Boneset

Eupatorium perfoliatum
A large, hairy, clump-forming North American native perennial of wet meadows, low woods, stream banks, and prairies. Its most distinctive feature is the perfoliate foliage — pairs of wrinkled, opposite, lance-shaped leaves whose bases fuse around the hairy stem, so the stem appears to pass through the leaf. From July to September, flat-topped clusters of small, fluffy white flowers feed a wide range of bees, butterflies, and other pollinators, while all parts of the plant are toxic and bitter.

Senna hebecarpa
Wild senna
A tall, clump-forming native legume of eastern North America grown for showy mid- to late-summer clusters of gold-yellow flowers accented by dark, curving anthers. The pinnately compound leaves carry a club-shaped gland on the petiole, and the long-lived plants reach 4-6 feet. Bumblebees work the pollen-only flowers, hummingbirds visit, and the seeds feed birds including bobwhites.

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.

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.

Aronia melanocarpa
Black chokeberry
A drought-and-flood-tolerant native shrub of eastern North America with brilliant three-season interest — spring white-pink flowers, glossy black antioxidant-rich late-summer berries, and brilliant wine-red fall foliage — plus an extraordinarily wide cold-hardiness range (USDA 3a-8b). The berries are astringent fresh but the basis of a small but growing commercial industry (juices, wines, jams, supplements) for their exceptionally high anthocyanin content. Spreads by suckers; site where colony formation is welcome.
