Dwarf bluestar is the compact, well-behaved member of the clan, a tidy mound of upright stems and soft green leaves topped in late spring with clusters of powder-blue, star-shaped flowers. Often treated as a low form of the eastern bluestar, Amsonia montana stays small and shapely, a fine choice where the taller bluestars would sprawl.
The white-flowered form of swamp milkweed, Asclepias incarnata 'Ice Ballet' carries the same upright, well-mannered habit as the species but trades rosy pink for clusters of pure, cool white, held atop sturdy three-to-four-foot stems through summer. The effect is fresh and luminous in a moist border, and just as useful to wildlife.
Smooth aster is one of the cleanest and most dependable of the fall natives, and 'Bluebird' is among the best forms. Aster laevis 'Bluebird' builds an upright, vase-shaped clump of smooth, blue-green foliage, then opens, in late summer and fall, sprays of violet-blue daisies centered in gold, a generous late feast for bees and butterflies as the season winds down.
Summersweet, Clethra alnifolia, is one of the great fragrant natives of the eastern United States, a shrub of moist woods and pond edges whose white summer spikes carry a honey-and-clove perfume across the whole garden. Colonists called the plant Sweet Pepperbush, for the peppercorn-like seed heads that follow, and Summersweet, for the scent; the flowers even lather softly in water and once served as a field soap.
Clinopodium coccineum is a small, aromatic, semi-evergreen subshrub of the mint family, native to the deep, well-drained sands of the southeastern coastal plain, from Mississippi and Georgia down into Florida. The loose, open frame and small, spicy-scented leaves would earn a quiet place on their own, but the flowers are the event: showy scarlet tubes carried over a long summer season, held out like little trumpets that hummingbirds cannot resist.
The American smoketree, Cotinus obovatus, is an uncommon small to medium native tree, kin to the familiar European smoketree but bolder in leaf and rarer in gardens. The common name comes from the fruiting stage, when the loose, fuzzy flower panicles blur the whole crown into a soft haze of smoke. The broad, oval, blue-green leaves are noticeably larger than those of the European Cotinus coggygria, and they close the year in a spectacular blaze of orange, yellow, and red-purple, some of the finest fall color of any native tree.
The anise trees, genus Illicium, are aromatic broadleaf evergreens of the star-anise family, Schisandraceae, their Latin name meaning an allurement, for the spicy scent of the leaves. Illicium floridanum, the Florida anise, is a Southeastern native of shaded streambanks and moist ravines from Georgia to Louisiana, valued as one of the finest flowering evergreens for shade. This is a variegated selection, carrying the usual two-inch, starfish-shaped maroon flowers over foliage marked with a subtle, quiet green-on-green variegation.
Most mountain laurels are shrubs with presence, upright and woody and faintly aristocratic. 'Croft Carpet' flips the script. This rare, prostrate selection of Kalmia latifolia stays low and spreads into a dense evergreen mat, delivering the understory finish that designers chase in shade gardens: lush, deliberate, and quietly polished. A specimen at the JC Raulston Arboretum measured only about one foot tall while spreading many times as wide.
Manfreda maculosa carries the rugged beauty of the American Southwest into the garden. Known by a string of evocative names, Texas tuberose, spice lily, and rattlesnake agave, this striking plant hails from the arid country of Texas and northern Mexico, where the spotted leaves and tall, aromatic flower stalks have caught the eye of gardeners and naturalists for generations.
Monarda fistulosa, wild bergamot, is one of the great native perennials of the North American prairie, a hardy, aromatic member of the mint family loved for showy heads of lavender-pink and for a fragrance like oregano crossed with mint. The species grows wild in meadows, prairies, and open woods across most of the continent, and brings both vivid summer color and a deep well of history to the garden.
Sundrops make a gentle joke of their family. Oenothera fruticosa ssp. glauca belongs to the evening primroses, a tribe famous for opening at dusk and closing by mid-morning, yet the sundrops break ranks and bloom by day, holding cups of clear, satiny yellow wide open through the sunlit hours of late spring and early summer. The genus name comes from the Greek oinos, wine, and thera, to hunt or seek, an old and disputed reference to a European relative whose roots were once thought to give a taste for wine; the epithet fruticosa means shrubby, for the firm, upright stems, and glauca notes the blue-green bloom on the foliage.
Ptelea trifoliata, the hop tree or wafer ash, is a unique and underappreciated native, a small, bushy deciduous tree of eastern and central North America. Highly adaptable, the plant takes dry, rocky ground as readily as moist, well-drained sites, which makes the hop tree a fine choice for naturalized landscapes, pollinator gardens, and woodland edges.
These are the grandchildren of a legend. The Wye Oak of Wye Mills, Maryland, was the greatest white oak in the country, a single tree that stood more than four hundred and sixty years and served as Maryland's state tree until a storm finally brought the giant down in 2002. Quercus alba 'Grandchildren of Wye Oak' are seedling-grown descendants of that famous tree, carrying the bloodline of an American icon into gardens that have room for the long view.

Ruellia caroliniensis, the Carolina wild petunia, is a modest, long-blooming native that carries far more ecological weight than the quiet flowers suggest. From early summer into fall, a steady succession of lavender to violet-purple trumpets, each an inch or two across and lasting only a single day, opens along upright stems a foot or two high, replaced faithfully the next morning so that the plant is seldom out of bloom for months on end.
Salvia urticifolia, the nettleleaf sage, is an uncommon herbaceous perennial native to the Appalachians and the wider Southeast, grown for cool blue-to-violet flowers set off by a pair of white marks in the throat. The bloom comes in the freshness of mid to late spring, the flowers hovering above serrated, nettle-like leaves, and in a generous year a lighter second flush may follow in late summer.
A native aster with a regional accent. Most of the asters Americans plant are wide-ranging species that turn up from Maine to Texas and read essentially the same wherever they grow. Symphyotrichum grandiflorum is more particular, with a native range small and specific: the Atlantic Coastal Plain of Virginia and the Carolinas, plus the Piedmont of the Carolinas, and little more. A few hundred miles of sandy roadsides, dry pine-oak woods, abandoned fields, and forest edges from the Tidewater into the rolling country west of the fall line. For a gardener in the Carolinas or Georgia, this is one of the few asters that is genuinely here, a piece of the actual Atlantic Coastal Plain flora rather than a borrowed prairie species filling in for a missing native.
Florida yew is one of the rarest conifers in North America, a shrubby evergreen restricted to a single stretch of steep, cool ravines along the eastern bluffs of the Apalachicola River in the Florida Panhandle, and nowhere else on Earth. A shrub or small tree of the shaded understory, the plant carries flat, soft, dark-green needles and, on female plants, the fleshy scarlet arils that mark every yew.
