. Low-growing, with purple flower spikes in spring. Per Clemson HGIC, it naturalizes into lawns and garden edges and is an excellent early spring nectar source.
Grasses and groundcovers
Wiregrass (Aristida stricta): Zones 7—9. The dominant groundcover of the longleaf pine ecosystem, critical for maintaining open forest structure and fire behavior. Per UF IFAS, it is an obligate component of functional longleaf savanna.
Splitbeard bluestem (Andropogon ternarius): Zones 6—9. A native bunchgrass with silvery seed heads in fall. Deer-resistant, drought-tolerant, and among the most visually attractive native grasses in the Southeast.
Coral honeysuckle (Lonicera sempervirens): Zones 4—9. A native vine — not a groundcover technically, but used as one on banks and low fences. Key hummingbird plant in early spring; blooms April—September with peaks in spring and fall.

Regional sourcing
Per NC State Extension, several organizations maintain Southeast-specific native plant resources: the North Carolina Botanical Garden, the Coastal Plains Conservation Initiative, and the Chattahoochee Nature Center maintain regional plant databases and nursery recommendations. The Florida Association of Native Nurseries is the primary resource for Florida-appropriate native plants. Per Clemson HGIC, South Carolina Botanical Garden and the South Carolina Native Plant Society maintain lists of regional nurseries.
Frequently asked
Which native plants work in full shade in the Southeast?
Per NC State Extension, native options for deep shade in the Southeast include native ferns (Christmas fern, wood fern, cinnamon fern), wild ginger, Solomon's seal (Polygonatum biflorum), mayapple, spiderwort (Tradescantia spp.), and native ajuga. Oakleaf hydrangea and spicebush tolerate part shade. True deep shade is limiting for flowering plants in the Southeast as in other regions, but the native fern community of the southeastern forest understory is rich.
Are there native plants for the Florida landscape?
Florida is ecologically distinct from the rest of the Southeast. Per UF IFAS Extension's Florida-friendly landscaping program, native plants adapted to Florida's climate include coontie palm (Zamia integrifolia, the only host plant for atala butterfly), firebush (Hamelia patens), native salvia species, and the range of coastal and wetland species documented in the Florida Native Plant Society resources. Zone 10—11 landscapes in South Florida function more like subtropical and tropical ecosystems than temperate ones.
Does longleaf pine restoration require fire management?
Yes, per the US Fish & Wildlife Service's longleaf pine conservation page. Longleaf pine savanna is a fire-adapted ecosystem maintained by periodic low-intensity fire every 1—5 years. Without fire, the understory becomes dense with shrubs and young hardwoods that shade out the wiregrass layer and the diversity it supports. For landowners with acreage, prescribed fire or mechanical brush removal is required to maintain the ecosystem. For small residential properties, longleaf pine can still be planted as a specimen tree, but the full savanna understory ecosystem requires managed disturbance at scale.
What native plants attract butterflies in the Southeast?
Per NC State Extension's butterfly gardening guide, the highest-value butterfly plants in the Southeast include native passionvine (Passiflora incarnata, host for gulf fritillary and zebra longwing), spicebush, pipevine (Aristolochia macrophylla, host for pipevine swallowtail), native milkweeds, and the late-season composite flowers (asters, goldenrod, coneflowers) for adult nectar.
