The plants you grow for your grandchildren. Canopy trees are the garden's largest and longest-lived residents, the shade-throwers and skyline-makers that set the scale of everything planted beneath them.
Few native trees announce spring like Cercis canadensis, the eastern redbud, whose bare branches flush rosy pink and magenta weeks before the dogwoods open. The small pea-like flowers cluster not just along the twigs but straight from the older branches and even the trunk, a charming trick called cauliflory, and give way to broad, heart-shaped leaves. A small, graceful understory tree of eastern and central North America, redbud belongs in the legume family, kin to peas and beans.
The native fringetree is one of the great small trees of the southern spring. Chionanthus virginicus, a deciduous large shrub or small tree, often multi-stemmed, hangs the whole canopy with fleecy, drooping panicles of narrow white petals in spring, soft as torn paper and lightly fragrant, a look that earned the old country names old man's beard and grancy graybeard. On female plants the flowers give way to clusters of raisin-sized, deep blue-purple fruits that birds take quickly.
American yellowwood is one of the loveliest and least common of our native trees, a broad, round-headed deciduous tree grown for three good seasons of interest. In late spring, usually May, long pendulous panicles of white, pea-like flowers hang from the branch tips, sweetly fragrant and wisteria-like, a spectacle in the years the tree chooses to flower heavily. Summer brings clean, bright-then-deep green compound foliage, and autumn a dependable, clear golden yellow that is among the best fall color of any hardwood. The smooth gray bark, beech-like, holds the winter garden.
There is a version of the flowering dogwood almost nobody has met. Cornus florida 'Suwanee Squat' was found in Suwannee County, Florida, by Bob Simons, a forest ecologist who spent half a century protecting the wild hardwood country of north Florida. As a young man in the early 1970s he walked a mixed-hardwood hammock outside Gainesville, decided the place was worth saving, and talked ten landowners and the state into making it San Felasco Hammock; that became the pattern of his life. A man who knew that kind of forest the way most of us know our own street is exactly the sort to notice a dogwood doing something a dogwood is not supposed to do. Woodlanders introduced his low, sprawling oddity to cultivation, and the plant has stayed scarce ever since, the kind of tree you mostly hear about secondhand from someone who saw one and never got over it.
Cornus florida, the flowering dogwood, is the beloved understory tree of the eastern North American woods, widely planted for the great show of white spring bracts (the true flowers are the small green knot at the center), and, in selections like this one, pink. A deciduous woodland tree that grows in moist, well-drained soil in sun or high, dappled shade, the dogwood rewards careful planting: set the root flare high, and never plant too deep.
Crataegus harbisonii is a small, thorny, deciduous hawthorn with unusually large leaves for the genus, white spring flowers, and red fall fruit. Behind that modest description stands one of the rarest trees in North America: Harbison's hawthorn was perhaps once fairly common around central Tennessee, but is now all but extinct in the wild.
The parsley haw, Crataegus marshallii, is a distinctive and graceful small native tree, named for the shiny, deeply dissected, parsley-like leaves that set the whole genus apart at a glance. White flowers centered with rosy-red stamens open in spring, followed by bright red fruit that lingers into fall.
Diospyros texana, the Texas persimmon, is a small, tough native tree grown above all for the bark, which peels away in thin flakes to reveal a smooth, mottled patchwork of white, gray, and pink beneath. Intricately and crookedly branched, this is a sculptural little tree, as handsome bare in winter as it is in leaf. A creature of the Texas hill country and northern Mexico, the Texas persimmon shrugs off heat, drought, and lean limestone soil that would defeat softer plants.
The botanical name reads like a compliment: Diospyros joins the Greek dios, divine, to pyros, grain, so the genus translates roughly as "fruit of the gods," a lofty title for a tree that drops sweet, homely orange fruit onto the forest floor each autumn. The common name travels the other direction, plain and American, from the Powhatan word putchamin for a dried fruit, a reminder that Native peoples were drying persimmons into cakes long before the botanists arrived.

Anacua, Ehretia anacua, is one of the signature small trees of the south Texas brush country and the lower Rio Grande, a member of the borage family that goes by a small crowd of names. The rough, sandpapery upper surface of the leaves earns the tag sandpaper tree, while old-timers along the border call the tree anacua or, corrupted through generations, knockaway. Evergreen to semi-evergreen depending on the winter, the anacua holds dark green, leathery leaves that feel like fine grit under a thumb.
The American beech is one of the great presences of the eastern woods, a large, slow-growing deciduous tree that ranges through rich forests from southern Canada to the Gulf. Toothed oval leaves, several inches long, emerge a clean bright green, turn clear yellow in fall and then a warm russet-brown, and cling to the branches through much of winter, a habit called marcescence that gives the bare woods a soft papery whisper. The trunk is the signature: smooth, silver-gray, and elephantine, so inviting that generations have carved their initials into the living bark, a temptation best resisted since the wounds never truly heal.
Gymnocladus dioicus, the Kentucky coffeetree, is a bold, handsome native shade tree that keeps its own unhurried calendar, among the last trees to leaf out in spring and the first to stand bare in fall. That long leafless season gave the tree a curious name, which means naked branch, and the winter silhouette of thick, blunt, sculptural limbs is a feature in itself. Hillier's great manual calls the Kentucky coffeetree one of the most handsome of all hardy trees, and few who grow one would disagree.
Carolina silverbell is one of the loveliest of the small native trees of the Southern woods, a deciduous tree of the southeastern United States that lights the spring understory with hundreds of little white bells. In April and May, before or as the leaves unfold, the branches hang thick with clusters of nodding, bell-shaped white flowers, an effect much like a flowering dogwood but softer, and just as welcome at the woodland edge.
In spring, the bare gray branches of the two-wing silverbell fill with small white bells, three to six to a cluster, hanging along the year-old wood like a run of tiny lanterns. Each flower is a half-inch, four-lobed cup, and en masse they turn a modest understory tree into one of the quiet highlights of the southern woodland spring. This silverbell grows as a large multi-stemmed shrub or a small tree, rarely more than thirty feet, with an open, layered frame that lets light through to whatever grows below.
Of all the silverbells, this is the one plant hunters remember. Halesia diptera var. magniflora is the large-flowered form of the two-wing silverbell, and the difference is not subtle: the white, bell-shaped flowers run half again larger than the type, sometimes an inch and more across, with the lobes cut so deeply that each bloom flares open like a little white star rather than a closed bell. In full flower, before the leaves are fully out, the branches all but vanish beneath them, and a mature specimen becomes a cloud of white in the April woods.
Ilex opaca, the American holly, is the classic evergreen holly of the eastern woods, a medium-size tree with tough, leathery, spine-edged leaves and, on female trees, the bright berries that have meant Christmas for generations. 'Fallaw' keeps the familiar form but changes the color of the fruit: where the wild tree ripens red, this selection hangs clear amber-yellow berries, an uncommon and cheerful contrast against the dark evergreen foliage.
Ilex opaca, the American holly, is the classic evergreen holly of eastern woods, a medium tree with tough, spine-edged, leathery leaves and the bright red berries that have meant Christmas for generations. 'Selected Red' is one of the good ones, a female clone Woodlanders propagated from a group of hollies planted many years ago in Aiken, South Carolina, chosen for very good foliage and an abundant crop of bright red fruit.
The Foster hollies are among the most planted evergreens in the South, a group of hybrids between the native dahoon, Ilex cassine, and the native American holly, Ilex opaca, raised at Foster Nursery in northern Alabama. They carry narrow, dark, lightly spined leaves on a neat pyramidal frame and fruit heavily in red. 'Alagold' is the exception in color: a yellow-berried seedling of Foster number two, hanging clear amber-gold fruit each winter against dark olive-green foliage, on the same dependable, upright, tree-like holly.
Magnolia acuminata, the cucumbertree, is the giant of the native magnolias and the only one hardy far into the North. A deciduous forest tree of the eastern United States, most majestic in the southern Appalachians, the cucumbertree can rise seventy to ninety feet into a broad, rounded canopy, valued as a fast-growing, exceptionally hardy shade tree for parks and large lawns.
