Staghorn sumac is a bold native shrub or small tree of the northeastern United States and Canada, growing fifteen to thirty feet on stout, forking stems clothed in fine velvety hairs, the texture and antler-like branching that give the plant the name. The big, pinnate leaves are bright green through summer and turn a spectacular blend of yellow, orange, and red in fall, one of the great autumn shrubs of the eastern flora.

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.

The first surprise of Quercus phellos is that nobody believes they're an oak. The leaves are narrow and untoothed, willow-like, finer than an oak has any right to be, and they turn soft yellow before they fall; only the acorns, small and round and produced by the thousand, give the game away.
Ilex verticillata ‘Red Sprite’ is winterberry shrunk to garden size and cranked up in intensity. Where much of the landscape fades to gray, this compact native holly turns into a beacon, the bare stems packed with heavy clusters of large, glossy scarlet berries that color in fall and cling deep into winter, a living ember at the pond’s edge or against fresh snow.
Ironweed earns the name twice over. The stems are stiff enough to stand through a hurricane season without staking, and the seedheads that follow the flowers rust to the exact color of weathered iron. But the reason to grow Vernonia noveboracensis is the purple: not the tidy lavender of garden asters but a saturated, almost fluorescent violet that arrives in late July and holds into October, riding five to eight feet up on strong green stems above a mass of long, finely toothed leaves. Few native perennials carry a color this pure so late in the year.
In the dim, humid hush of a Southern swamp or the shaded edges of a woodland stream, Osmunda regalis var. spectabilis, commonly known as the American royal fern, stands as a silent monarch. This grandiose fern, native across eastern North America, unfurls towering fronds that burst upward in graceful rosettes, often reaching 3 to 6 feet tall with a spread of 2 to 3 feet. The distinctive, dignified look has earned these ferns the moniker flowering fern, a nod to the upright, spore-laden fertile fronds that crown each spring with tassel-like clusters before maturing to russet-brown.
Symphyotrichum oblongifolium, the aromatic aster, saves the best of the season for last. Long after most perennials have folded, this tough native throws up a low, spreading mound of stiff, well-branched stems and buries the whole clump under small violet-blue daisies, each lit with a bright gold eye, from early fall well into November. The show arrives just as the garden goes quiet, and the flowers hum with the last bees and butterflies of the year.
A rain lily that flowers on a whim of the weather, and a plant that spent nearly forty years under the wrong name. Zephyranthes macrosiphon is a bulbous perennial of the amaryllis family, native to eastern Mexico, grown for vivid rose-pink flowers that open as if overnight after warm-season rain.
There is a small lie in the name. Sanguinea means blood, and yet the iris in front of you is blue, or blue running toward violet, with only a wine-dark deepening in the falls to argue the case. The botanists felt the strain too: Carl Thunberg first tried to file the plant as Iris orientalis in 1794, found that name already taken, and the species waited until 1813 for the one carried since. The Japanese never bothered with Latin. To them the flower is ayame, one of the three irises of early summer, threaded through a thousand years of poetry and arriving in that uncertain seam where the old poets could never quite agree whether spring had ended or summer begun.
Dryopteris ×remota, the remote wood fern or scaly buckler fern, is one of those quiet accidents of nature that turns out better than anything a breeder set out to make. The fern is a naturally occurring hybrid between the scaly male fern, Dryopteris affinis, of western Europe and the British Isles, and the broad buckler fern, Dryopteris expansa, of cooler northern woods. From the affinis parent the hybrid took shaggy stalks thickly clothed in golden-brown scales; from expansa, the fine, lacy cut of the frond. The epithet remota, meaning scattered or spaced apart, points to the way the lowest segments stand a little distant from one another along the frond, a subtle tell that separates this fern from the crowd of look-alike wood ferns.
This one comes with a paper trail. 'Illustris' was first described in 1873 by William Bull, the Chelsea nurseryman, who listed the plant as Alocasia illustris in his catalogue of new and rare plants and sold them out of his glasshouses at 536 King's Road. Nobody knows quite where they came from. Colocasia esculenta is a restless, variable species, and Bull had rivers of tropical material moving through the place, so the likeliest story is that he caught a dark-leaved sport among the green, liked what he saw, and kept dividing the stock. Every 'Illustris' in cultivation descends from that one Victorian decision. A 150-year-old clone, still in production.
For a week or two in late spring, the Chinese fringetree vanishes under what looks like a fresh fall of snow. Chionanthus retusus is a deciduous small tree of eastern Asia, native across China, Korea, Japan, and Taiwan, and the whole performance turns on the flowering: dense, lacy panicles of narrow, strap-shaped petals, pure white and softly fragrant, break over the entire canopy until the leaves all but disappear beneath the froth. The genus name records the effect exactly, from the Greek chion, snow, and anthos, flower.
The overcup oak is named for a small piece of botanical theater: an acorn so nearly swallowed by its cup that only the tip shows, sealed up as if against the floodwaters the tree was born to. Quercus lyrata is a creature of the southern bottomlands, the broad floodplains and backswamps from the Mississippi Delta to the Carolina river bottoms, standing through the cycles of flood and drawdown that drown lesser trees.
Madeira vine is a fast, twining, deciduous climber with fleshy, heart-shaped leaves and sprays of tiny, fragrant cream-white flowers in late summer and fall. Anredera cordifolia climbs by winding tuberous stems, and a warty crop of aerial tubers along the stems, some as large as a small potato, is the surest mark of the plant and a ready means of increase.

Piloblephis rigida, wild or Florida pennyroyal, is a compact evergreen native mint from the sandy scrublands and pine flatwoods of Florida. The plant forms a low, tidy mound of fine, needle-like foliage that carries a clean, resinous, minty fragrance, released at a brush of the hand or on a warm afternoon in the sun.

Sabal tamaulipensis is a solitary fan palm from the dry limestone hills of northeastern Mexico, where the species climbs the San Carlos Mountains of Tamaulipas and neighboring Nuevo Leon. Stiff, rounded, blue-green fans are held on arching stalks above a trunk that stays short for many years, so young plants read as a fountain of palmate leaves close to the ground. In habitat the palm can eventually reach fifteen to twenty feet, though cultivated plants are slow and often stay compact, and older specimens sometimes recline on a horizontal trunk rather than standing straight. Small, fragrant, creamy flowers give way to round black fruit in the wild.
Some plants arrive with a pedigree, and some arrive with a person. This one came to us from Ken Wurdack, a botanist at the Smithsonian's National Museum of Natural History, and his work centers on the systematics and evolution of the spurge family, Euphorbiaceae. He's the sort of botanist who describes entirely new genera in the tribe Hippomaneae, which happens to be the exact tribe Sebastiania sits in. So this is a spurge handed over by a man who names spurges for a living, which is about the best reference a euphorb could ask for.
Gymnocladus dioicus, the Kentucky coffeetree, is a bold, handsome native shade tree that keeps its own unhurried calendar, among the last trees to leaf out in spring and the first to stand bare in fall. That long leafless season gave the tree a curious name, which means naked branch, and the winter silhouette of thick, blunt, sculptural limbs is a feature in itself. Hillier's great manual calls the Kentucky coffeetree one of the most handsome of all hardy trees, and few who grow one would disagree.
Amorpha fruticosa, the false indigo bush, is the largest and most widespread of the native false indigos, a fast, open, deciduous shrub that carries long spires of tiny deep blue-purple flowers, each lit with a single vivid orange anther, at the branch tips in late spring and early summer. From a suckering base rise arching stems six to twelve feet tall, clothed in soft, ferny, pinnate leaves that give off a clean, resinous scent when crushed. In full bloom the whole shrub seems to smoke with color, and the flower spikes hum with bees.

Juglans nigra, the eastern black walnut, is one of the great trees of eastern North America, a towering, long-lived hardwood native from the Appalachians and Midwest to the Mississippi Valley, most at home in deep, rich, moist but well-drained soils along river bottoms and fertile uplands. Large pinnate leaves cast a broad, airy shade in summer, leaf out late in spring, and drop early in fall to a soft gold, making way for the tree's most famous gift, the crop of hard-shelled nuts.
