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 trees carry a collector's story as plainly as the paperbark maple. Ernest Henry Wilson gathered seed of Acer griseum in central China in 1901 for the Veitch nursery, and for most of the twentieth century nearly every paperbark grown in Western gardens traced back to that introduction and one that followed. The maple sets abundant winged samaras, yet most are empty, a parthenocarpic habit that leaves only a small fraction viable. That quirk is why the species has always been scarce, slow to propagate, and quietly treasured wherever a good specimen takes hold.
Acer rubrum 'Candy Ice' is a Woodlanders introduction, found in southwest Virginia by the late Norman Beal. We use Norman's original name, though the same tree has been circulated elsewhere as 'Snowfire'. This is an unusual variegated red maple, the leaves marbled in pink, white, and green, and the foliage burns early, among the first to color when fall arrives.
Korean mountain ash is the unusual member of the clan, a deciduous tree from Korea, recently moved by botanists from Sorbus into the genus Alniaria, with simple, finely toothed, alder-like leaves rather than the compound leaves of the familiar mountain ashes. White flower clusters open in May, and the fall foliage turns warm shades of orange and red.
A hybrid strawberry tree, Arbutus x andrachnoides crosses the strawberry tree, Arbutus unedo, with the Grecian strawberry tree, A. andrachne, and takes the best of both: white, bell-shaped flowers and pink, strawberry-like fruit on a small evergreen tree, over dark green leaves an inch and a half to four inches long. The real prize comes with age, when the bark peels away to a smooth, rich red-brown that rivals any madrone.
Carpinus caroliniana is a native tree that hides its best feature in plain sight, a smooth, gray, sinewy bark that ripples over the trunk like the muscles of a flexed arm, giving the common names musclewood and ironwood. This small, slow, dense understory tree of eastern North America carries fine, birch-like leaves and a rounded, layered crown. The wood beneath that muscled bark is famously hard and heavy, the reason ironwood stuck as a name.
Carya aquatica, the water hickory or bitter pecan, is a large native tree of the walnut family, reaching ninety feet and more in the wild. Across the American South the species dominates clay flats and the backwater ground near streams and rivers, reproducing aggressively by seed and by sprouts from roots and cut stumps, and forming a major part of the region's wetland forests, in part because the more marketable timber trees around the water hickory have so often been logged out.
Carya ovata, the shagbark hickory, is one of the great native trees of the eastern woods, as easy to know by the bark as by the nuts. Mature trunks shed long, gray plates that curl away at the ends and hang loose, giving the tree a genuinely shaggy silhouette against a winter sky. Beneath that ragged coat stands a tall, straight, long-lived hardwood that can shade a landscape for two centuries and more.
Few trees carry as much historical weight as the chestnuts, and Castanea mollissima carries it gracefully. This handsome, wide-spreading Chinese native stepped into the void left by one of the great ecological tragedies of the twentieth century, the near-total collapse of the American chestnut, and has been feeding people, wildlife, and the soil ever since. Come fall, the spiny husks crack open to reveal some of the largest, sweetest chestnuts a gardener can grow.
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.
For a week or two in late spring, the Chinese fringetree disappears under snow. Chionanthus retusus var. serrulatus is a deciduous small tree of East Asia, native to China, Korea, and Japan, and the great show is the flowering: dense, lacy, fringed panicles of pure white, each petal narrow and strap-like, smothering the canopy so thickly that the foliage all but vanishes. The genus name says as much, from the Greek chion, snow, and anthos, flower.
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.
Cinnamomum burmannii is the tree behind most of the cinnamon in an American kitchen, an evergreen of the laurel family whose fragrant inner bark, dried and ground, fills the great majority of the spice jars labeled simply cinnamon. Native to the highlands of Indonesia and across tropical Southeast Asia, this glossy-leaved tree is a cassia cinnamon, close kin to true Ceylon cinnamon, to the camphor tree, and to bay laurel, sassafras, and avocado. The whole plant is aromatic, from the leathery leaves to the spicy bark.
A rare evergreen tree from southern China, seldom seen in cultivation, Cinnamomum wilsonii belongs to the cinnamon and camphor clan, and the kinship shows in the glossy, leathery, dark green leaves, four to five inches long and marked with three bold veins that run nearly to the tip. Crushed or bruised, the foliage and bark give off the warm, spicy fragrance the genus is loved for. The Chinese name, chuan gui, places the tree in Sichuan and the mountains of the south, where the tree grows large and the aromatic bark has long been valued.
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.
This elegant small tree carries a graceful, vase-shaped habit that rounds out with age. Blooming two to three weeks after Cornus florida, the kousa dogwood opens striking, pointed flower bracts in late spring to early summer, extending the dogwood season. The bracts surround clusters of tiny true flowers in a star-like display that sets this dogwood apart.
This Chinese dogwood is a spreading, small to medium deciduous tree with clean foliage and showy white-bracted flowers. Unlike the native American flowering dogwood, the bracts are sharply pointed. The tree flowers about a month later than Cornus florida, and is apparently immune or resistant to some of the disease problems that trouble Cornus florida in certain areas. A fine ornamental for an open, semi-shady lawn or border.
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.
