Phlox carolina 'Kim' is among the best of the Carolina phloxes, a selection found by the plantswoman Jan Midgley in Alabama and grown ever since for good health and honest flower power. From a low, tidy clump of narrow, almost lime-green leaves rise sturdy stems eighteen to twenty-four inches tall, each carrying an open, airy cluster of pale to bright pink flowers, five petals apiece, hovering just above the foliage from late spring into early summer. Where the border phloxes so often finish the season spotted and tired, 'Kim' holds clean, fresh foliage from spring straight through fall.
Symphyotrichum oblongifolium, the aromatic aster, saves the best of the season for last. Long after most perennials have folded, this tough native throws up a low, spreading mound of stiff, well-branched stems and buries the whole clump under small violet-blue daisies, each lit with a bright gold eye, from early fall well into November. The show arrives just as the garden goes quiet, and the flowers hum with the last bees and butterflies of the year.
Amorpha fruticosa, the false indigo bush, is the largest and most widespread of the native false indigos, a fast, open, deciduous shrub that carries long spires of tiny deep blue-purple flowers, each lit with a single vivid orange anther, at the branch tips in late spring and early summer. From a suckering base rise arching stems six to twelve feet tall, clothed in soft, ferny, pinnate leaves that give off a clean, resinous scent when crushed. In full bloom the whole shrub seems to smoke with color, and the flower spikes hum with bees.

Jasminum x stephanense, the Stephan jasmine, is the rare pink-flowered hybrid of the group, a cross between the red jasmine, Jasminum beesianum, and the poet's jasmine, Jasminum officinale. The vigorous, semi-evergreen scrambling vine carries small, soft pink, fragrant flowers over slender stems clothed in fine pinnate leaves, combining the pink of one parent with the hardiness and perfume of the other.
Jasminum officinale var. grandiflorum, the Spanish or Royal jasmine, is the large-flowered, intensely fragrant jasmine of perfume and tradition, a semi-evergreen twining vine that opens clusters of pure white, star-shaped flowers whose scent is among the most prized in the plant world. Larger-flowered and more tender than the common poet's jasmine, this is the plant behind jasmine absolute, the costly essence at the heart of classic perfumery.

Salvia 'Indigo Spires' is a big, free-flowering hybrid sage grown for the long, tapering wands of violet-blue bloom it throws from early summer straight through to frost. Each spike packs small, rich violet flowers tightly in whorls above dark, near-black calyces, and the spikes lengthen and curve as the season goes, so a settled clump reads as a haze of deep blue-purple for months on end. Few perennials give so much color for so long a run.
Clethra alnifolia, the summersweet or sweet pepperbush, is a deciduous native of the eastern United States, at home along pond edges, in damp woods, and at the margins of coastal swamps from Maine to Florida. The species spreads gently by suckers into colonies of upright stems, and earns the name sweet pepperbush from the small, peppercorn-like seed capsules that follow the flowers and hang on through winter. For all that, the summer flowers are the reason to grow them: erect bottlebrush spikes, intensely honey-scented, that open over many weeks in the heat of July and August when little else in the shrub border is in bloom.
The gardenia needs no introduction in the South; the scent alone has been stopping people in driveways for generations. What 'Chuck Hayes' adds to that old story is nerve in the cold. The line traces back to the late 1970s and a Virginia Beach nurseryman named Charlie Hayes, who noticed a single-flowered gardenia that had come through a brutal freeze unbothered. He crossed that survivor with a double-flowered plant and handed the seedlings to Dan Milbocker, a horticulturist at the Hampton Roads research station, who grew them out, picked the toughest, and eventually released the plant under Hayes's name. The result is a fully double, classically fragrant gardenia that behaves as a far more delicate shrub has no right to.
Oleander, Nerium oleander, is the great sun-loving evergreen of the Mediterranean, grown since antiquity for a long summer of bloom, with dark green, leathery, lance-shaped leaves in whorls of three along long, sparingly branched stems. 'Hardy Pink' is one of the cold-tougher selections, carrying showy, lightly fragrant clusters of clear rose-pink flowers from late spring well into fall.
Some plants are loved for how they look. Calycanthus floridus is loved for how they smell, which is a different and older kind of attachment. The flowers are strange and handsome in their own right, an inch or two across, dark maroon going toward burgundy, built from many narrow strap-like segments with no clear line between petal and sepal, somewhere between a small magnolia and something from the bottom of the sea. But the reason this shrub has been passed down through Southern gardens for three centuries is what happens when the flowers open on a warm day: a deep fruit-bowl perfume, strawberry and pineapple and ripe banana, that drifts well beyond the plant.
Calycanthus floridus 'Athens', also circulated under the name 'Katherine', is a yellow-flowered selection of the Eastern sweetshrub, a deciduous native of the Southeastern woodlands long grown for fragrance, adaptability, and strange, many-tepaled flowers. Where the wild plant blooms a deep maroon, 'Athens' opens soft, buttery yellow, an unexpected and elegant turn on a familiar shrub.
Here is a salvia that wants what salvias are not supposed to want. Most of the genus comes from sunbaked Mediterranean hillsides, dry Mexican mountains, and dusty California chaparral, so that the very word Salvia is shorthand for full sun, gravelly soil, and a watering regime closer to neglect than care. Salvia koyamae, endemic to the cool wooded slopes of Honshu in Japan, breaks every rule, asking instead for shade, moist humus-rich woodland duff, and the cool morning light that filters through a deciduous canopy. This is, in short, the salvia to grow where hostas would otherwise go.
This is the tea plant. Not a tea plant but the tea plant. Every cup of green tea, black tea, white tea, oolong, and pu-erh on Earth comes from a single species, Camellia sinensis. The differences in flavor and color come from the timing of the harvest and the way the leaves are handled afterward: green tea from the youngest leaves, briefly steamed; white tea from the unopened buds; black tea from fully oxidized older leaves; oolong from partial oxidation. One plant, many fates.

Three things to know about this camellia. First, the tea-oil camellia is the most economically important non-tea member of the genus. China has cultivated Camellia oleifera for over two thousand three hundred years for the oil pressed from the seeds, a light, sweetish, monounsaturated cooking oil chemically close to olive oil (around eighty percent oleic acid in both), used for cooking, traditional cosmetics, hair tonics, and the historic rust-proofing of Japanese woodworking tools and chef's knives. Tea oil sits with olive, palm, and coconut among the four major woody oil crops on Earth. This is a working tree.
'Cherry Queen' is a North Carolina-bred salvia from one of the most important salvia hybridizers America has produced. The cross is a deliberate one, between Salvia greggii, the autumn sage of the Texas and Mexican borderlands, prized for drought tolerance and a six-month bloom, and Salvia blepharophylla, a Mexican species whose name, eyelash-leaved sage, comes from the tiny fringe of hairs at the edge of each leaf (Greek blepharon, eyelash, and phylla, leaves). Blepharophylla carries the most saturated, signal-bright red flower in the whole genus, but the plant spreads by stolons in ways most gardeners do not want and resents cold winters, while greggii brings the bones and the durability. The breeder who put the two together was Dr. Richard "Rich" Dufresne of Candor, North Carolina, an organic chemist who became, more or less by accident, the leading American breeder of woody salvias for the eastern climate. Dufresne died in December 2018, leaving a body of work that includes 'Cherry Chief', 'Maraschino', and this selection, which Plant Delights Nursery called the most brilliant red they had ever seen on any hardy salvia.
A small rose with a long story. 'Magic Dragon' is a 1969 introduction by Ralph S. Moore (1907 to 2009), the legendary Father of Miniature Roses, who bred more than three hundred cultivars from a small nursery in Visalia, California across nearly seven decades. Moore all but invented the climbing miniature category single-handedly, crossing tiny old varieties like Rouletti with full-sized climbers and selecting the offspring that kept the small leaves and flowers but stretched into climbing wood.
Salvia 'Phyllis Fancy' is a vigorous, large hybrid sage with a good pedigree, found as a chance seedling at the University of California, Santa Cruz Arboretum and named for a longtime volunteer there. The parentage is thought to involve Salvia leucantha, the Mexican bush sage, and possibly Salvia chiapensis, though the cross has never been confirmed.
A Victorian-era English selection of one of the great trees of North America. The species, Thuja plicata, the western red cedar, is the dominant conifer of the Pacific Northwest coastal rainforest, the tree that towers 150 to 200 feet above the forest floor in old-growth stands of British Columbia, Washington, Oregon, and northern California, with individual specimens documented at over a thousand years old. To the Coast Salish, Haida, Tlingit, Kwakwaka'wakw, and other Pacific Northwest Indigenous peoples, western red cedar is the Tree of Life: the wood used for longhouses, dugout canoes, totem poles, and ceremonial regalia; the bark woven into baskets, mats, capes, and dress; the whole tree a structural and cultural foundation for thousands of years. That natural rot-resistance comes from the same volatile terpenoids that give the crushed foliage a sweet, cedary fragrance, the smell of the Pacific Northwest forest itself.
A native plum with a longer human history than any other fruit in North America. Prunus angustifolia, the Chickasaw plum, also called Cherokee plum, sand plum, sandhill plum, or Florida sand plum depending on the part of the range you are standing in, was actively cultivated by Indigenous peoples across the southeastern and central United States long before European contact. The Chickasaw, Cherokee, and several other nations carried the species in their orchards and food gardens, dried the fruit for winter storage, and almost certainly moved the plant eastward through pre-Columbian trade networks from what botanists now believe to be the species' true origin further west. The species was so deeply associated with Indigenous cultivation by the time European naturalists arrived that the binomial angustifolia, narrow leaf, eventually displaced earlier names like P. chicasa in formal taxonomy, though the common names kept the tribal attribution. Kansas made the plant its official state fruit in 2022. Few American native fruits carry their human history this visibly.

The hardiest yellow oleander in cultivation, and one of the very few oleanders that come in yellow at all. Of the four hundred and more named cultivars of Nerium oleander, the genus runs naturally to white, pink, and red; yellow is the aberration, and a fully double yellow rarer still. 'Double Yellow' is the old French selection that fixed the color.
