Smooth sumac is a bold, colony-forming native shrub of the eastern and central United States, in time reaching the scale of a small tree, and one of the finest plants going for a hot, dry, sunny site where little else will thrive. The long, pinnately compound leaves give an almost tropical texture through summer, and the plant spreads by root suckers into broad, picturesque colonies, or can be held to a single tree-like specimen where the suckers are controlled.

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.

The swamp rose is one of the few roses that truly loves wet feet, a tall, graceful native shrub of the eastern United States that grows wild along pond edges, streambanks, and in the low, seasonally flooded ground where garden roses would drown. Reaching four to eight feet on arching, sparingly thorny canes, the plant opens fragrant, single, clear pink flowers through the summer, each a simple five-petaled saucer around a boss of gold stamens, a soft, untamed beauty far from the tidy hybrid tea.
Rudbeckia fulgida var. fulgida is the true orange coneflower, the wild species that stands behind the famous 'Goldsturm', quieter, finer, and later to bloom than that celebrated garden child. From a low clump of dark, roughly hairy leaves rise branching stems two to three feet tall, each ending in a small golden daisy about two inches across, the deep yellow rays set around a low dome of brown-black. Where many of the black-eyed Susans have blazed and faded by August, the orange coneflower is only getting started, carrying many small flowers from late summer well into October.
Rhododendron alabamense, the Alabama azalea, is one of the loveliest and, by wide agreement, one of the most powerfully fragrant of all the wild deciduous azaleas of the Southeast. The species grows in hardwood forests and along dry slopes and ridges from north-central Alabama east through western Georgia and into South Carolina, where in mid spring the woods fill with the scent of lemon. Clusters of six to ten white, funnel-shaped flowers, each marked with a clear yellow blotch and finished with long, arching stamens, open just before or alongside the emerging leaves. The genus name Rhododendron means rose tree in Greek, while azalea derives from azaleos, meaning dry, a nod to the well-drained upland ground these shrubs favor.
Rhododendron arborescens, the sweet or smooth azalea, is one of the hardiest and most graceful of the native white azaleas, a tall, loosely branched deciduous shrub of the eastern mountains and piedmont. The common name smooth azalea points to the hairless, glossy twigs and leaves that set the species apart from woollier kin, while sweet azalea speaks to the flowers, which pour out a rich heliotrope perfume. The species epithet arborescens is Latin for becoming tree-like, a fair description of an old plant that can reach ten to eighteen feet, and the genus name Rhododendron means rose tree in Greek.
Rhododendron atlanticum, the coastal or dwarf azalea, is a low, colony-forming native of the open pine woods and sandy flatwoods of the mid-Atlantic and Carolina coastal plain. Unlike the tall wild azaleas of the mountains, this species stays close to the ground, often no higher than the knee, and spreads by underground runners, or stolons, into broad, drifting colonies. The bluish, glaucous foliage is a hallmark, cool and sea-gray, and the species name atlanticum simply marks the plant's home along the Atlantic seaboard. The genus name Rhododendron means rose tree in Greek; azalea comes from azaleos, meaning dry, a fitting root for a shrub of sandy, well-drained ground.
Rhododendron austrinum, the Florida azalea, is among the earliest and most powerfully fragrant of all the wild deciduous azaleas of the Deep South. Native to the Florida Panhandle, southern Georgia, southern Alabama, and into Mississippi, the species haunts open pine woods, ravine slopes, and river bluffs, often growing in sandy, acidic ground beneath tall longleaf pines. The species name austrinum simply means southern, a fitting label for an azalea so at home in the Gulf Coast heat, and the genus name Rhododendron means rose tree in Greek.
Rhododendron austrinum 'Don's Variegated' is a rare variegated form of the native Florida azalea, carrying the wild flame azalea of the Gulf states but brushed with a fine tracing of gold along each leaf edge. The selection was discovered by Don Jacobs, the noted Georgia plantsman behind Eco-Gardens in Decatur, who found among seedlings of R. austrinum a plant whose foliage held light even before the flowers arrived. Variegation is uncommon in the native azaleas, which makes this a genuine collector's plant.
'Millie Mac' is a wild-selected native azalea from the damp hollows of Escambia County, Alabama, where Floyd McConnell found this plant as a distinctive limb sport on a wild shrub and propagated it for a beauty all its own. Related to the Florida azalea, Rhododendron austrinum, the selection shows white-margined flowers that hint at a touch of R. canescens in the background, and the lineage remains a matter of pleasant debate among native-azalea growers.
'Reagan' is a richly colored selection of the Florida azalea, Rhododendron austrinum, chosen in the wild in Florida near the Apalachicola River, the great blackwater river whose ravines shelter some of the Southeast's rarest plants. Where the typical Florida azalea runs to clear gold and orange, this form pairs yellow petals with deep reddish-pink buds and flower tubes, so that from a distance the whole shrub takes on a warm, red-flushed glow uncommon in the species.
'Varnadoe's Moonbeam' is a luminous early-spring selection of the Florida azalea, Rhododendron austrinum, prized for a soft, glowing color less common in the species. Rather than the fiery orange of many forms, the flowers open in clear golden yellow brushed with apricot and orange in the throat, over reddish tubes, a warm but refined coloring that seems to catch and hold the light, moonlit rather than blazing, against the still-bare spring woodland.
This is a rare and radiant selection of the Florida azalea, Rhododendron austrinum, chosen for flowers of pure, clear yellow. Where the species usually runs to golden-orange, this form holds a clean, buttery, luminous yellow, a color that lights up the spring woodland like sunshine slipping through the canopy. For gardeners and collectors who love the native azaleas, a truly pure-yellow austrinum is an uncommon prize.
Rhododendron canescens, the Piedmont azalea, is very likely the most widespread of all the wild deciduous azaleas of the Southeast, ranging through the Piedmont, coastal plain, and stream edges from the mid-Atlantic to the Gulf. Country people have long called the plant the Southern pinxter or simply wild honeysuckle, for the sweet, honeysuckle-like scent of the flowers. The species name canescens means becoming gray or hoary, a reference to the soft gray down that coats the undersides of the leaves and the new growth.
'Clyo Red' is a striking red-flowered selection of the native Piedmont azalea, Rhododendron canescens, a species usually seen in soft pink and white. Here the wild pink is deepened to a rich cherry-red, an uncommon and eye-catching tone among the native azaleas, carried on the same fragrant, early-spring frame that makes the Piedmont azalea so beloved. The name points to Clyo, a small community in Effingham County, Georgia, near the plant's Southern home.
'Varnadoe's Pink' is a choice dark-pink selection of the native Piedmont azalea, Rhododendron canescens, chosen and grown by the late Aaron Varnadoe of Colquitt, Georgia, a great native-azalea grower and genuine Southern character. Where the wild species varies from pale to deep pink, this selection holds a rich, abundant dark pink, and the plant has become a popular favorite for that reliable color and a good habit and foliage. The selection is sometimes sold under the name 'Varnadoe's Phlox Pink'.
Rhododendron colemanii, the Red Hills azalea, is one of the most recently recognized of all the native deciduous azaleas, first described as a distinct species only in 2008. For years the plant was folded in with the Alabama azalea, Rhododendron alabamense, which blooms earlier and holds consistently white, yellow-blotched flowers; the Red Hills azalea, by contrast, flowers later and in a wider range of color. The species takes its home ground from the Red Hills country of the inner coastal plain, a narrow range across southwest Georgia and southern Alabama.
Among the most beloved of the eastern wild azaleas, Rhododendron periclymenoides drifts through the open woods and swamp margins of the eastern United States from New Hampshire and Massachusetts south to South Carolina, Tennessee, and Alabama, opening clouds of pink bloom just as the woodland wakes in spring. This selection breaks from the ordinary pink of the species: a soft lavender-purple color form discovered in Lancaster County, South Carolina, and introduced by Woodlanders, uncommon in the wild and rarer still in cultivation. Botanists once filed the species under the name Rhododendron nudiflorum, and the plant still answers to that older label in many an old garden book.
The native deciduous azaleas of the southeastern United States bloom in a long relay, from the pinxters and Piedmont azaleas of March through the flame azaleas of April and May and on into July with the red of Rhododendron prunifolium. And then, once most gardeners have closed the azalea chapter for the year, Rhododendron serrulatum opens. Hammocksweet azalea is the last of the line, flowering in August and September and sometimes later still.
The glaucous swamp azalea is a native deciduous shrub of the wetland South and the eastern seaboard, a blue-leaved form of Rhododendron viscosum, the widespread swamp azalea that ranges from the Gulf Coast north into New England. The variety glaucum sets the plant apart with foliage washed in a soft blue-green, most striking on the leaf undersides, which flash pale as a breeze turns them. Where many shrubs falter, this azalea thrives in the consistently moist, even boggy ground of swamps, marshes, and stream banks.
