Among the most beloved of the eastern wild azaleas, Rhododendron periclymenoides drifts through the open woods and swamp margins of the eastern United States from New Hampshire and Massachusetts south to South Carolina, Tennessee, and Alabama, opening clouds of pink bloom just as the woodland wakes in spring. This selection breaks from the ordinary pink of the species: a soft lavender-purple color form discovered in Lancaster County, South Carolina, and introduced by Woodlanders, uncommon in the wild and rarer still in cultivation. Botanists once filed the species under the name Rhododendron nudiflorum, and the plant still answers to that older label in many an old garden book.
This native deciduous azalea is considered one of the finest of the American Azaleas. It has orange-red to red flowers in July and August, much later than most native azaleas. It is a rare species found only in western Georgia and eastern Alabama where it grows along sandy ravines and along stream banks. It is the logo plant for the famous Callaway Gardens at Pine Mountain, Georgia which has done much to preserve and popularize this species. Culture as for other native azaleas that prefer well-drained acid soil and light shade.
Michael Dirr, in his Manual of Woody Landscape Plants, sets the bar plainly: one of the finest azaleas, the flowers opening just as the leaves expand, with no adequate way to do the plant justice in the written word. The royal azalea earns the praise. Rhododendron schlippenbachii is a deciduous azalea of Korea and the neighboring corners of northeast China, the Russian Far East, and Japan, where the shrub forms the dominant understory across whole hillsides, blooming in soft drifts of pink from four hundred to fifteen hundred meters up the slopes.
The native deciduous azaleas of the southeastern United States bloom in a long relay, from the pinxters and Piedmont azaleas of March through the flame azaleas of April and May and on into July with the red of Rhododendron prunifolium. And then, once most gardeners have closed the azalea chapter for the year, Rhododendron serrulatum opens. Hammocksweet azalea is the last of the line, flowering in August and September and sometimes later still.
A three-hundred-year-old Japanese garden azalea that does not look quite like a rhododendron, does not look quite like an azalea, and does not really look like anything else. The leaves are narrow green ribbons, three to five millimeters wide and a couple of inches long, closer to willow or fine grass than to the broad rounded foliage of an ordinary tsutsuji. The flowers, opening in late April and May, follow the same grammar: deeply divided into long strap-like petals in lilac-pink to lavender-rose, tangled and knotted at first, then unfurling slowly into a shape that reads, depending on the eye, as a crane fly, a spider, or a piece of decorative garnish. Wabi-sabi made evergreen.
The glaucous swamp azalea is a native deciduous shrub of the wetland South and the eastern seaboard, a blue-leaved form of Rhododendron viscosum, the widespread swamp azalea that ranges from the Gulf Coast north into New England. The variety glaucum sets the plant apart with foliage washed in a soft blue-green, most striking on the leaf undersides, which flash pale as a breeze turns them. Where many shrubs falter, this azalea thrives in the consistently moist, even boggy ground of swamps, marshes, and stream banks.
The swamp azalea, Rhododendron viscosum, ordinarily opens white; this selection breaks pink. 'Roseum' is a rose-flushed form of the familiar native, chosen and introduced by Woodlanders from a plant of Aiken County, South Carolina provenance, a home-ground selection that carries the sweet, clove-like fragrance of the species in a warmer color. The swamp azalea ranges widely across the eastern United States, from the Gulf Coast north into New England, threading the wet margins of swamps, bogs, and stream banks where few other flowering shrubs will follow.
'Addison' began as a chance seedling of the Alabama azalea, Rhododendron alabamense, and grew into something none of the parents quite predicted. Surely a hybrid, though the exact parentage remains unknown, the plant carries large, dense, dome-shaped terminal clusters that blend shades of yellow, pink, and white in a single truss, a multicolored effect striking enough that the selection first went by the name 'Stunning'. Charles Webb, a good friend of Woodlanders, spotted and selected the seedling in Florida, and the plant now carries the name of one of his young granddaughters.
This hardy hybrid azalea is a piece of Woodlanders history, a deliberate cross made by the nursery's late founder, Robert Mackintosh. Mackintosh crossed the native roseshell azalea, Rhododendron prinophyllum, with the old hybrid group known as R. x kosterana, or mollis azalea, and the result is an upright, large-flowered deciduous shrub carrying bold orange trusses each marked with a splash of yellow.
'Casille' arose spontaneously, a chance hybrid among three of the southeastern native azaleas: the white, lemon-scented Alabama azalea, Rhododendron alabamense; the fragrant pink Piedmont azalea, R. canescens; and the fiery, unscented Oconee azalea, R. flammeum. From that three-way mingling came a deciduous shrub that blooms in mid-spring in a lively pastel blend, the flowers shifting through pink, white, and soft yellow with a subtle sweetness inherited from the fragrant parents. An exclusive Woodlanders introduction, the plant was named by George Mitchell for his wife.
A rare evergreen shrub or small tree from southern China and the neighboring subtropics, Rhodoleia championii is a connoisseur's plant, dramatic in bloom, refined in habit, and quietly excellent the year round. Thick, glossy, rounded leaves cloak the plant in deep green, and their softly glaucous, blue-gray undersides catch the light and every passing breeze, giving even the out-of-flower plant a handsome, layered presence.
The lesser-known of the two Hong Kong roses in the Woodlanders collection, Rhodoleia henryi is a handsome evergreen shrub or small tree from southern China and Taiwan, still little grown in the United States and, like much of the genus, occasionally muddled in the naming. Set beside the sister species Rhodoleia championii, this plant carries narrower, more pointed leaves, and the species is reckoned the more cold hardy of the two, a useful distinction for gardeners testing the edge of the range.
Jetbead is an old-fashioned, exceptionally tough deciduous shrub of the rose family, forming an open, multi-stemmed mound roughly three to six feet tall and four to nine feet wide on arching gray-brown stems. The opposite, sharply toothed leaves break very early in spring, and four-petaled white flowers about two inches across open at the shoot tips in May and June. Clusters of three or four glossy black drupes follow in fall and hang on well into winter, the shining beads that give jetbead the common name.
Fragrant sumac is a versatile deciduous shrub native across much of the eastern and central United States, where the plant threads scattered woodlands, rocky slopes, and open banks. The trifoliate leaves, often mistaken at a glance for poison oak, are entirely harmless, and a crushed leaf releases the clean, lemony-resinous scent that gives the plant every one of the common names, from fragrant sumac to skunkbush, depending on the nose. The genus name Rhus is the old Greek and Latin word for the sumacs, and the epithet aromatica names the scent directly.

'Gro-Low' is the ground-hugging form of the native fragrant sumac, a low, wide-spreading deciduous shrub that stays one to two feet tall while reaching six to eight feet across, knitting into a dense, weed-smothering carpet. The glossy trifoliate leaves are often mistaken at a glance for poison ivy or poison oak but are entirely harmless, and a crushed leaf gives off the clean, lemony scent that names the species.

Smooth sumac is a bold, colony-forming native shrub of the eastern and central United States, in time reaching the scale of a small tree, and one of the finest plants going for a hot, dry, sunny site where little else will thrive. The long, pinnately compound leaves give an almost tropical texture through summer, and the plant spreads by root suckers into broad, picturesque colonies, or can be held to a single tree-like specimen where the suckers are controlled.

Rhus javanica, better known today as Rhus chinensis, is the Chinese sumac or nutgall tree, a fast, adaptable deciduous large shrub or small tree of East and Southeast Asia, in time reaching fifteen to twenty-five feet. The pinnate leaves, carried on downy shoots and set along a distinctively winged leaf stalk, turn vivid yellow to red in autumn, and creamy panicles of small flowers open in late summer, feeding bees when much of the garden has finished.

Michaux's sumac is a low, colony-forming native shrub, rhizomatous and densely hairy, rising only one to three feet on erect stems from a spreading root system. The compound leaves turn beautiful shades of orange and red in fall, and the dwarf, running habit makes the plant a fine, well-behaved groundcover-scale sumac for a sunny to lightly shaded native planting.
Littleleaf sumac is a big, bushy deciduous shrub of west Texas, the Southwest, and adjoining Mexico, built for heat, sun, and drought. The compound leaves are made up of tiny leaflets that give a fine, almost feathery texture, and they turn rose to purple in fall, an unusual and lovely tone among the sumacs. Tough and dryland-hardy, the plant is well worth trying in the South and any hot, well-drained garden.
Staghorn sumac is a bold native shrub or small tree of the northeastern United States and Canada, growing fifteen to thirty feet on stout, forking stems clothed in fine velvety hairs, the texture and antler-like branching that give the plant the name. The big, pinnate leaves are bright green through summer and turn a spectacular blend of yellow, orange, and red in fall, one of the great autumn shrubs of the eastern flora.
