Smooth sumac is a bold, colony-forming native shrub of the eastern and central United States, in time reaching the scale of a small tree, and one of the finest plants going for a hot, dry, sunny site where little else will thrive. The long, pinnately compound leaves give an almost tropical texture through summer, and the plant spreads by root suckers into broad, picturesque colonies, or can be held to a single tree-like specimen where the suckers are controlled.

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.
Rudbeckia fulgida var. fulgida is the true orange coneflower, the wild species that stands behind the famous 'Goldsturm', quieter, finer, and later to bloom than that celebrated garden child. From a low clump of dark, roughly hairy leaves rise branching stems two to three feet tall, each ending in a small golden daisy about two inches across, the deep yellow rays set around a low dome of brown-black. Where many of the black-eyed Susans have blazed and faded by August, the orange coneflower is only getting started, carrying many small flowers from late summer well into October.
Staghorn sumac is a bold native shrub or small tree of the northeastern United States and Canada, growing fifteen to thirty feet on stout, forking stems clothed in fine velvety hairs, the texture and antler-like branching that give the plant the name. The big, pinnate leaves are bright green through summer and turn a spectacular blend of yellow, orange, and red in fall, one of the great autumn shrubs of the eastern flora.

Yaupon holly is a small-leaved evergreen shrub or small tree of the southeastern United States, native from coastal Virginia south to Texas. Adaptable to a fault, salt tolerant, drought tolerant, and willing in sun or shade, yaupon takes shearing as gracefully as any boxwood, which has made the species a Southern mainstay for hedges, topiary, and clipped evergreen structure. The tiny white spring flowers are easy to miss, but the bees do not miss them, and on female plants they give way to a heavy crop of small, translucent berries that hang on well into winter.

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.
Few plants carry their history as plainly as Danae racemosa. The name reaches back to Greek myth, to Danae, daughter of the king of Argos, and the foliage carries a heavier classical freight than almost anything else you can grow in shade: Roman poet laureates are said to have worn the sprays as their wreath, and Alexander the Great may have taken his victory crowns from the same hills where he was fighting. Hence the two common names that have followed the plant for centuries, poet's laurel and Alexandrian laurel. Danae is, for the record, no true laurel at all.
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.
Hamamelis virginiana does everything backwards, and that is the entire appeal. When the rest of the woods has shut down for the year, when the leaves are gone and nothing else is in flower, witch hazel chooses that exact moment to bloom: spidery yellow flowers, all thin crimped strap-like petals, scattered along the bare branches through late fall and into the cold. They carry a faint sweet scent on a mild day and they wait, patiently, for whatever gnat or late fly is still working, because almost nothing else is. This is the shrub that flowers when flowering makes no sense, and is all the more loved for the defiance.
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.
A small crested iris with the carriage of an orchid and a quietly extraordinary biography. Iris japonica was named by Carl Peter Thunberg in 1794. Thunberg was a protege of Linnaeus and one of the only Western botanists allowed into Japan during the country's closed period, from 1775 to 1778, so much of what he brought back is, in a real sense, the first documented record of Japanese flora in Western science. The species had already reached Europe two years earlier, carried out of China by Thomas Evans of the East India Company in 1792. By the 1820s Pierre-Joseph Redoute, the same artist whose rose paintings turn up on every aunt's tea tray, was painting the plant under the older name Iris fimbriata in his Choix des plus belles Fleurs. A treasure of cultivated gardens for more than two centuries.
A spring-blooming native of the eastern woodlands, found from Ontario and Quebec south through the Appalachians and as far west as Minnesota and Oklahoma, growing on rich deciduous forest floors, along streambanks, and at the bases of sandstone canyons. Polemonium reptans is one of those native plants that rewards close attention. The leaves are pinnately compound, with seven to twenty-one paired leaflets running up each stem like the rungs of a ladder, the source of the common name, which gestures all the way back to the biblical Jacob and his dream of a stairway to heaven. The genus name is older still: Polemonium honors King Polemon of Pontus, an ancient Greek ruler with a side interest in herbalism.

A dwarf form of one of Japan's legendary Five Sacred Trees of Kiso, the goboku no kinbatsu, a select group of conifers protected by feudal law for centuries, reserved for imperial residences and temple construction, where commoners caught poaching the wood faced execution. The species, Thujopsis dolabrata, is endemic to Japan and known there as asunaro, a name that translates beautifully and a little wistfully as tomorrow it will become hinoki, a nod to the tree's resemblance to the more revered hinoki cypress, forever almost but not quite the more famous tree. Thujopsis is the sole species in the entire genus.
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.
There is a book about Aucuba japonica called A Virgin for Eighty Years, which sounds like a romance novel and is, instead, one of the strangest stories in horticulture. The species arrived in England in 1783 as a single female plant. Aucuba is dioecious, male and female flowers on separate plants, so for the next eighty years every aucuba in English gardens was a clone of that one original female. Gardeners knew the plant was meant to bear bright red berries, since reports came back from Japan, but Japan had closed its borders, no male could be had, and they simply waited.
'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.
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.
The genus name says it: Callicarpa, from the Greek kallos, beauty, and karpos, fruit, beautiful fruit, a genus named for exactly what it does. Callicarpa americana, the American beautyberry, is the southeastern native that gives the genus a calling card. From late August into November, the plant sets dense clusters of small drupes in a luminous magenta-purple, a color that registers as almost unreal in the late-summer landscape, somewhere between fuchsia and amethyst, with no real precedent among native fruits. The berries gather in tight whorls around the stem at every leaf node, all the way down the arching branches, so that a mature shrub in October looks less like a shrub bearing fruit than a ribbon of purple glass beads strung along the branches.

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.
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.
