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.
The tung oil tree is a handsome medium-sized deciduous tree, broad and spreading, with large heart-shaped to lobed leaves up to ten inches across and showy panicles of white flowers, blushed pink and orange at the throat, that open in spring before or with the new foliage. Few flowering trees of the Deep South make a fuller spring show.
The pawpaw is a small, tropical-looking deciduous tree with large, drooping leaves and the largest edible fruit native to this country. In mid to late summer the green, mango-shaped fruit softens to a fragrant custard, banana and mango in one, around rows of big dark seeds, relished by people and raccoons alike. The crushed leaves carry a distinctive odor, and the whole tree reads more like the tropics than a temperate woodland.
This is a tree you harvest from a boat. Crataegus opaca, the western mayhaw, grows wild in the flooded bottoms of the Gulf Coastal Plain, the cypress sloughs and pond margins of east Texas, Louisiana, and the Deep South, and when their fruit ripens in late spring it drops straight into the water and floats. For generations Southern families went out in May with boats, nets, and scoops to gather the bobbing red haws off the surface, a fast three weeks of work that turned into a year's worth of jelly. The name says as much: mayhaw, for the month, and haw, the old word for hawthorn.
Juglans nigra, the eastern black walnut, is one of the great trees of eastern North America, a towering, long-lived hardwood native from the Appalachians and Midwest to the Mississippi Valley, most at home in deep, rich, moist but well-drained soils along river bottoms and fertile uplands. Large pinnate leaves cast a broad, airy shade in summer, leaf out late in spring, and drop early in fall to a soft gold, making way for the tree's most famous gift, the crop of hard-shelled nuts.

The Lauraceae is an underappreciated family. Its members include cinnamon, camphor, bay laurel, and the avocado, which gives you some sense of the range of things the family has contributed to human civilization. Machilus thunbergii is another member in good standing, though these trees arrive in the Western garden with considerably less fanfare than their relatives. In East Asia they are well known: a coastal evergreen tree native to Japan, Korea, Taiwan, China, and Vietnam, valued for timber, planted as a street tree, and the source of makko, a powder derived from the bark and used for centuries to bind incense and, in a more practical application, to repel mosquitoes. The bark also has a history in traditional medicine. Here, in other words, is a tree that has been useful to people for a very long time, which is not a bad thing for a plant to be.
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.
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.
Pistacia chinensis, the Chinese pistache, is a medium-sized deciduous tree and a close relative of the pistachio nut, though this species carries no crop for the table. What the tree offers instead is one of the finest autumn shows in the warm South: lustrous, dark green compound leaves that ignite, nearly all at once, into a fire of scarlet, orange, and red before they fall.
Quercus alba, the white oak, is the grandfather of the eastern forest, a slow, massive, long-lived tree that can stand for centuries and outlast the people who plant them. The most famous of all was the Wye Oak of Wye Mills, Maryland, a single white oak that stood for more than four hundred and sixty years and served as Maryland's state tree until a storm brought the giant down in 2002. The broad, rounded crown, the pale, scaly, ash-gray bark, and the deeply lobed, blue-green leaves are the picture most people carry of an oak.

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.
To see Styrax japonicus properly you have to look up. The leaves ride along the tops of the branches, all turned to the sky, while underneath, in late spring, hang rows of small white bells on slender stalks, so the whole horizontal tier of the tree seems lit from below. Stand beneath one in bloom and the common name explains itself.
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.
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.
