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.
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.
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.

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.
These are the grandchildren of a legend. The Wye Oak of Wye Mills, Maryland, was the greatest white oak in the country, a single tree that stood more than four hundred and sixty years and served as Maryland's state tree until a storm finally brought the giant down in 2002. Quercus alba 'Grandchildren of Wye Oak' are seedling-grown descendants of that famous tree, carrying the bloodline of an American icon into gardens that have room for the long view.

The name is a promise the tree keeps only at the very end of the year. Coccinea is Latin for scarlet, and scarlet oak earns it in late October, well after the other oaks have turned and dropped, when the whole crown ignites into a clean, carrying red that holds for weeks and can be seen across a valley. On a good tree in the right soil, this is the best fall color the genus offers, which is saying something.
The overcup oak is named for a small piece of botanical theater: an acorn so nearly swallowed by its cup that only the tip shows, sealed up as if against the floodwaters the tree was born to. Quercus lyrata is a creature of the southern bottomlands, the broad floodplains and backswamps from the Mississippi Delta to the Carolina river bottoms, standing through the cycles of flood and drawdown that drown lesser trees.
Quercus michauxii is a big, generous bottomland oak that borrows the best of two better-known relatives: the pale, flaky, handsome bark of the white oak, and the large, coarsely toothed, chestnut-shaped leaves of the chestnut oak. The result is one of the noblest of the Southern hardwoods. In Coker and Totten's Trees of the Southeastern States, a 1931 letter from James Henry Rice, Jr. of Colleton County, South Carolina, put it plainly: "It is a noble and beautiful tree and might be termed majestic with no violence to the language."
The first surprise of Quercus phellos is that nobody believes they're an oak. The leaves are narrow and untoothed, willow-like, finer than an oak has any right to be, and they turn soft yellow before they fall; only the acorns, small and round and produced by the thousand, give the game away.
There is a small drama in this oak's name. It honors Benjamin Franklin Shumard, a physician turned geologist who became the first State Geologist of Texas and who, decades before the oil boom, noted petroleum seeping up at several spots across the state. The man who named the tree for him in 1860 was his own assistant, Samuel Buckley, who would later turn on Shumard in print, call him incompetent, and take the state geologist's post for himself, all of which makes the enduring courtesy of the name faintly delicious. The tree has outlasted the quarrel.
Quercus stellata, the post oak, is one of the great toughs of the eastern white oaks, a tree born to dry uplands, old fields, and rocky ridges from the sandy hills of the Carolinas and Georgia across the Piedmont and into the prairies of Texas and the Midwest. Where soils are thin and the summers unrelenting, post oak has made a living, holding ground against wind, sun, and time itself.
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.

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.

The swamp rose is one of the few roses that truly loves wet feet, a tall, graceful native shrub of the eastern United States that grows wild along pond edges, streambanks, and in the low, seasonally flooded ground where garden roses would drown. Reaching four to eight feet on arching, sparingly thorny canes, the plant opens fragrant, single, clear pink flowers through the summer, each a simple five-petaled saucer around a boss of gold stamens, a soft, untamed beauty far from the tidy hybrid tea.
Bald cypress is the great deciduous conifer of the southern swamp, a long-lived, stately tree of river margins, bottomlands, and blackwater sloughs across the southern United States, and one of the most beautiful native trees the region has to offer. Soft, feathery, two-ranked needles clothe the branches in a light, bright green through summer, then turn a warm russet-orange and fall, leaving a broad, pyramidal frame bare for winter.
A native tree that bites back, and can numb a toothache. Zanthoxylum clava-herculis, the toothache tree or Hercules' club, is a small to medium deciduous tree of the citrus family, native along the coastal Southeast from Virginia to Florida and Texas. The genus name Zanthoxylum means yellow wood, and the species clava-herculis, the club of Hercules, names the stout, spiny, club-shaped trunk that is the tree's signature.
Acer barbatum is a medium to large deciduous tree of rounded, oval form, a southern cousin of the northern sugar maple and sometimes filed under Acer saccharum subsp. floridanum or Acer floridanum. The Florida maple is built for heat in a way the northern relative is not, smaller in every part, with leaves that are whitish beneath and a constitution suited to long, humid summers. In the wild these trees favor fertile, moist, well-drained, often calcareous ground, frequently along streams and in rich hammocks from Virginia south to the Florida panhandle and west into Texas.
