The garden's backbone: flowering trees, native and rare shrubs, and evergreens that hold their shape through every season. Many are Southeastern natives; others are quiet collector's plants you won't find at a big-box nursery, chosen for resilience and lasting, year-round interest.
'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.
'Admiral Semmes' is the best known and easiest to grow of the Dodd nurseries' Confederate Series of azaleas, a deciduous hybrid built for the Deep South's heat and humidity. The cross joins the native Florida azalea, Rhododendron austrinum, with the large-flowered Exbury hybrid 'Hotspur Yellow', and was raised at Dodd and Dodd Nurseries in Semmes, Alabama. The plant takes its name from the Confederate admiral Raphael Semmes, and went on to win the Georgia Gold Medal in 2007.
'Colonel Mosby' is among the most arresting of the Dodd nurseries' Confederate Series of native azaleas, a deciduous hybrid raised at Dodd and Dodd Nurseries in Semmes, Alabama. The cross, made by Bob Schwindt, joins the golden Florida azalea, Rhododendron austrinum, with the large-flowered Exbury hybrid 'Hotspur Yellow', and the plant takes its name from John Singleton Mosby, the Confederate cavalry commander known as the Gray Ghost.
This native azalea is a hybrid of two well-loved wild species, the Cumberland azalea, Rhododendron bakeri, of the southern Appalachians, and the swamp azalea, Rhododendron viscosum, of wet woodland edges across the East. From the Cumberland azalea the cross takes warm color and a rounded, ball-shaped truss; from the swamp azalea, whose name viscosum means sticky, for the glandular, clammy surface of the flowers, the hybrid takes adaptability to humid ground and a late season of bloom. The genus name Rhododendron means rose tree in Greek.
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.
'Balsaminaeflorum' is a dwarf evergreen Satsuki azalea, an old Japanese cultivar of Rhododendron indicum grown for flowers that look less like azaleas than like tiny roses. Each bloom is fully double, packed with forty or more petals and carrying neither pistil nor stamens, so the flower is all soft, ruffled color. The cultivar name means balsam-flowered, a nod to the double blooms of the garden balsam, while indicum, meaning of India, is an old misnomer for a plant that is in fact Japanese.
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.
A three-hundred-year-old Japanese garden azalea that does not look quite like a rhododendron, does not look quite like an azalea, and does not really look like anything else. The leaves are narrow green ribbons, three to five millimeters wide and a couple of inches long, closer to willow or fine grass than to the broad rounded foliage of an ordinary tsutsuji. The flowers, opening in late April and May, follow the same grammar: deeply divided into long strap-like petals in lilac-pink to lavender-rose, tangled and knotted at first, then unfurling slowly into a shape that reads, depending on the eye, as a crane fly, a spider, or a piece of decorative garnish. Wabi-sabi made evergreen.
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.
'Koromo Shikibu' is the spider azalea, and there is nothing else in the genus quite like the flower. Instead of the usual funnel, each bloom splits into narrow, strap-like petals that spread apart like the legs of a starfish or a spider, lavender to purplish-pink, spotted darker at the base, and carried in such profusion in spring that the whole shrub seems to shimmer. Once seen, the flower is not forgotten.
'Addison' began as a chance seedling of the Alabama azalea, Rhododendron alabamense, and grew into something none of the parents quite predicted. Surely a hybrid, though the exact parentage remains unknown, the plant carries large, dense, dome-shaped terminal clusters that blend shades of yellow, pink, and white in a single truss, a multicolored effect striking enough that the selection first went by the name 'Stunning'. Charles Webb, a good friend of Woodlanders, spotted and selected the seedling in Florida, and the plant now carries the name of one of his young granddaughters.
'Casille' arose spontaneously, a chance hybrid among three of the southeastern native azaleas: the white, lemon-scented Alabama azalea, Rhododendron alabamense; the fragrant pink Piedmont azalea, R. canescens; and the fiery, unscented Oconee azalea, R. flammeum. From that three-way mingling came a deciduous shrub that blooms in mid-spring in a lively pastel blend, the flowers shifting through pink, white, and soft yellow with a subtle sweetness inherited from the fragrant parents. An exclusive Woodlanders introduction, the plant was named by George Mitchell for his wife.
