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.
This Phoebe is a broadleaf evergreen tree in the laurel family, Lauraceae, and a relative of the redbay and the avocado in the genus Persea. The genus Phoebe gathers more than fifty species of evergreen trees and shrubs across subtropical and tropical Asia, long known in China as nanmu and prized for hard, fine-textured, aromatic timber used in fine furniture and building since ancient times.
Prunus caroliniana, the Carolina cherry laurel, is a fast, dense broadleaf evergreen native to the coastal plain of the southeastern United States, from North Carolina to Texas. The glossy, deep green, finely toothed leaves and tight, upright habit make the tree one of the South's most useful evergreen screens, and the crushed foliage carries the sharp almond, maraschino-cherry scent that marks the genus.
Prunus umbellata, the flatwoods plum, is a picturesque small deciduous tree native to well-drained soils across the southeastern United States. Where the Chickasaw plum forms suckering thickets, the flatwoods plum grows as a single, gnarled, small tree with rough, dark bark and a wide, open crown, an old-field and fence-row character that reads as quietly beautiful in age.
Quercus acerifolia is one of the rarest oaks in North America, and one of the most quietly beautiful. The name says the first thing you notice: acerifolia means maple-leaved, and the upper leaves really do look like a sugar maple's, often as wide as they are long, cut into three to five sharp, glossy lobes that turn deep red and burgundy in fall. A close relative of the Shumard oak, maple-leaf oak grows as anything from a stunted, multi-trunked shrub on a windswept ridge to a single-trunked tree of forty or fifty feet in cultivation.
Quercus agrifolia, the coast live oak, is the evergreen oak of the California coast, the gnarled, dark-canopied tree that shades the golden hills of Steinbeck country and spreads heavy limbs over ranchland and canyon. The holly-like leaves are small, thick, and leathery, glossy dark green above with a spiny-toothed edge, and the tree holds them year round, casting the deep, cool shade that is the plant's signature. Left room, coast live oak builds a broad, low, romantically crooked crown.
Sand live oak is the live oak of the sandhills, a tough, evergreen cousin of the great Southern live oak scaled for drier, leaner ground. Where Quercus virginiana spreads into a vast shade tree, this species usually stays a small tree or even a shrub, dark and dense and salt-proof, holding leathery evergreen leaves through the year on the deep, dry sands of the coastal plain.
Georgia oak is a rarity in every sense, a small, refined red oak so restricted in the wild that most people have never seen one. The species clings to the granite outcrops of west-central Georgia and central Alabama, the flatrock country around Stone Mountain, where thin soil keeps the plant stunted and shrubby; give the same tree good ground and it grows into a shapely small tree of fifteen to thirty feet, clothed in small, glossy, bristle-tipped leaves that turn red and burgundy in fall.
This is one of William Bartram's oaks. He came upon the tree on his travels through the southeastern backcountry in the 1770s, and the botanical name still carries his hand, Quercus hemisphaerica Bartram ex Willd., the species epithet meaning half-a-globe, for the little domed cap that sits like a skullcap on the acorn.
Shingle oak is the oak that fools people, an oak with no lobes at all. The glossy, dark green leaves are long, entire, and laurel-like, closer to a rhododendron or a bay than to the deep-cut foliage of most oaks, and only the single bristle at each leaf tip gives the family away. A medium to large deciduous tree of forty to sixty feet, neat and pyramidal when young and rounding with age, the tree brings a clean, distinctive texture that few other shade trees can match.
The name is the whole description: incana means hoary, gray-haired, and bluejack oak wears a coat of fine pale hairs that turns the foliage a soft blue-gray, almost silver in some lights, unusual in a genus that mostly trades in greens.
Turkey oak earns the name from the leaf, three-lobed and clawed and splayed exactly like the track a wild turkey leaves in sand, which is fitting, because sand is where these trees live. Quercus laevis is the signature oak of the deep sandhills, the droughty white-sand ridges of the longleaf country from the Carolinas to the Gulf, ground so poor and so hot that most trees simply decline the invitation.
This oak carries the name of a Pennsylvania parson. Gotthilf Heinrich Ernst Muhlenberg was a Lutheran minister who botanized on the side, thoroughly enough that the German-American botanist George Engelmann named the species for him, and then misspelled it: Engelmann set an umlaut over the u that Muhlenberg never used, and the rules of botanical naming have fossilized the slip ever since, transliterating it into the tongue-twisting muehlenbergii we are stuck with.
The cup gives them away. Most oaks set their acorns in a cup of overlapping scales, but Quercus myrsinifolia belongs to the ring-cupped oaks of East Asia, the Cyclobalanopsis, whose acorn sits in a cup banded with smooth concentric rings like a tiny stacked beehive.
Few oaks in North America are rarer. Quercus oglethorpensis went unnoticed by science until 1940, when the botanist Wilbur Duncan described the tree from material gathered in Oglethorpe County, Georgia, and gave the species the county's name. Even now Oglethorpe oak is known from only a scattering of stands across the Georgia and South Carolina Piedmont, with far-flung outliers in Louisiana and Mississippi, and the species sits on every serious list of oaks of conservation concern.
A small-to-medium evergreen oak unlike anything in the North American flora. Quercus salicina belongs to section Cyclobalanopsis of the oak genus, the ring-cupped oaks, an entirely Asian group of evergreen oaks distinguished from every American oak by the concentric rings on the acorn cup, rather than the overlapping scales of the red and white oak groups. Some taxonomists treat Cyclobalanopsis as a genus of its own. To grow this oak in a Southeastern garden is to bring in a fundamentally different evolutionary lineage, one that has been evolving in isolation in the temperate forests of Japan and Korea for tens of millions of years, in parallel with the separate American radiation. The result reads as recognizably Quercus in habit and presence, yet is architecturally distinct in nearly every detail.
Nuttall oak is named for Thomas Nuttall, the restless English-American naturalist who botanized the young United States more thoroughly than almost anyone of his generation. Long known as Quercus nuttallii, the tree now carries the name Quercus texana in most botanical usage, a change that has caused no end of confusion, since the name once belonged to a different oak. Whatever the label, this is a large deciduous red oak of the Southern bottomlands, at home in the floodplain forests of the Gulf Coast and the Mississippi valley.
Few trees carry the weight of the South the way the live oak does. Quercus virginiana is the massive, broad-spreading, long-lived evergreen oak of the coastal plain from Virginia to Texas, the tree of avenues and old plantations, of moss-hung branches reaching low and wide over generations of the same ground. Given room and time, a live oak grows far wider than tall, the great limbs sweeping out and often down to rest on the earth, and the whole tree becomes a piece of living architecture. Georgia named the live oak the state tree, and ancient specimens are landmarks across the Deep South.
The Southern live oak needs no introduction in the coastal South, where the great, spreading, moss-draped evergreens are as much a part of the landscape as the light. Quercus virginiana 'Bok Tower' begins from that familiar species but carries an unusual story and, perhaps, an unusual future.
Few native trees announce themselves as cheerfully as Sassafras albidum, whose leaves come in three shapes on the same branch: an unlobed oval, a two-lobed mitten, and a three-lobed silhouette like a splayed hand. A member of the laurel family, Lauraceae, and kin to bay, cinnamon, and spicebush, sassafras carries aromatic oils in every part, so that a snapped twig or crushed leaf releases a warm, root-beer sweetness. The common name traces back through Spanish to the colonial Southeast, where the tree was among the first American plants shipped to Europe as a marketable medicine.
Upright deciduous tree ultimately medium sized. Abundant small white flowers and attractive cinnamon colored bark make this a desirable ornamental. Generally easier to grow than other Stewartias. (See DIR)
