Few trees carry the weight of the South the way the live oak does. Quercus virginiana is the massive, broad-spreading, long-lived evergreen oak of the coastal plain from Virginia to Texas, the tree of avenues and old plantations, of moss-hung branches reaching low and wide over generations of the same ground. Given room and time, a live oak grows far wider than tall, the great limbs sweeping out and often down to rest on the earth, and the whole tree becomes a piece of living architecture. Georgia named the live oak the state tree, and ancient specimens are landmarks across the Deep South.
The Southern live oak needs no introduction in the coastal South, where the great, spreading, moss-draped evergreens are as much a part of the landscape as the light. Quercus virginiana 'Bok Tower' begins from that familiar species but carries an unusual story and, perhaps, an unusual future.
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.
Flame azalea is the showiest of all the native azaleas, and the one that stops hikers in their tracks on the Appalachian balds each June. The large, funnel-shaped flowers open in a fiery range that runs from clear yellow through gold and apricot to blazing orange and scarlet, carried in loose trusses just as the new leaves expand. For all that color the flowers are, unusually, without scent, but nothing about a flame azalea in full bloom feels the lack.
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.
The Oconee azalea is the flame azalea of the lowlands, and for a Southern gardener that difference matters. Where the mountain flame azalea pines for cool Appalachian summers, this Piedmont cousin was born to the heat, thriving in the clay hills and stream bluffs of middle Georgia and South Carolina and taking the humidity of the Deep South in stride. The reward is the same fire in the flower: bright orange to orange-red trusses, sometimes shading to salmon or gold, opening in mid-spring.
Pinxterbloom is the wild azalea of the eastern woods, a hardy native that hangs its soft pink flowers along the branches in mid-spring, just before the leaves catch up. The funnel-shaped blooms, pale pink to nearly white, throw long curving stamens well past the petals, giving the whole shrub a hazy, spidery lightness, and carry a faint sweet scent on a warm day. Few native shrubs say spring so plainly.
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.
