Cutleaf coneflower
Rudbeckia laciniata
A tall native eastern North American perennial with deeply-lobed foliage and bright-yellow drooping ray flowers around a green central cone in midsummer through fall. Spreads vigorously by rhizomes; site where colony formation is welcome. Among the most cold-tolerant native rudbeckias.

Baptisia australis
Blue false indigo
A long-lived native perennial of central and eastern US woodland borders and prairie meadows with deep blue pea-shaped flowers in late spring, blue-green leguminous foliage, attractive black seed pods for winter interest, and a nitrogen-fixing root system (Fabaceae). Larval host for 6 documented butterfly species per NC State (orange sulphur, clouded sulphur, frosted elfin, eastern tailed-blue, hoary edge, wild indigo duskywing) — among the highest Lep-host-count perennials in the eastern flora.
Lobelia cardinalis
Cardinal flower
A short-lived native perennial of wet woodland edges, stream banks, and ditches across the Americas, named for the brilliant scarlet-red flowers that rise on erect, unbranched terminal spikes from mid-to-late summer. Each tubular, two-lipped bloom is shaped for the hummingbird tongue — the plant depends on ruby-throated hummingbirds for pollination because most insects cannot work the long flower tube. It demands constant moisture and tolerates brief flooding, but its foliage carries alkaloids that are very toxic to humans if eaten.
Penstemon digitalis
Foxglove beardtongue
A native upright perennial of central + eastern North American prairies, woodland margins, and open woods producing tall vertical spires of white tubular flowers in late spring. The species name "digitalis" honors a flower-shape resemblance to true foxglove (Digitalis purpurea) — but Penstemon digitalis is NOT toxic in the same way (NC State explicit: "lacks the toxicity associated with foxglove"). Specialist Penstemon mason bee (Osmia distincta) relationship per NC State. The popular 'Husker Red' cultivar adds burgundy foliage for foliage-color design.
Hibiscus moscheutos
Hardy hibiscus
A bold, moisture-loving native perennial of eastern North America that dies back to a woody base each winter and returns to throw up stout 2-6 ft stems topped with enormous 4-8 inch saucer-shaped flowers — white, pink, red, or burgundy, each with a contrasting central eye — from June into September. NC State Extension describes a herbaceous perennial hardy across USDA zones 4a-9b that thrives in wet to constantly moist soils, tolerates heat, humidity, and even brief flooding, and draws hummingbirds, butterflies, and other pollinators. The tropical-looking dinner-plate blooms make it a dramatic focal point for rain gardens, pond edges, and the back of a sunny border.
Asclepias incarnata
Swamp milkweed
A more refined garden-behaved cousin of common milkweed (Asclepias syriaca) — same monarch host status and ecological value, but clumping rather than aggressively spreading, well-suited to rain gardens and consistently moist sites. Pink fragrant flower clusters from mid-summer through early fall; 2005 NC Wildflower of the Year. NC State tags Poisonous (cardiac glycosides) — the same toxicity that makes monarch caterpillars unpalatable to vertebrate predators.
Sambucus canadensis
American elderberry
A fast, suckering native shrub of streambanks and moist thickets across eastern North America, grown for huge flat-topped cymes of tiny lemon-scented white flowers in early summer and the clusters of dark elderberry drupes that follow. Spreads by root suckers into naturalized colonies 5-12 feet tall and wide; the flowers feed butterflies and the showy fruit feeds birds. The raw berries are not eaten fresh — they are cooked into jelly, pie, and wine.
