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.
Prunus japonica, the Japanese bush cherry or Japanese almond-cherry, is a compact deciduous shrub grown for an early flood of delicate pink-to-white bloom. Wiry branches carry dense clusters of five-petaled flowers just as the leaves appear, wrapping the low, rounded frame in soft color in early to mid spring.
Pyracomeles vilmorinii is the sort of plant collectors trade knowing looks over, a small, fine-textured evergreen so uncommon that most gardeners have never met one. The little leaves are cut into narrow, fern-like divisions along arching, thornless branches, and in spring flat clusters of small white flowers give way by autumn to a scatter of coral-red fruits. The overall effect is airy and delicate, unusual in an evergreen shrub.
Rhododendron atlanticum, the coastal or dwarf azalea, is a low, colony-forming native of the open pine woods and sandy flatwoods of the mid-Atlantic and Carolina coastal plain. Unlike the tall wild azaleas of the mountains, this species stays close to the ground, often no higher than the knee, and spreads by underground runners, or stolons, into broad, drifting colonies. The bluish, glaucous foliage is a hallmark, cool and sea-gray, and the species name atlanticum simply marks the plant's home along the Atlantic seaboard. The genus name Rhododendron means rose tree in Greek; azalea comes from azaleos, meaning dry, a fitting root for a shrub of sandy, well-drained ground.
Chapman's rhododendron is a compact evergreen shrub of six to eight feet, carrying small, thick, distinctly rounded leaves in a light green, with margins that roll under slightly at the edge. In late spring the plant opens clusters of rose-pink flowers, funnel-shaped and freely borne, and the effect on a well-grown specimen is generous rather than sparse. Set beside the closely related Rhododendron minus, this plant reads lighter and rounder in the leaf, and most authorities now treat the two as one species, filing this one as Rhododendron minus var. chapmanii. We keep the name under which gardeners and native-plant people know the plant.
'Chapmanii Wonder' is an uncommon and rewarding evergreen rhododendron, the offspring of an inspired cross made by a Japanese breeder between two very different parents. From the endangered Florida native Chapman's rhododendron, Rhododendron chapmanii, the plant inherits broadleaf evergreen foliage and Deep South heat tolerance; from the hardy white-flowered form of Rhododendron dauricum, a species of northeastern Asia, the plant takes cold hardiness and early bloom. The species name dauricum points to Dauria, the region of southeastern Siberia where that parent grows wild, while chapmanii honors Alvan Wentworth Chapman, the nineteenth-century botanist of the Southern flora.
'Balsaminaeflorum' is a dwarf evergreen Satsuki azalea, an old Japanese cultivar of Rhododendron indicum grown for flowers that look less like azaleas than like tiny roses. Each bloom is fully double, packed with forty or more petals and carrying neither pistil nor stamens, so the flower is all soft, ruffled color. The cultivar name means balsam-flowered, a nod to the double blooms of the garden balsam, while indicum, meaning of India, is an old misnomer for a plant that is in fact Japanese.
A three-hundred-year-old Japanese garden azalea that does not look quite like a rhododendron, does not look quite like an azalea, and does not really look like anything else. The leaves are narrow green ribbons, three to five millimeters wide and a couple of inches long, closer to willow or fine grass than to the broad rounded foliage of an ordinary tsutsuji. The flowers, opening in late April and May, follow the same grammar: deeply divided into long strap-like petals in lilac-pink to lavender-rose, tangled and knotted at first, then unfurling slowly into a shape that reads, depending on the eye, as a crane fly, a spider, or a piece of decorative garnish. Wabi-sabi made evergreen.
'Koromo Shikibu' is the spider azalea, and there is nothing else in the genus quite like the flower. Instead of the usual funnel, each bloom splits into narrow, strap-like petals that spread apart like the legs of a starfish or a spider, lavender to purplish-pink, spotted darker at the base, and carried in such profusion in spring that the whole shrub seems to shimmer. Once seen, the flower is not forgotten.
Jetbead is an old-fashioned, exceptionally tough deciduous shrub of the rose family, forming an open, multi-stemmed mound roughly three to six feet tall and four to nine feet wide on arching gray-brown stems. The opposite, sharply toothed leaves break very early in spring, and four-petaled white flowers about two inches across open at the shoot tips in May and June. Clusters of three or four glossy black drupes follow in fall and hang on well into winter, the shining beads that give jetbead the common name.
Fragrant sumac is a versatile deciduous shrub native across much of the eastern and central United States, where the plant threads scattered woodlands, rocky slopes, and open banks. The trifoliate leaves, often mistaken at a glance for poison oak, are entirely harmless, and a crushed leaf releases the clean, lemony-resinous scent that gives the plant every one of the common names, from fragrant sumac to skunkbush, depending on the nose. The genus name Rhus is the old Greek and Latin word for the sumacs, and the epithet aromatica names the scent directly.

Rubus coronarius, often called the Easter Rose, is one of those plants that gently refuses categorization. Botanically the species sits squarely among the brambles, a blackberry relative, yet in bloom the shrub bears no resemblance to anything prickly or wild. In place of the usual bramble flower comes a flush of large, fully double white blooms that read far more like heirloom roses than raspberries, each one softly luminous and timed, in the mildest springs, to open around Easter, from which the common name follows.
Ruscus aculeatus, Butcher's Broom, is a low evergreen shrub of the asparagus family, native to the woodlands of southern Europe, the Mediterranean, and the Middle East, and reaching north into the milder parts of the British Isles. What look like glossy, spine-tipped leaves are not leaves at all but flattened stems called cladodes, which take over the work of photosynthesis while the true leaves are reduced to tiny scales. The generic name comes from the Latin ruscum, the old word for a butcher's broom, and the epithet aculeatus means prickled, for the sharp point that tips each cladode.
The willows gave the world its first painkiller. Willow bark, steeped by Greek and Native American healers alike for fever and ache, carries salicin, the compound nineteenth-century chemists refined into salicylic acid and, in time, aspirin, which still wears the genus name buried in the chemistry. This particular willow comes by a quieter trade. Salix koriyanagi is the Korean basket willow, the name meaning just that, long grown across Korea, Japan, and China for slender rods woven into baskets and furniture by hands that wanted something straight, supple, and strong.
Salvia darcyi, the Galeana sage, is a bold Mexican sage grown for one of the purest scarlets in the whole tribe of salvias, a color that reads across a garden and pulls hummingbirds from a distance. Through the heat of summer and well into fall, upright spikes of large, bright orange-red flowers rise above a mound of soft, gray-green, heart-shaped leaves that release a clean minty scent when brushed. Few tender salvias give so long or so vivid a show.
'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 guaranitica is the blue that gardeners keep looking for and rarely find. From midsummer through to frost the plant sends up long spikes of tubular flowers in a deep, saturated blue, each one held in a calyx of darker purple-blue so the whole spike reads richer than the petals alone would manage. The leaves are heart-shaped, soft green, and release a clean anise scent when brushed, which is where the common name comes from. Hummingbirds find this sage and then keep the address.
This plant is a botanical time machine. Sarcandra glabra belongs to the Chloranthaceae, a flowering-plant family with only four surviving genera worldwide and a fossil record reaching back into the Early Cretaceous, more than a hundred million years ago. Pollen and floral fossils of the Chloranthaceae are among the earliest evidence of flowering plants anywhere on Earth, and the family was already abundant when the dinosaurs were only in their middle age. Today Sarcandra is one of just four genera left from a lineage that once spread across what is now Portugal, Spain, and eastern North America, and most of that Cretaceous diversity is gone. The little plant in the garden is a quiet survivor of a family that mostly did not make it.
Sarcococca confusa, sweet box, is one of the great winter-fragrance shrubs, a compact evergreen of the boxwood family grown for a perfume out of all proportion to the flowers that carry it. In the depths of winter the small, tassel-like, creamy white flowers open along the stems, tucked among the leaves and easy to miss by eye, but their sweet, honeyed scent carries yards on a mild day and stops passersby in their tracks.
Sarcococca orientalis is a fragrant, uncommon sweet box from China, a compact evergreen of the boxwood family grown, like its kin, for a winter perfume far larger than the flowers that carry it. In late winter small white flowers open along the stems, modest to the eye but richly and sweetly scented, filling a still, mild day with fragrance and giving the shade garden a lift when little else stirs.
Sarcococca ruscifolia, the fragrant sweet box, is an evergreen shrub of the boxwood family, native to China and East Asia, grown for a winter perfume that belies the tiny flowers that carry it. In late winter and early spring the small, creamy white flowers open along the glossy stems, easy to overlook by eye but powerfully sweet on the air, and unlike the black-fruited sweet boxes, this species follows the flowers with glowing red berries.
