Plants that turn their faces to the light. This is the roll call for the open, sun-struck parts of the garden, the borders and banks that bake from morning to evening, where the toughest, brightest, most floriferous plants do their best work.
Dwarf chinquapin oak is the oak for gardeners in a hurry, a small, shrubby white oak that starts bearing sweet acorns while still only a few feet tall. Where most oaks make you wait a generation, this one fruits at three to five years old and crops nearly every year after, a rare and useful trick. The plant grows as a rhizomatous, colony-forming shrub or small tree of ten to twenty feet, clothed in glossy, chestnut-like leaves with wavy, blunt teeth.
Rhaphiolepis umbellata is the hardiest of the Yeddo hawthorns, an evergreen member of the rose family (Rosaceae) that grows wild on the sea cliffs and coastal thickets of Japan and Korea. The genus name joins the Greek raphis, a needle, with lepis, a scale, a nod to the narrow bracts beneath the flower clusters, while the species epithet umbellata describes the way the blossoms gather into rounded, umbel-like heads. Western gardeners know the shrub as Indian hawthorn, a slightly misleading name, since the plant hails from East Asia rather than the subcontinent and is no true hawthorn at all.
'Great Balls of Fire' belongs to the celebrated line of Aromi azaleas, the life's work of Dr. Eugene Aromi, a University of South Alabama education professor who set out in the late 1960s simply to help the azaleas in his Mobile front yard survive the Gulf Coast's brutal heat and humidity. What began as a backyard experiment grew into one of the great American breeding programs. From 1971 onward Aromi crossed cold-hardy Exbury and Knap Hill azaleas with tough southern native species, chief among them the Florida azalea, Rhododendron austrinum, chasing large, fragrant, heat-proof deciduous flowers. He made more than a thousand crosses and raised over fifty thousand seedlings before his death in 2004, and roughly a hundred of the best were named. This is counted among them.
Sunbow Solar Flare is the patented name for the azalea catalogued as Rhododendron 'QbackB' (U.S. Plant Patent 27,083), a deciduous native hybrid bred for the very conditions that defeat most azaleas. The plant traces to a deliberate cross made in 1984 by Robert Edward Lee in Folsom, Louisiana, who set out to combine the fragrance and vivid color of the Gulf Coast's own Florida azalea, Rhododendron austrinum, with the substance of the Exbury hybrids. A seedling from austrinum open-pollinated with the hybrid 'Gibraltar' was crossed onto 'Chetco', and from that union Lee selected this standout in 1990.
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.
'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.
'Stonewall Jackson' is one of the Dodd nurseries' celebrated Confederate Series of deciduous native azalea hybrids, introduced by Tom Dodd Jr. and Tom Dodd III of Semmes, Alabama. The plant is a cross between the Exbury azalea 'Hotspur Yellow' and the native Florida azalea, Rhododendron austrinum, uniting the size and substance of the English hybrids with the fragrance and Gulf Coast toughness of the wild Southern species.
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.
'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'.
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.
The swamp azalea, Rhododendron viscosum, ordinarily opens white; this selection breaks pink. 'Roseum' is a rose-flushed form of the familiar native, chosen and introduced by Woodlanders from a plant of Aiken County, South Carolina provenance, a home-ground selection that carries the sweet, clove-like fragrance of the species in a warmer color. The swamp azalea ranges widely across the eastern United States, from the Gulf Coast north into New England, threading the wet margins of swamps, bogs, and stream banks where few other flowering shrubs will follow.
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.
'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.
This hardy hybrid azalea is a piece of Woodlanders history, a deliberate cross made by the nursery's late founder, Robert Mackintosh. Mackintosh crossed the native roseshell azalea, Rhododendron prinophyllum, with the old hybrid group known as R. x kosterana, or mollis azalea, and the result is an upright, large-flowered deciduous shrub carrying bold orange trusses each marked with a splash of yellow.
Fragrant sumac is a versatile deciduous shrub native across much of the eastern and central United States, where the plant threads scattered woodlands, rocky slopes, and open banks. The trifoliate leaves, often mistaken at a glance for poison oak, are entirely harmless, and a crushed leaf releases the clean, lemony-resinous scent that gives the plant every one of the common names, from fragrant sumac to skunkbush, depending on the nose. The genus name Rhus is the old Greek and Latin word for the sumacs, and the epithet aromatica names the scent directly.

The pink Cherokee rose is a big, vigorous, early-flowering climber grown for one glorious effect: large, single, silvery-pink flowers, up to four inches across, each a simple five-petaled saucer lit by a central boss of gold stamens. Where the true Cherokee rose blooms white, this one blooms in clear, soft pink, and opens early, in the first warm reach of spring, ahead of most roses.
Rubus irenaeus is a raspberry that has forgotten how to be a bramble. Rather than the arching, thorny canes of the fruiting kinds, the plant trails flat along the ground on downy, weakly prickled stems, laying down a dense evergreen carpet of large, rounded, coltsfoot-like leaves, each six inches or more across, dark and glossy above and felted pale brown beneath. Few groundcovers of any kind bring foliage this bold to deep shade.
Rudbeckia nitida is a tall, luminous coneflower that trades the coarse hairiness of the common black-eyed Susans for smooth, glossy, dark green leaves and hairless stems, the shining foliage that gives the species a name. From a leafy base rise slender stems three to five feet tall, each carrying a large yellow daisy whose soft rays droop back from a raised, greenish-brown central cone, blooming through the heat of mid to late summer.
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.
