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.
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.
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.
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.

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.
Sabal 'Birmingham' is one of the hardiest fan palms an American gardener can grow, and the palm owes its survival to Woodlanders. Well-established specimens come through USDA Zone 7, deep into country where an ordinary cabbage palm needs coddling and near-perfect siting just to limp along. Broad, costapalmate, deep green fronds rise on a stout, slowly building trunk, giving the unmistakable palm silhouette hundreds of miles north of where the family usually stops.
Sabal etonia, the scrub palmetto, is a small fan palm found nowhere in the world but Florida, where the palm is a signature of the sand pine scrub, most abundantly along the ancient dunes of the Lake Wales Ridge. The specific epithet etonia comes from the Etonia scrub of Putnam County, the country where the species was first collected, so the botanical name carries a Florida place with it.
Sabal mexicana, the Texas Palmetto, is a large, robust fan palm once known as Sabal texana. In the United States the palm is native to the lower Rio Grande Valley of Texas, and formerly ranged northward along the south Texas Gulf coast, while the wider distribution reaches through eastern Mexico into Central America. The species resembles the cabbage palmetto of the Southeast but reads as heavier and more massive, and the much larger seed is the surest way to tell the two apart.
Sabal palmetto, the Cabbage Palmetto, is the classic palm of the Southeastern coast and the State Tree of both South Carolina and Florida. Blue-green, costapalmate (fan) leaves crown a straight trunk that thickens to about a foot and a half across, and the whole reads as the very image of the coastal South. The palm grows commonly to around thirty feet and climbs considerably taller in Florida.
Salix eriocephala, the heart-leaved or Missouri River willow, is a graceful native shrub, sometimes a modest multi-stemmed tree, of riverbanks and wet meadows across northern and eastern North America. The plant rises on several trunks clad in coarse gray bark, reaching roughly eight to a dozen feet in the garden and more in wild thickets, and the epithet eriocephala, meaning woolly-headed, points to the soft, silky catkins that give the willow much of its charm.
Salvia urticifolia, the nettleleaf sage, is an uncommon herbaceous perennial native to the Appalachians and the wider Southeast, grown for cool blue-to-violet flowers set off by a pair of white marks in the throat. The bloom comes in the freshness of mid to late spring, the flowers hovering above serrated, nettle-like leaves, and in a generous year a lighter second flush may follow in late summer.
Few native trees announce themselves as cheerfully as Sassafras albidum, whose leaves come in three shapes on the same branch: an unlobed oval, a two-lobed mitten, and a three-lobed silhouette like a splayed hand. A member of the laurel family, Lauraceae, and kin to bay, cinnamon, and spicebush, sassafras carries aromatic oils in every part, so that a snapped twig or crushed leaf releases a warm, root-beer sweetness. The common name traces back through Spanish to the colonial Southeast, where the tree was among the first American plants shipped to Europe as a marketable medicine.
Showy skullcap earns the flattering half of the common name honestly: of the eastern woodland skullcaps, Scutellaria serrata carries some of the largest and most richly colored flowers. The genus name comes from the Latin scutella, a little dish or tray, for the small pouch on the upper side of the seed capsule that gives every skullcap its family resemblance. A member of the mint family, Lamiaceae, showy skullcap keeps the square stems and paired leaves of that clan, here with bright green, boldly toothed foliage often edged in wine-red.
Saw palmetto is the signature palm of the Deep South, a low, fan-leaved evergreen that carpets the pine flatwoods, scrub, and coastal dunes from the Carolinas through Florida and along the Gulf. The genus honors the American botanist Sereno Watson, and the species name repens, creeping, describes the sprawling habit, while the common name comes from the fierce saw-toothed edges that arm each leaf stalk. Serenoa repens is the only species in the genus, and among the most abundant plants in Florida.
