Native Plants for North Carolina

North Carolina runs about five hundred miles west to east and changes completely along the way. The southern Appalachians in the west include the highest ground in the eastern states and a cove-forest flora of exceptional richness. The Piedmont through the center is rolling red clay. The coastal plain flattens eastward into pine savanna, blackwater swamp, and finally the barrier islands.

Hardiness runs from the mountains, cold enough for northern species, to the Outer Banks, mild enough for near-subtropical ones. Treating this as one plant list would be a mistake in either direction.

The Sandhills and the longleaf country

Between the Piedmont and the coastal plain lie the Sandhills, ancient beach deposits now standing inland as deep, droughty sand. That ground and the coastal plain beyond it were longleaf pine savanna, an open, fire-maintained forest whose ground layer is one of the most species-rich plant communities in North America. Some sites carry dozens of species in a single square meter.

Very little of that habitat survives, and the plants of it, wiregrass, blazing stars, coreopsis, and a long list of others, are excellent garden material for a sunny, sandy, well-drained site.

The Carolina bays scattered across the coastal plain are shallow oval depressions holding seasonal wetlands, with their own specialized flora including carnivorous plants.

Clay, sand, and summer humidity

Piedmont clay holds water and nutrients and suffocates roots in low spots. Plant where water moves rather than pools, and skip the amended planting hole.

Sandhills and coastal sand are the reverse: fast-draining, lean, and best planted with species adapted to exactly that. Do not enrich them.

Humidity is high through summer across the eastern two-thirds of the state, and fungal problems cause more losses than drought. Give plants room for air movement and water at the roots.

Hurricanes and coastal storms are a design factor near the coast. Flexible native shrubs and deep-rooted grasses recover from wind and salt-laden rain far better than brittle ornamentals.

Confirming what is native to your county

The North Carolina Botanical Garden in Chapel Hill is one of the leading native plant institutions in the Southeast and publishes extensive guidance. The North Carolina Native Plant Society runs chapters statewide, and the state's Natural Heritage Program documents natural communities in unusual detail.
