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.
Two things the common names get wrong: it is not Chinese, and it is not a maple. Abutilon pictum comes from the warm river country of southern Brazil and its neighbors, Argentina, Paraguay, and Uruguay, and the maple lives only in the leaves, which are lobed and toothed enough to have fooled people into "flowering maple." It belongs instead to the mallow family, in good company with hibiscus, hollyhock, okra, and cotton, and it carries that resemblance in every five-petaled bloom.
Call it a flowering maple if you like, but there is not a drop of maple in it. Abutilon pictum belongs to the mallow family, alongside hibiscus, hollyhock, okra, and cotton, and only the lobed, maple-shaped leaves account for the nickname. What the leaves of 'Souvenir de Bonn' actually do is carry a wide, irregular margin of cream around their green, a variegation bold enough to earn the plant its place on looks alone. The flowers settle the matter. All season they dangle from the branches like small paper lanterns, apricot to salmon, each bell veined through with crimson, swinging on thin stalks where the hummingbirds find them. 'Souvenir de Bonn' is among the oldest abutilons still in gardens, a parlor plant out of the conservatory age, when a variegated flowering maple was the sort of thing one kept in a bright room through winter and carried out to the terrace each summer. The species hails from Brazil; the cultivar name is a keepsake of Bonn, a souvenir that outlasted whoever first carried it home. They are tender, frost being their one real enemy, and in our climate they may sail through a mild winter outdoors or die to the ground and return from the root. Either way they earn their keep, blooming spring to frost and beyond, asking only for sun, rich soil, and water enough to keep the show going. Set them where you pass close, on a patio or against a warm wall, where the lanterns can be read at eye level.
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.
A rare, semi-evergreen shrub, Baccharis dioica resembles the common groundsel bush, Baccharis halimifolia, but is quite distinct. In 1979, just before Hurricane Frederic did tremendous damage to the Mobile, Alabama area, we found this plant growing behind the dunes on Dauphin Island.
Callicarpa acuminata, the black beautyberry, is the Mexican cousin of the familiar American beautyberry, a deciduous shrub of arching branches that, in fall, lines the stems with clusters of small, shiny berries in glossy black rather than the usual purple. The dark fruit is a quiet, sophisticated turn on the beautyberry idea, set off by the green leaves and lingering into the cool months.
The white-fruited form of the Asian beautyberry, Callicarpa dichotoma 'Albifructus' is a quiet pleasure of the late-summer border: instead of the usual magenta, the arching stems hang with luminous, ivory-white berries in elegant clusters, cool and refined where the purple kinds are bold. Native to eastern Asia, in Korea, China, and Japan, the white beautyberry is smaller and more graceful than the American species, and all the more striking for the restraint.
Camellia euryoides offers a quiet counterpoint to the camellias most familiar to American gardeners. Where Camellia japonica and Camellia sasanqua have long defined the genus in cultivation here, those two represent only a sliver of a far broader Asian lineage. C. euryoides, a shrub or small tree of the subtropical forests of Fujian, Guangdong, and Jiangxi, belongs to that richer world of species camellias: subtler, finer in texture, and made for gardeners curious about the genus beyond its showiest forms.
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.
'Desi Arnez' (Clinopodium georgianum hybrid) turned up as a chance seedling in the garden of Robert Mackintosh, a cross of uncertain parentage that Woodlanders judged worth keeping and worth introducing. The likeliest account is a quiet romance between Georgia savory (Clinopodium georgianum) and a neighboring false rosemary (Conradina), two southeastern natives that seldom bother to cross the line between their genera. Botanists who keep their Latin tidy now file the result under the bigeneric name ×Clinadina, which is roughly how the field admits it never saw the match coming.
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 genus name comes from the Greek dichroos, meaning "two-colored," and Dichroa versicolor presses the idea further: bloom color shifts with soil chemistry much the way a hydrangea does, swinging from deep cobalt to soft mauve depending on how much aluminum a plant can draw up. The species epithet versicolor only doubles down on the point, promising a shrub that refuses to settle on a single shade.
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.
We are identifying this little-known fig as Ficus heterophylla thanks to Tony Avent of Plant Delights, who was most likely the source of the cuttings we originally started with. The species name means different leaves, and the plant lives up to the promise: juvenile foliage may be lobed and wandering in outline, while the mature leaves settle into dark green, pointed, slightly heart-shaped blades carried on handsome red petioles. A faint sweetness hangs about the shrub, and the long, almost vine-like branches lend the whole plant a loose, scrambling grace.
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.
Heimia salicifolia is an airy, fine-textured shrub that carries a surprising amount of history in a modest frame. Slender willow-like leaves clothe the arching stems, and from midsummer into fall small, bright yellow, five-petaled flowers open in the leaf axils all along the branches, each followed by a little dry seed capsule. The overall effect is light and gauzy, a soft yellow haze rather than a bold splash, and the plant grows fast and multi-branched into a rounded, four-to-eight-foot mound.
From the warm lower slopes of the Himalayas, where they scramble through scrub from India and Nepal on into Bhutan, comes one of the more theatrical shrubs you can grow. The genus carries the name of Johan Theodor Holmskiold, an eighteenth-century Danish botanist, while sanguinea nods at the blood-red flush the flowers take on with age. For years they sat in Verbenaceae. Botanists have since moved them into Lamiaceae, the mint family, which makes them distant kin to salvia, rosemary, and teak. You would never guess as much to look at them.
'Preziosa' is a small, jewel-like hydrangea with a tangled pedigree and an unusual gift. Raised in Germany from the nursery tradition of Georg Arends and introduced around 1961, the shrub is a hybrid of Hydrangea serrata and Hydrangea macrophylla, and catalogs list the plant under all three names depending on which parent they favor. Whatever the label, 'Preziosa' behaves like a compact mophead, three to four feet high and wide, built for a smaller garden.
Hypericum nudiflorum is the early riser among the St. John's Worts, a slender, upright shrub that opens golden flowers as early as May, often a full month ahead of relatives. The blooms carry the many-stamened brush typical of the clan, set against broad, light green, oval leaves that give the plant a softer, leafier look than the needle-leaved species.
