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.
A broadleaf evergreen with a story, this variegated tanbark oak came into the country from Japan through the late Dr. Fred Meyer of the United States National Arboretum, a botanist and tireless plant explorer, and was almost certainly first offered to American gardeners by Woodlanders. The draw is the foliage: dense, leathery, glossy leaves, each dark green blade split by an irregular central streak of gold and cream, so that a whole tree seems lit from within. Plant Delights later distributed the same selection under the name 'Starburst,' and both names point to this one bright-leaved plant.
Lithocarpus henryi, the Henry tanoak, is an evergreen cousin of the oaks that few gardeners have met. Native to the mountain forests of central China, the tree carries long, narrow, pointed leaves of glossy deep green and builds, in time, a dense, rounded evergreen crown of fifteen to twenty-five feet. Among a genus of mostly tender species, this one ranks as the hardiest, which is what makes the Henry tanoak worth seeking out for milder temperate gardens.
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.
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 kobus, the kobus magnolia, is a hardy, deciduous magnolia from Japan, grown for a froth of white, lightly fragrant flowers on bare branches in earliest spring. The Japanese name kobushi, from which the species takes its epithet, means fist, a nod to the plump flower buds and knobby young fruit that look like a small clenched hand.
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.
Magnolia sprengeri 'Diva' is the aristocrat of the pink magnolias, a large, rare deciduous tree from the mountains of western China that smothers itself in spring with big, saucer-shaped flowers of deep rose-pink, sweetly fragrant and opening on bare branches before the leaves. Six to eight inches across and carried in abundance, the blooms make one of the most breathtaking sights in the early garden, yet the tree remains surprisingly little known in American gardens.
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.

Myrica rubra, the Chinese bayberry or yangmei, is a fruiting evergreen tree from the misty mountains of East Asia, revered for centuries across China and Japan for tangy-sweet berries and an elegant, shapely form. Imagine cherries and cranberries with a botanical lovechild that had the moodiness of a plum and the antioxidant punch of a superfruit, and something close to yangmei would be the result. The current stock is female, tissue-cultured clones of a named selection.
There is something almost meditative about Nageia nagi. Named from the Japanese word nagi, meaning both calm and to mow down one's troubles, this ancient conifer carries a quiet gravitas few trees can match. At the Nyakuoji Shrine in Kyoto a sacred nagi tree has stood for centuries, believed to cut through hardship and leave peace in its wake, and sprigs of nagi have long passed between lovers as a token of steadfast devotion, the leaves too tough and resilient to tear easily, a metaphor that has endured for a thousand years.
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.

There is a moment in late winter, before anything else in the garden has stirred, when Parrotia persica opens the first flowers. They have no petals, just a tight cluster of crimson stamens emerging from scaled buds along bare grey branches, small and startling against the cold. Most people walk past them. The ones who stop tend to become collectors.
Parrotia persica 'Lamplighter' is a rare variegated form of the Persian ironwood, grown above all for the foliage: each leaf carries a broad, irregular border of creamy white around a grey-green center, so the whole canopy reads as soft, dappled light through the growing season. New growth can flush pink and rose before the variegation settles, and the effect is luminous rather than loud, a tree that brightens a shaded corner the way a lit lamp does, which is presumably how the selection came by the name.
For most of botanical history the genus Parrotia was thought to hold a single species, the Persian ironwood (Parrotia persica) of the Caspian forests. Then came a small Chinese tree with a long and tangled paper trail. A fruiting specimen gathered in Jiangsu Province in 1935 sat in a herbarium drawer until 1960, when the botanist H.T. Chang described the specimen as a witch-hazel under the name Hamamelis subaequalis. The living tree, meanwhile, had vanished. The species was presumed extinct for half a century, until a 1988 expedition found the tree again, and only in the late 1990s did DNA settle the question once and for all: no witch-hazel at all, but a second Parrotia, sibling to the Persian across some 3,500 miles of Asia.
Phoebe chekiangensis is one of a group of Chinese evergreens that could give the American South a whole new kind of shade tree. Upright and clean-limbed, the tree carries dense, leathery, dark green leaves much like those of the related redbay, glossy and handsome the year round, and grows at a steady pace into a small to medium tree of real presence.
