The garden's backbone: flowering trees, native and rare shrubs, and evergreens that hold their shape through every season. Many are Southeastern natives; others are quiet collector's plants you won't find at a big-box nursery, chosen for resilience and lasting, year-round interest.
Buddleia loricata, the mountain sagewood, is a rugged evergreen from the high Drakensberg of South Africa and Lesotho, and one of the hardiest of all the butterfly bushes. Unlike the familiar deciduous buddlejas, this species holds narrow, crinkled, sage-like leaves the year round, dark green above and felted silvery white beneath. The species epithet loricata means clad in mail or armored, a nod to that tough, quilted foliage, while the genus honors the English clergyman-botanist Adam Buddle.
A yellow-flowered butterfly bush, Buddleia x weyeriana 'Honeycomb' is a vigorous hybrid of Buddleia globosa and Buddleia davidii that the late Dr. Michael Dirr judged better than the older 'Sungold'. The plant came to Dirr from Crathes Castle Garden in Scotland, bought as the variety 'E.H. Wilson' but proving to be a very different and superior yellow butterfly bush, named 'Honeycomb' and a standout in Georgia trials, flowering as late as Thanksgiving.
Buddleja salviifolia, the sage-leaf butterfly bush, is a medium to large evergreen shrub from the sun-soaked hillsides of South Africa, and despite the exotic origin the plant has proven remarkably hardy in southeastern gardens, coming through winters at the University of Georgia's Athens trials with quiet resilience.

Few hardy shrubs put on a show like Caesalpinia gilliesii, the desert bird of paradise, whose summer flowers open clear yellow and send out a spray of long scarlet stamens like fireworks caught mid-burst. A legume from the dry country of Argentina and Uruguay, long naturalized across the American Southwest, the plant carries ferny, blue-green, mimosa-like foliage that sets off the flamboyant bloom. Botanists now place the species in the genus Erythrostemon, meaning red stamen, though gardeners still know the plant as Caesalpinia.
Callicarpa acuminata, the black beautyberry, is the Mexican cousin of the familiar American beautyberry, a deciduous shrub of arching branches that, in fall, lines the stems with clusters of small, shiny berries in glossy black rather than the usual purple. The dark fruit is a quiet, sophisticated turn on the beautyberry idea, set off by the green leaves and lingering into the cool months.
Callicarpa americana 'Bok Tower' is the white-fruited form of the American beautyberry, swapping the species' electric magenta for clusters of clean, pearly white berries that ring the arching stems in late summer and fall. The pale fruit is cool and luminous, lovely against the green leaves and a striking foil to the purple-berried kinds, and just as good for the birds.
Callicarpa formosana, the Taiwan beautyberry, is a handsome deciduous shrub that lines the stems with vivid purple berries in fall, the clusters glowing against the fading leaves for strong late-season color. Native to Taiwan and southern China, the Taiwan beautyberry is built for warm climates and keeps a fuller, more robust frame than the smaller Asian beautyberries.
An evergreen bottlebrush with arching to pendulous branches and dark green, lance-shaped leaves, Callistemon paludosus carries terminal, pink bottlebrush spikes freely in midsummer, an unusual color in a genus mostly given to red. Relatively cold-hardy for a bottlebrush, this is a graceful, easy shrub for a hot, sunny spot.
An exceptional cold-hardy bottlebrush, Callistemon rigidus 'Clemson' is a compact to medium evergreen shrub hung with brilliant red, brush-like flowers that bloom heavily in late spring and often rebloom through summer. Native to Australia, this selection defies expectations for the genus by thriving outdoors in upstate South Carolina, where winters are usually too cold for bottlebrushes.
Among the many bottlebrushes, most of which flower fire-engine red, Callistemon viridiflorus goes a different way, opening in greenish yellow brushes over short, prickly evergreen leaves. Native to Tasmania, this is one of the cold-hardier members of the genus and may hold to zone 7.
Camellia fraterna is a camellia stripped back to wild beginnings, a species from the hills of eastern China far removed from the big, blowsy blooms of the garden japonicas and sasanquas. Where those carry a few large flowers, this one covers slender, upright branches in a snowfall of small, single, white flowers, faintly pink outside and softly fragrant, that arch the stems with their sheer number. The small, pointed evergreen leaves and open, airy habit give the plant an easy, natural grace.
Camellia saluenensis is not the flashiest camellia in the garden, but few have done more to shape the ones that are. This upright, densely leafy evergreen carries small, single, funnel-shaped flowers in soft pink, opening from late winter into spring, and stands as one of the two parents behind the celebrated Camellia williamsii hybrids that carried camellia growing into colder gardens.
Camellia 'California Dawn' brings together two very different parents to make a large, generous flower for the far end of the year. A cross between the autumn-blooming Japanese Camellia sasanqua and the big, tender, large-flowered Camellia reticulata of Yunnan, this hybrid opens wide light-pink blooms, semi-double to loose peony form, the petals crimped and waved like crepe paper. The flowers arrive in fall and early winter, when the garden has mostly finished, and this camellia has grown and performed well in the Woodlanders garden.
Woodlanders collected this one in the pre-Andean foothills of northwest Argentina, which is exactly what the name says: praeandinum, before the Andes. The plant grows wild there between three and five thousand feet, in country that bakes by day and chills hard at night, and that upbringing shows. Heat that flattens lesser things does not faze this vine, which still comes back through a Zone 8 winter.
Buttonbush is a rounded, deciduous native shrub, easily trained as a small multi-stemmed tree, grown for the curious globe-shaped flowers that give the plant its name. From early summer into fall, creamy-white pincushion balls about an inch across stud the branches, each a sphere of tiny tubular flowers with projecting styles that lend a fireworks effect, intensely fragrant and alive with bees, butterflies, and other pollinators.

Ceratostigma willmottianum, the Chinese plumbago, is a small deciduous subshrub grown for one of the truest blues in the garden. From midsummer into autumn the wiry, bristly-leaved stems carry clusters of intense cobalt-blue flowers, each a slim reddish-purple tube opening to five pale-blue lobes, and as the season cools the foliage turns a rich red and bronze, so that blue flower and crimson leaf often share the plant at once.
Few native trees announce spring like Cercis canadensis, the eastern redbud, whose bare branches flush rosy pink and magenta weeks before the dogwoods open. The small pea-like flowers cluster not just along the twigs but straight from the older branches and even the trunk, a charming trick called cauliflory, and give way to broad, heart-shaped leaves. A small, graceful understory tree of eastern and central North America, redbud belongs in the legume family, kin to peas and beans.
Cercis yunnanensis, the Yunnan redbud, is an upright, vase-shaped deciduous tree that opens the spring with an abundance of magenta-pink, pea-like flowers, borne in the redbud fashion straight along the bare branches and older wood before the leaves appear. The heart-shaped leaves that follow are the tree's quieter distinction: glossier and more refined than those of most redbuds, giving a polished, clean-textured canopy through summer.
Leatherleaf is the quiet constant of the northern bog. Chamaedaphne calyculata, the only species in the genus, is a low, thicket-forming evergreen of the heath family that ranges right around the cold northern world, from the peatlands of North America east to the bogs of Finland and Japan, and southward in this country to the pocosins and acid bogs of the coastal plain, as far as South Carolina. Across that vast range, leatherleaf forms the dense, spreading colonies that hold a bog together and shelter the wildlife within.
For a week or two in late spring, the Chinese fringetree disappears under snow. Chionanthus retusus var. serrulatus is a deciduous small tree of East Asia, native to China, Korea, and Japan, and the great show is the flowering: dense, lacy, fringed panicles of pure white, each petal narrow and strap-like, smothering the canopy so thickly that the foliage all but vanishes. The genus name says as much, from the Greek chion, snow, and anthos, flower.
