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.
Magnolia cordata is the yellow cucumbertree, a smaller, more garden-friendly cousin of the towering cucumbertree magnolia and, botanically, a variety of it, Magnolia acuminata var. subcordata. Where the parent species climbs seventy feet and hides greenish flowers high in the canopy, this yellow-flowered form stays a modest tree of twenty-five to thirty-five feet and carries the trait breeders have chased for generations: tulip-shaped blooms of clear, canary yellow.
Magnolia macrophylla, the bigleaf magnolia, holds a national record: the largest simple leaves and the largest flowers of any tree native to North America. A deciduous magnolia of rich, sheltered woodlands scattered from West Virginia south to Louisiana and Florida, the tree is scarce in the wild and unforgettable in leaf, with blades up to three feet long and a foot wide, deep green above and a soft silvery white beneath that flashes when the wind turns them.
Sweetbay magnolia is one of the loveliest and most useful of the native magnolias, a tree of moist and swampy ground across the eastern United States from Massachusetts to Texas. The northern plants, Magnolia virginiana var. virginiana, are shrubby and deciduous; the southern, var. australis, grow into larger, evergreen trees. All share the sweetbay's gifts: leaves silvery white beneath that flash in the wind, and creamy, intensely fragrant flowers with a clean lemon scent.
Sweetbay magnolia ranges across the moist ground of the eastern United States, from Massachusetts to Texas, and in the South becomes the larger, evergreen tree botanists call Magnolia virginiana var. australis. 'Santa Rosa' is a superior evergreen selection of that southern variety, a Woodlanders introduction gathered in Santa Rosa County, in the Florida panhandle.
Sweetbay is one of the loveliest and most useful of the native magnolias, and this is Sweetbay from the far western edge of the range, the big-leaved, big-flowered form of the Louisiana and east Texas country long known in gardens as Magnolia virginiana ludoviciana. Set against the typical species, these western-Gulf plants carry noticeably larger leaves and flowers, with soft down on the undersides of the leaves and on the flower buds, and grow as small to medium trees of a more open, airy habit.

There is something quietly instructive about the range of Magnolia virginiana. The species runs from the cold, swampy woods of Gloucester, Massachusetts, where a small population clings to the northern edge of the natural territory, all the way down to the Gulf Coast of Texas, a span of climate and geography that would seem to demand two entirely different plants. In the North the sweetbay obliges by turning deciduous, multi-stemmed, and compact, staying modest in deference to the winters. In the South the same species becomes something else entirely, a tall, evergreen tree of real stature. Botanists eventually gave the northern form a name of its own, var. virginiana, and that is what Woodlanders grows here, raised from seed collected at the Massachusetts limit of the range.

The red mulberry, Morus rubra, is the eastern woodlands' own mulberry, a medium to large deciduous tree native across the eastern United States from New England to Texas. The genus name Morus is simply the old Latin word for mulberry, and rubra, red, points less to the ripe fruit, which darkens to near black, than to the reddish cast of the young growth. Broad, heart-shaped, sandpaper-rough leaves clothe a wide, rounded crown, and where a female tree grows the summer branches hang heavy with blackberry-like fruit.

Nyssa ogeche, the Ogeechee tupelo, is a medium-sized deciduous tree of the southeastern Coastal Plain, at home from southern South Carolina through the Ogeechee valley of Georgia into northern Florida and Alabama. The genus name honors Nyssa, a water nymph of Greek myth, and the tree lives up to the name, thriving along creeks, river swamps, and seasonally flooded bottoms where the soil stays acidic and wet.
Oxydendrum arboreum, the sourwood, is one of the loveliest and most distinctive trees of the Eastern American woods, and among the very last to flower each year. The name tells the story twice over: Oxydendrum joins the Greek oxys, sour or sharp, and dendron, tree, while the common name echoes the same tang, for the leaves, twigs, and bark all taste sourly of oxalic acid when chewed. A member of the heath family alongside azaleas, rhododendrons, and blueberries, sourwood stands alone as the sole species in the genus, native to well-drained, acid woodland soils from southern Pennsylvania to the Florida panhandle and west toward Louisiana, most abundant in the lower Appalachians.

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.
