The garden's backbone: flowering trees, native and rare shrubs, and evergreens that hold their shape through every season. Many are Southeastern natives; others are quiet collector's plants you won't find at a big-box nursery, chosen for resilience and lasting, year-round interest.
Itea virginica, the Virginia sweetspire, is a native shrub of eastern wetlands, familiar in gardens for fragrant white flower spikes and fiery fall color. 'Shirley's Compact,' sometimes called Shirley's Midget, takes the species to an extreme: a true miniature, a dense little bun of a plant with tiny, twisted, inch-long leaves, growing so slowly that a ten-year-old clump may stand only a foot or a foot and a half tall while spreading two or three feet wide.
Juglans nigra, the eastern black walnut, is one of the great trees of eastern North America, a towering, long-lived hardwood native from the Appalachians and Midwest to the Mississippi Valley, most at home in deep, rich, moist but well-drained soils along river bottoms and fertile uplands. Large pinnate leaves cast a broad, airy shade in summer, leaf out late in spring, and drop early in fall to a soft gold, making way for the tree's most famous gift, the crop of hard-shelled nuts.

Spicebush is the shrub that tells you the ground is good. Early land surveyors in the eastern states used Lindera benzoin as an indicator of rich agricultural soil, and the rule holds in the garden: where spicebush thrives, most things will. The plant is a common understory shrub of moist, rich woods from Ontario to Florida and west to Texas, growing six to twelve feet in a loose rounded mass, often colonial from root sprouts, and every part smells of citrus and pepper when bruised.
This quietly handsome evergreen has grown well for years in the Woodlanders garden here in Aiken, South Carolina, holding a place in semi-shade where many broadleaf evergreens sulk. The spicebush earns a spot on foliage alone: glossy, leathery leaves, roughly heart-shaped and about three inches across, each marked by three bold veins, with new growth flushing a soft bronze before deepening to green.

In the dead of winter, when the garden asks for little and gives less, Lonicera × purpusii answers with perfume. This winter honeysuckle is a hybrid of two Chinese species, Lonicera fragrantissima and Lonicera standishii, and carries the best of both: small, creamy-white, tubular flowers that open along the bare stems from late winter into early spring, throwing a clean, lemon-sweet fragrance that carries yards on a mild day.
The Lauraceae is an underappreciated family. Its members include cinnamon, camphor, bay laurel, and the avocado, which gives you some sense of the range of things the family has contributed to human civilization. Machilus thunbergii is another member in good standing, though these trees arrive in the Western garden with considerably less fanfare than their relatives. In East Asia they are well known: a coastal evergreen tree native to Japan, Korea, Taiwan, China, and Vietnam, valued for timber, planted as a street tree, and the source of makko, a powder derived from the bark and used for centuries to bind incense and, in a more practical application, to repel mosquitoes. The bark also has a history in traditional medicine. Here, in other words, is a tree that has been useful to people for a very long time, which is not a bad thing for a plant to be.
Magnolia virginiana, the sweetbay magnolia, has long been a tree of distinction in the American landscape, ranging from the cool wetlands of Massachusetts to the Gulf Coast. Across that span the species wears two very different guises. In the northern states the sweetbay is a smaller, often shrubby tree that drops its leaves in winter; in the Deep South the species reaches fullest expression as Magnolia virginiana var. australis, the evergreen southern sweetbay, a large and enduring tree of great grace.
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.
Myrcianthes fragrans is a member of the myrtle family native to the hammocks and coastal scrub of Florida and the Caribbean, the same botanical neighborhood as guava and allspice, which says something about the family character and the quality of the fragrance involved. Crush a leaf and the scent is immediate and specific: nutmeg with a citrus edge, clean and resinous in a way that makes the plant worth encountering even out of flower. The tiny, deep green leaves hold the aromatic oils responsible, and keep that quality year-round.
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.
Black gum is one of the longest-lived hardwoods in eastern North America; individual trees have been aged past six hundred and fifty years, standing quietly in swamp margins and rocky uplands while everything human around them came and went. The names alone are a small history lesson. Nyssa was a water nymph of Greek myth, sylvatica means of the woods, so the botanical name reads as water nymph of the forest; tupelo comes from the Creek ito and opilwa, tree and swamp; and the old northern name pepperidge is the one a Connecticut baker borrowed for her farm and her bread company. Curiously, no part of the tree is gummy at all. What black gum does own is the autumn. They are among the first trees to turn and among the fiercest, the glossy summer leaves igniting into scarlet, orange, and deep wine-purple weeks before the rest of the woods has given the season a thought, an early flare that signals birds to the ripening blue fruit. The wood is so cross-grained it is nearly impossible to split, which sent it into tool handles, chopping bowls, and, where trunks went hollow with age, into bee gums, the log hives that made gum a synonym for beehive across Appalachia. Black gum is notoriously hard to move at any size, which is exactly why you so rarely see a big one for sale, and exactly why you should start one small, now, and let them outlive you.

A true olive for the shade, Olea yunnanensis is the sort of plant that rewards the gardener who reads labels twice. The genus is the olive genus, kin to the ancient Mediterranean fruit tree and to the sweet olives and privets of the same family, yet this species hails from the mountains of Yunnan in southwestern China rather than the sun-baked hills of the Old World. The narrow, leathery, dark green leaves carry an unmistakable Osmanthus cast, glossy above and paler beneath, and build into a dense, rounded evergreen canopy that holds the year.
Osmanthus armatus, a rare gem from the evergreen forests of western China, brings both elegance and resilience to the garden. This large, multi-branched shrub is known for thick, lustrous, dark green leaves adorned with prominent marginal and terminal spines, reminiscent of holly.
'Variegatus' brings light to the false holly. The spiny, holly-like evergreen leaves are edged in clean creamy white against a dark green center, so the whole shrub reads as a soft glow at a distance and a crisp, formal pattern up close. The variegation lifts a shaded corner the year round, a quiet luminance that the plain green species cannot offer.
Persea borbonia, the redbay, is a handsome broadleaf evergreen native to the southeastern United States, ranging from coastal Virginia through Florida and west along the Gulf. A member of the laurel family and a close relative of the avocado, the redbay carries the same aromatic oils, and the glossy leaves have long been used in the southern kitchen much as bay laurel (Laurus nobilis) is, to season soups, stews, and gumbo.
Almost everything about Pinus glabra argues against their being a pine at all. The bark is smooth and gray, close-grained, so like the bark of an oak or hickory that people walk straight past a mature one without taking the tree for a conifer; it is the single most reliable way to know the tree. The needles are soft, short, and paired, a cool dark green, worn in a dense rounded crown rather than the open candelabra of their relatives. And most usefully, they tolerate shade. Where nearly every other southern pine demands full sun and open, burned ground, spruce pine settles happily into the wooded margins just above the bottomlands, growing in the understory beneath oaks, beech, and magnolia. They were named by Thomas Walter, the English-born botanist of the Santee whose Flora Caroliniana appeared in London in 1788, the year before he died; the epithet glabra, meaning smooth and hairless, marks those glabrous young twigs. Even the timber keeps its own counsel, drying at so different a rate from other southern pines that mills cannot season it in the same batch. This is a pine for the places pines aren't supposed to go: the shaded corner, the woodland edge, the spot where you wanted evergreen structure and assumed you couldn't have it. Once you can recognize one, you start wanting them everywhere the light runs thin.
Before the South was farms and pavement it was, in great part, longleaf: an open, sunlit forest of widely spaced pines over a ground layer so rich a single square yard could hold dozens of species, the whole thing held together by fire. They ran across tens of millions of acres of the coastal plain, by some counts as many as ninety million, from Virginia to east Texas, and almost all of it is gone now, which is the quiet grief behind every longleaf you meet. They gave the South tar, pitch, and turpentine, the naval stores that caulked the wooden fleets of the eighteenth and nineteenth centuries and earned North Carolinians the nickname tar heels. Pinus palustris is the patient one. A seedling spends years as a dense green tussock, looking for all the world like a clump of grass and fooling everyone who doesn't know better, while underground they drive a deep taproot and wait out the fires that clear their rivals. Then they bolt, throwing up a single thick candle of a stem before they bother with branches. The needles are the longest of any eastern pine, well past a foot, hanging in soft fountains and catching wind like nothing else in the genus. Give one sun and room and you are planting the architecture the gopher tortoise and the red-cockaded woodpecker were waiting for. They ask only for patience, and they reward it for three hundred years.
Pistacia chinensis, the Chinese pistache, is a medium-sized deciduous tree and a close relative of the pistachio nut, though this species carries no crop for the table. What the tree offers instead is one of the finest autumn shows in the warm South: lustrous, dark green compound leaves that ignite, nearly all at once, into a fire of scarlet, orange, and red before they fall.
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.
A refined and rarely offered evergreen from New Zealand, Podocarpus acutifolius forms a dense, finely textured silhouette of short, sharp-tipped leaves that give the plant a crisp, architectural presence. Heat-tolerant and well suited to the southern United States when properly sited, this uncommon conifer offers structure, restraint, and year-round depth in the landscape.
