The shrubs that furnish a garden. Small and medium shrubs are the versatile, human-scaled woody plants that fill borders, edge paths, and knit the taller structure to the ground, the layer most gardens rely on most.
Woodlanders has long led in offering citrus and citrus hybrids hardy well beyond the usual citrus belt, and the Keraji mandarin is a favorite of the group. A medium-sized evergreen tree with the usual fragrant white citrus flowers, Keraji follows them with what Tom McClendon, in Hardy Citrus for the Southeast, calls "small, yellow, flattened tangerines that have a sweet lemonade taste unlike any other citrus fruits." That flavor is the whole reason to grow the tree, and Keraji has proven quite hardy in Augusta, Georgia since 1997.
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.
Clinopodium georgianum is a low, aromatic shrublet of the mint family, prized for highly scented foliage and clouds of pinkish-lavender flowers in late summer and fall, when much of the garden is winding down. Georgia savory makes a fine edging or front-of-border plant for sunny or lightly shaded spots with good drainage, and unlike most of the tribe, this southern native will grow in heavier soils as well as sand.
Conradina canescens 'Gray Mound' is a silver-leaved selection of the false rosemary that grows wild on the deep, pine-fringed sands of the northern Gulf Coast, in Alabama, Mississippi, and the Florida panhandle, where the species once mingled with sea oats and longleaf pine. A member of the mint family, this aromatic shrub carries soft, needle-like foliage in a ghostly silver-gray, and from spring into early summer, sometimes again in the cool of fall, offers a flush of pale lavender to bluish, two-lipped flowers that native bees and butterflies work eagerly.
The limequat was born of catastrophe. After the twin freezes of 1894 and 1895 laid waste to Florida's groves, Walter T. Swingle of the United States Department of Agriculture set out to breed citrus that could shrug off a cold snap, and in 1909 he crossed the sharp little West Indian or Key lime (Citrus aurantifolia) with the round Marumi kumquat (Fortunella japonica). Named and introduced in 1913 alongside a sister seedling called Lakeland, the Eustis limequat stands among the first successful intergeneric citrus hybrids, living proof that two separate genera could be wedded and still bear generous fruit.
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.
Morella pumila is the dwarf waxmyrtle, a low, native evergreen that keeps everything gardeners love about the common wax myrtle, aromatic foliage, waxy berries, and a tough constitution, and shrinks it all to knee height. Native to the frequently burned pinelands of the southern United States, the plant is an adaptation to that fiery world, staying small and spreading slowly into dense patches and colonies by underground runners.
In Japan they call the shrub tobira, short for tobira no ki, the door tree, because the cut branches were hung in the doorway at Setsubun to turn back demons at the threshold of spring. The broken wood smells rank, which was rather the point: bad spirits, like most of us, would rather not walk through a bad smell. The genus name is kinder and more exact, pitta and sporos, pitch and seed, for the resin that coats the black seeds and glues them to whatever bird carries them off.
Polygala x dalmaisiana, the sweet pea shrub, is a fast-growing evergreen hybrid of two South African species (P. oppositifolia and P. myrtifolia), grown for a nearly year-round show of orchid-like flowers on an open, informal frame.
Nearly every rose in your garden that blooms more than once a year owes a debt to this one. 'Old Blush' is a China rose, bred in China for something close to a thousand years and known there as the monthly pink, and they are generally reckoned the first East Asian rose to reach Europe, recorded in Sweden by 1752 and offered in England as Parson's Pink China in 1793. They brought with them the one thing Western roses simply did not have: the habit of blooming again and again across the season rather than once and done. Crossed into the old European roses, that single trait rewrote the genus. On the Ile Bourbon they met an autumn damask and produced the Bourbons; in Charleston, just down the road, the rice planter John Champneys crossed them with a musk rose and produced the first Noisette, the only rose class born in the American South. Bourbons, Noisettes, hybrid perpetuals, and in time the hybrid teas all trace back through this unassuming pink shrub. 'Old Blush' could have retired on the legacy and instead just kept flowering. In the South they are very nearly everblooming, throwing clusters of soft semi-double pink that, in the China way, deepen rather than fade in the sun, blush going to rose as each flower ages. The canes are nearly thornless, the constitution famously tough; these are the roses you still find blooming alone at abandoned homesteads, having outlived the house and the gardener both. Grow them for the flowers. Know that you are also growing the root of the whole modern family.
Rosemary is a timeless classic in both the garden and the kitchen, an aromatic evergreen shrub of the sun-baked Mediterranean coast, so distinctive that botanists long kept rosemary in a genus apart, Rosmarinus officinalis, before recent study moved the herb into the sages as Salvia rosmarinus. The old genus name means dew of the sea, for the plant's love of bright, salt-swept coastal hillsides. Slender, needle-like, deep green leaves clothe the woody stems the year round, and soft blue flowers open along them from winter into spring.

The Sunquat began as an accident in a Beeville, Texas dooryard in the early 1940s, when a man named Leslie Cude noticed a seedling carrying fruit that looked like a small lemon and behaved like a kumquat. Walter Swingle, the great citrus authority of the day, took one look and guessed a cross of Meyer lemon and kumquat, which is where the name Lemonquat comes from and how it entered the collections as Citrus limon × Fortunella. The trouble is that the curators who have kept the tree at Riverside ever since have come to doubt him. The fruit, they think, points to a mandarin somewhere in the parentage rather than a lemon, which would make the plant a mandarinquat wearing the wrong label. Nobody has settled the question. The plant has gone out as Sunquat, Lemonquat, Lemondrop, and Marmaladequat, four names for one tree, each a different theory and not one of them proven. Asking a citrus to hold still long enough to be classified rather misunderstands the family.
Woodlanders has long been a leader in offering citrus and citrus hybrids hardy well beyond the usual citrus belt, and the 'Razzlequat' is one of the odder and hardier of the lot. The plant is a cross between the Australian desert lime, Eremocitrus glauca, a tough, drought- and cold-tolerant native of the arid Australian interior, and, most likely, the familiar 'Meyer' lemon. From the desert lime parent come thorny, wiry branches, small narrow gray-green leaves, and a hardiness and drought tolerance rare among citrus; from the lemon come size and flavor.
A cold-hardy citrus with a Woodlanders pedigree. Woodlanders has long led in offering citrus and citrus hybrids that stand outdoors beyond the usual citrus belt, and the calamandarin is one of the toughest. Likely a hybrid of a mandarin, Citrus reticulata, and a calamondin, the calamandarin blends easy-peeling, tangerine-like fruit with the cold tolerance that calamondin brings to the cross.
A seldom-seen species with old-world charm, Abelia chinensis is a deciduous shrub native to China and one of the foundational parents of the widely grown Abelia x grandiflora. Far less common in American gardens than its hybrid offspring, the true species offers its own quiet distinctions: larger foliage, a fuller habit, and a long summer season of bloom that makes it a thoughtful choice for collectors and pollinator gardeners alike.
Abeliophyllum is a genus of a single species, first described from Korea in 1919 and grown in Western gardens since the 1930s, when it earned an Award of Merit from the Royal Horticultural Society. It belongs to the olive family beside lilac and forsythia, and in the wild it clings on at only a handful of Korean sites, where it is now protected by law as an endangered plant. This is the white-flowered species itself, the parent of the better-known pink form.
Few plants announce themselves the way Cestrum nocturnum does, and never by daylight. Through the afternoon the shrub keeps to a quiet, almost ordinary green, the slender branches arching and half-climbing, the small tubular flowers furled and unremarkable. Then dusk arrives, the cream-green trumpets open, and the night-blooming jasmine releases a perfume so far-reaching that it carries across a whole garden on still, warm air.
Choisya is a small genus of aromatic evergreen shrubs from the southwestern United States and Mexico, kin to citrus in the rue family, and Choisya 'Aztec Pearl' is the garden world's favorite of the tribe. The hybrid, a cross between Choisya arizonica and Choisya ternata, was raised by Peter Moore at Longstock Park Nursery in England, and the selection has proved hardier, more heat tolerant, and altogether easier in the garden than either parent.
The rockroses bloom as if for a single day, and in a sense they do. Each papery flower of Cistus x purpureus lasts only from morning to evening before dropping, yet through late spring the shrub opens fresh bloom after fresh bloom, so the whole plant seems perpetually covered. The flowers are the draw: two to three inches wide, crushed-silk petals of pinky purple, each stamped at the base with a deep maroon blotch, a marking that earned the old garden name orchidspot rockrose. Rockroses are not roses, and are not related; the resemblance is only in the open, five-petalled face.
The Yuzuquat is a tri-generic hybrid, a curiosity even among unusual citrus. One parent is the yuzu, itself a cross of Citrus ichangensis and Citrus reticulata; the other is the 'Nagami' kumquat, Fortunella margarita. From that three-way pedigree comes an attractive evergreen citrus that bears sour, juicy, lemon-like fruits about the size of a chicken egg.
