Prairie dropseed
Sporobolus heterolepis
A clump-forming native warm-season prairie grass producing very fine emerald-green foliage in a graceful fountain habit + airy seed panicles in late summer with a distinctive cilantro-coriander fragrance when in bloom. Often described as the most elegant of the North American prairie grasses; long-lived (30+ years) and durable. Slow to establish — 2-3 years from seed — but unmatched in mature beauty.

Bouteloua curtipendula
Side-oats grama
A native warm-season prairie grass with a distinctive flower arrangement: the small purple-red spikelets hang in two rows on one side of arching wiry stems — the namesake "side-oats" habit. State grass of Texas; widespread in tallgrass + shortgrass prairie. Drought-tolerant once established; among the more drought-resistant native grasses for hot dry sites.
Bouteloua gracilis
Blue grama
A tough, fine-textured warm-season bunchgrass of the North American shortgrass prairie, named for its distinctive seed spikes that hang from one side of the arching stem like a comb or an eyebrow. Bluish-gray summer foliage forms dense low clumps that turn golden brown — sometimes orange and red — in autumn, while reddish-purple flowers rise above on slender culms in summer. Exceptionally drought- and heat-tolerant once established, it is a larval host for several prairie skipper butterflies and a seed source for granivorous birds.
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.
Yucca filamentosa
Adam's needle
A virtually stemless, broadleaf-evergreen native of central and eastern North America: a basal rosette of rigid, sword-shaped, spine-tipped leaves up to 30 inches long, fringed along the margins with the curly white threads that give the species its name. In early summer a flowering stalk shoots from the center to 5-8 feet, carrying nodding, bell-shaped, creamy-white flowers. Tough enough for poor sandy soil, heat, drought, and salt spray, it earns its keep as architectural structure in dry and seaside gardens.
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.
