The flora of a whole continent, grown for the garden. This collection gathers the trees, shrubs, vines, and wildflowers native to North America, plants that evolved here alongside the birds, bees, and butterflies that still depend on them.
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.
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.
In July, when most of the shade garden has settled into a holding pattern of foliage and waiting, Aesculus parviflora opens for business. The timing is the first surprise. The flowers are the second. Each panicle is a foot or more of tightly packed white tubular blooms with conspicuous pink-red anthers projecting beyond the petals, the whole spike held upright above the foliage like something assembled by a botanical committee that could not decide between elegant and extravagant and chose both. A mature colony in full bloom in midsummer is among the more spectacular events available to the shade gardener, and the hummingbirds and swallowtails arrive reliably.
A wide-spreading, suckering, multi-stemmed deciduous shrub of slow, deliberate growth, Aesculus parviflora var. serotina carries the same upright white bottlebrush flowers as the bottlebrush buckeye, but opens them two to three weeks later, well into the heat of summer. The overall shape is irregular and almost stratified, the branches layering horizontally, and the medium to dark green leaves turn a clear yellow in fall.
The red buckeye is the South's hummingbird herald, a clump-forming, round-topped deciduous shrub or small tree whose lustrous, palmately compound leaves break very early, often before the last frosts, and whose six-inch panicles of tubular scarlet-red flowers open in spring just as the ruby-throated hummingbirds return north. The bright bloom, unusual among the buckeyes, draws hummingbirds and bees in numbers and gives the plant a long place in the affection of native-plant gardeners across the southern United States.
Agarista populifolia, still catalogued nearly everywhere as Leucothoe populifolia, is the giant of a group otherwise built low to the ground. Where most leucothoes hug the shade at knee height, this one rises, sending up tall, erect stems that arch at the tips into a fountain of glossy evergreen leaves, and given years and room the shrub can pass for a small multi-stemmed tree of twelve to fifteen feet.
The century plant is the great architectural agave, a broad rosette of thick, gray green, spine-tipped leaves that can spread six to eight feet across, each leaf edged with hooked teeth and ending in a hard dark spine. The form is bold and symmetrical, a piece of living sculpture for a hot, dry corner, and the silver cast of the foliage carries the planting through every season.
A graceful native onion, Allium cernuum, the nodding onion, lifts loose clusters of pink to lavender, bell-shaped flowers that bend over in a soft arc at the top of slender stems, swaying through mid and late summer above tufts of grassy, blue-green foliage. The nodding habit gives the plant a particular charm, and the flowers draw native bees, butterflies, and other pollinators in good numbers.

Seaside alder is a medium to large deciduous shrub, sometimes a small tree, with glossy, oval, toothed leaves and a habit of doing things backward. Where every other native alder flowers in spring, Alnus maritima opens elongated catkins in the fall, then carries small, woody, pinecone-like fruits through winter for quiet ornament.
Amelanchier canadensis is the coastal-plain member of a confusing and much-loved genus, a suckering multi-stemmed shrub or small tree of fifteen to twenty-five feet that reads as a thicket in the wild and as an airy vase in the garden. The show begins absurdly early: white flowers in short upright racemes open on bare gray wood while the woods are still brown, hold for a week or so, and then go. Fruit follows in June, raisin-sized, ripening green to red to a deep purple-black, sweet with a faint almond note. Autumn runs from yellow through orange to russet-red, and the bark, smooth and silver-gray with darker striping, carries the winter.

Among the rarest of the serviceberries, Amelanchier nantucketensis is a low, thicket-forming shrub that Eugene Bicknell first described in 1911 from the sandplains of Nantucket, the Massachusetts island whose name the plant carries. Nantucket serviceberry belongs to a small, taxonomically slippery group within the rose family, so closely tangled with neighboring shadbushes that botanists have argued for more than a century over whether this is a true species or a stabilized hybrid. What sets the plant apart is disarmingly small: petals shorter than those of any other serviceberry in the Northeast, often dusted with pollen along their own margins, a quirk called andropetaly that appears nowhere else in the group.
Coastal serviceberry is the compact, low-growing member of a beloved native clan, a small deciduous shrub of the Atlantic coastal plain that spreads gently into colonies and opens clouds of white, five-petaled flowers in early spring, among the first shrubs to bloom as the woods wake.
Amelanchier x grandiflora is the apple serviceberry, a naturally occurring cross between two eastern natives, the downy serviceberry and the smooth Allegheny serviceberry, and 'Autumn Brilliance' is the selection that made the group famous. The Illinois nurseryman Willet Wandell found this seedling in his Urbana nursery and introduced the plant to gardens in 1986 under U.S. Plant Patent 5,717, choosing the seedling above all for the blaze of autumn color behind the name. Decades on, 'Autumn Brilliance' remains the most widely planted serviceberry in the trade, prized for a vigorous, gracefully branched frame and reliable good looks in every season.
Apple serviceberry, Amelanchier x grandiflora, is the graceful natural hybrid of two eastern native serviceberries, the downy and the smooth Allegheny, and 'Princess Diana' is among the loveliest selections of the group. The plant appeared in a cultivated garden in Elm Grove, Wisconsin, was propagated and introduced by Tom Watson of Christom Farms Nursery in Cambridge, Wisconsin in 1983, and was granted U.S. Plant Patent 6,041 in 1987, chosen for a wide, gracefully spreading canopy, generous white bloom, and fall color that arrives early and holds late. Where many serviceberries grow stiffly upright, 'Princess Diana' reaches outward, a small tree with the airy, layered poise the name suggests.
Smooth false indigo is a rare deciduous shrub of sandy southern streambanks, carrying pinnate, compound leaves whose leaflets are notably large and rounded, a softer, more luxuriant texture than the ferny foliage of the common false indigos. In early summer the branch tips raise slender spikes of tiny blue to purple flowers, each lit with the bright orange anthers typical of the genus.
Ampelaster carolinianus is a woody, scrambling, semi-evergreen vine that climbs through shrubs and over stream banks along the coastal plain of the southeastern United States, opening lavender-blue flowers in November and December when every other aster has long since finished. The climbing aster keeps a private schedule, and that contrary timing is the whole charm.
Most bluestars are smooth, cool customers; Amsonia ludoviciana is the outlier of the group. The Louisiana bluestar belongs to the dogbane family, Apocynaceae, and shares the clan's five-petaled, star-shaped flowers and milky sap, but the leaves set the species apart: narrow and willowy, and unusually clothed beneath with a grey-white felt, a woolly tomentum that catches the light and lends the whole plant a soft, silvered cast rare in the genus. In spring, clustered flowers of a clean sky-blue open at the tips of the upright stems, quiet and steely and worked over by the first butterflies of the season.
Dwarf bluestar is the compact, well-behaved member of the clan, a tidy mound of upright stems and soft green leaves topped in late spring with clusters of powder-blue, star-shaped flowers. Often treated as a low form of the eastern bluestar, Amsonia montana stays small and shapely, a fine choice where the taller bluestars would sprawl.
Eastern bluestar is the bluestar most gardeners know, a robust native perennial with broader, willowy oval leaves and the clear blue, star-shaped flowers that name the genus, carried in clusters at the stem tips in spring. Amsonia tabernaemontana grows happily in deep, moist soil in part shade, and rewards almost any reasonable site with bloom and easy good health.
Flame acanthus, better known as hummingbird bush, is a tough, airy deciduous shrub for hot, dry places, hung from late spring until frost with slender orange to red tubular flowers that ruby-throated hummingbirds cannot resist. Small, pointed leaves give a light, open texture, and the long bloom season makes Anisacanthus wrightii one of the best hummingbird plants for the southern garden.
