'Aromi Sunrise' is a deciduous azalea from the storied breeding program of Dr. Eugene Aromi, the University of South Alabama professor who spent decades teaching heat-shy azaleas to flourish along the Gulf Coast. Introduced in 1987, this hybrid marries the bold Knap Hill azalea 'Hiawatha' with the native Florida azalea, Rhododendron austrinum, so the plant inherits both the size and clarity of the English strains and the toughness and fragrance of a southern wildflower. The result is exactly what Aromi chased across more than a thousand crosses: a large-flowered, sweet-scented, heat-tolerant azalea for gardens where the classic mountain sorts fail.
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.
'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.
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.
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.
Salvia 'Anthony Parker' is a big, late-blooming hybrid sage with a charming South Carolina origin. The plant arose as a chance seedling in the Beaufort garden of the plantswoman Frances Parker, a cross between Salvia leucantha 'Midnight' and the pineapple sage Salvia elegans, and Frances rescued the young seedling from the path of the mower and named it for her grandson Anthony, then a year old, in 1994. From that lucky reprieve came one of the best late-season salvias for the South.
Serissa foetida 'Kowloon', now more correctly placed as Serissa japonica, is a small, dense evergreen shrub known by a string of affectionate names: snow rose, tree of a thousand stars, and Japanese boxthorn. The genus stands alone in the coffee family, Rubiaceae, a surprising cousin to coffee, gardenia, and pentas. The unlovely species name foetida records the one fault, since bruised leaves and roots give off a faintly unpleasant smell, a small price for so much charm.
Royal catchfly wears the most electric red in the native flora. Silene regia sends up leafy, upright stems two to four feet tall, topped in mid to late summer with loose clusters of brilliant scarlet, star-shaped flowers, each with five deeply notched petals. Few prairie plants flower in true red, and fewer hold that color through the heat of July and August, which makes this native a genuine standout.
Blue-stemmed goldenrod is the goldenrod for shade. Where most of the clan demand open sun, Solidago caesia threads through the dappled light of the eastern woodland, arching slender, blue-purple stems that carry small, brilliant yellow flowers packed into the leaf axils, so the bloom runs the whole length of each stem like a garland. That habit gives the second common name, wreath goldenrod, and the late-summer to autumn color arrives just as the shade garden begins to fade.
Styrax obassia, the fragrant snowbell, is the bold-leaved cousin of the more familiar Japanese snowbell, a small deciduous tree from the mountain woodlands of Japan, Korea, and China. Where Styrax japonicus hides small bells beneath fine, layered branches, the fragrant snowbell wears large, rounded, almost tropical leaves up to eight inches across, and hangs long, drooping chains of white, bell-shaped flowers that carry a sweet perfume through the late-spring garden.
In the open oak-hickory woodlands and fire-maintained savannas that once covered the upland South, Georgia aster was a fixture, a late-season native sending up violet-blue flowers in October and November at the precise moment when almost everything else had finished. That landscape is largely gone now, and the aster went with most of it.
Copper Canyon daisy is a big, aromatic, autumn-flowering marigold from the mountains of southern Arizona and adjacent northern Mexico, grown as much for the scent as the show. Brush against the finely divided, fern-like foliage and the plant releases a strong, distinctive fragrance, a mix of citrus, anise, and marigold that some find intoxicating and others frankly pungent. Tagetes lemmonii builds a soft, shrubby mound three to four feet high and wider still.
Pond cypress is the quieter of the two native bald cypresses, a deciduous conifer closely related to the more widespread Taxodium distichum but smaller, tidier, and distinct in leaf. Where bald cypress wears soft, feather-like foliage, pond cypress carries fine, scale-like leaves pressed close and ascending along the shoots, giving the young tree a narrow, almost columnar, pyramidal outline.
Cape honeysuckle is a rangy, vine-like evergreen shrub from southern Africa, grown for glossy, compound leaves like a trumpet vine's and, above all, for the showy clusters of orange to orange-red tubular flowers that hummingbirds and, in the wild, sunbirds cannot resist. A member of the trumpet-vine family, Bignoniaceae, the plant can be trained up a support, clipped into a loose informal hedge, or left to cascade over a wall or bank.
Tulbaghia violacea, the plant gardeners know as society garlic, is a clump-forming perennial from the summer-dry grasslands of southern Africa, ranging from the Little Karoo through the Eastern Cape to KwaZulu-Natal. The genus honors Ryk Tulbagh, the eighteenth-century Dutch governor of the Cape of Good Hope, while the species name violacea simply means violet, for the color of the flowers. The common name is a small joke: the leaves carry a clear garlic scent, but a gentler, more sociable one than true garlic, said to be polite enough for company.

'Homestead Purple' is one of the great garden discoveries of the modern South, a trailing perennial verbena found not in a breeding plot but by the side of a Georgia road. In the early 1990s the University of Georgia horticulturists Michael Dirr and Allan Armitage drove past a sheet of royal-purple bloom at an old homestead, turned around, and gathered cuttings from a plant the owner said had simply grown there for years. That roadside find became one of the most popular perennials in American gardens, and the botanists gave the plant the name of the place it was found.
Few shrubs wear a name as plainly as this one. Odoratissimum is Latin for the most fragrant, the sweetest-scented, and sweet viburnum earns the superlative in late spring, when conical panicles of tiny white flowers open across the canopy and carry a soft, honeyed perfume on warm air. A member of the moschatel family, Adoxaceae, and a cousin of the elders and the arrowwoods, Viburnum odoratissimum ranges as a wild plant from the Himalayan foothills of India through Myanmar, Thailand, and Vietnam to China, Taiwan, Korea, and Japan, a broad Asian sweep that hints at the plant's easy adaptability in the warm garden.
A tough, glossy evergreen born of two Chinese parents and a Prague nursery. Viburnum x pragense is the cross of the leatherleaf viburnum, Viburnum rhytidophyllum, with the service viburnum, Viburnum utile, first raised by the plantsman Josef Vik at the Municipal Nurseries of Prague in 1955 and named for the city in 1959. The epithet pragense simply means of Prague, a rare instance of a garden hybrid carrying a birthplace rather than a botanist.
There are few sights more stirring than a wisteria in bloom, and 'Amethyst Falls' offers all the romance without the unruly habits of the Asian cousins. This refined selection of the native American wisteria, Wisteria frutescens, pours out cascades of fragrant, lavender-violet blossoms in late spring, with smaller flushes through summer, a soft echo of springtime returning again and again.
John Bartram collected Xanthorhiza simplicissima from the Carolina mountains sometime before 1776 and brought the plant back to his famous Philadelphia garden, which tells you two things: that yellowroot has been in cultivation for as long as this country has existed, and that people who know plants have always recognized something worth paying attention to here. The Cherokee had known the plant far longer, using the roots, sliced open to reveal a vivid, almost electric chrome yellow, as a dye, a bitter tonic, and a medicine for ailments from mouth sores to stomach complaints. The active compound is berberine, the same antimicrobial alkaloid found in goldenseal, and the roots produce berberine in striking quantity. Xanthorhiza is Greek for yellow root, and the name is no metaphor.
